This compelling open letter addresses one of the most pressing issues of our time - climate change - from a unique perspective: the exclusion of children under 18 from global climate decision-making processes.\r\n\r\nThrough this formal letter to UN Secretary-General Antonio Guterres, organizations like Save the Children and Child Rights Connect advocate for meaningful inclusion of young climate activists in international policy discussions. The letter showcases how children worldwide have become powerful agents of change, sparked by figures like Greta Thunberg.\r\n\r\nThis chapter combines reading comprehension, formal letter analysis, and advanced grammar practice while exploring themes of youth activism, climate justice, and the importance of inclusive decision-making in global governance.\r\n\r\n**Skills Focus:** Formal Letter Analysis, Advanced Reading Comprehension, Reported Speech, Letter Writing  \r\n**Time Required:** 8-10 periods\r\n\r\n## 📚 Learning Objectives\r\nAfter studying this chapter, you will be able to:\r\n- Analyze formal letters and understand their structure and purpose\r\n- Extract key arguments and supporting evidence from advocacy texts\r\n- Understand vocabulary related to climate change, activism, and international organizations\r\n- Master complex reported speech transformations\r\n- Write formal letters to authorities requesting action\r\n- Evaluate the role of youth in global decision-making processes\r\n- Discuss climate change issues and potential solutions\r\n- Apply reading comprehension techniques effectively\r\n\r\n## 📖 Reading Text: Open Letter to UN Secretary-General Antonio Guterres\r\n\r\n### Letter Header and Address\r\n**His Excellency Antonio Guterres**  \r\nUnited Nations Secretary-General  \r\nUnited Nations Secretariat  \r\n42nd Street, New York, NY 10017  \r\n\r\n**Date:** 7 August 2020  \r\n\r\n**RE:** Inclusion of children in the Youth Advisory Group on Climate Change\r\n\r\n### Opening and Congratulations\r\nYour Excellency,\r\n\r\nCongratulations on your recent announcement of seven young climate leaders between the ages of 18 and 28 years old to your **Youth Advisory Group on climate change**, who will advise you regularly on **accelerating** global action and the ambition to **tackle** the worsening climate crisis. We appreciate this important focus on bringing young leaders into **decision-making** and planning processes related to climate action. We also welcome the **emphasis** you place on receiving and giving **frank** and fearless advice, and the urgency of **holding** government and **corporate** leaders to **account** on climate action.\r\n\r\n### The Core Concern\r\nWe are disappointed, however, that you have not expanded this list of young climate leaders to children in all their **diversity**. Millions of children took part in school strikes for climate action in 2019 and early 2020 and **demonstrated** their **outrage** and constructive solutions in equal measure. They have been **agents** of change in the climate debate using their channels of **influence** - schools, social media, and street protest - to **catalyse** **global** **activism** on the climate crisis.\r\n\r\nWe have seen children from the global North to the global South **engaging** with political and corporate leaders - in their home countries and also within the international system - most recently at the UN Human Rights Council - claiming their right to a safe, clean, healthy and sustainable environment as critical foundation to realizing their wellbeing and rights.\r\n\r\n### Youth Leadership Examples\r\nIt was, after all, a child, **Greta Thunberg**, who sparked this global movement through an **inspiring** solo protest in 2018. By 2019, she was able to rightly **assert**: \"We proved that it does not matter what you do and that no one is too small to make a difference.\" In 2020, children are saying the same thing.\r\n\r\nLike **Fabrizio**, a 16-year-old boy from Peru, who told us on a recent child-led online conversation, \"The Future of Children is **at stake** now, tomorrow will be too late.\" Children like Fabrizio are vocal in their **anxiety** that our dash to **economic** recovery will scupper climate change and **net-zero** **commitments**. They continue to pressure us all for urgency, and to fight for a green recovery.\r\n\r\n### Final Request and Conclusion\r\nOnce again, Secretary-General, we congratulate you on the **establishment** of the Youth Advisory Group on climate change. We ask, however, that it be **inclusive** of children and **adolescents** younger than 18; respecting their right to be heard and to contribute their **expertise** directly. We also ask that as preparations for COP26 advance, you call for the UK and Italy to give children a safe space to influence these upcoming preparatory events.\r\n\r\nWe would of course be happy to support a process that facilitates meaningful engagement with children across the globe on both your Group and COP26.\r\n\r\nIf the last two years have taught us anything it is that children, armed with information and a sense of purpose, have a unique role to play by participating in decision-making processes and in combating crises with constructive solutions. Let us make sure that we learn and apply this lesson to the planning process related to climate action.\r\n\r\n**Sincerely Yours,**  \r\nSave the Children  \r\nChild Rights Connect\r\n\r\n## 📝 Advanced Vocabulary Development\r\n\r\n### Key Terms with Context\r\n| Word | Pronunciation | Definition | Context Usage |\r\n|------|---------------|------------|---------------|\r\n| **Accelerating** | /əkˈsɛləreɪtɪŋ/ | Making something happen more quickly | Accelerating global climate action |\r\n| **Account** | /əˈkaʊnt/ | Responsibility; being answerable | Holding leaders to account |\r\n| **Activism** | /ˈæktɪvɪzəm/ | Using vigorous campaigning for change | Global climate activism |\r\n| **Adolescent** | /ˌædəˈlɛsənt/ | Young person developing into adult | Children and adolescents under 18 |\r\n| **Agent** | /ˈeɪdʒənt/ | Person taking active role | Agents of change |\r\n| **Anxiety** | /æŋˈzaɪəti/ | Worry about uncertain outcomes | Children\'s anxiety about future |\r\n| **Assert** | /əˈsɜrt/ | State confidently and forcefully | Greta\'s assertion about making difference |\r\n| **Catalyze** | /ˈkatəlʌɪz/ | Cause or accelerate reaction | Catalyze global activism |\r\n| **Commitment** | /kəˈmɪtmənt/ | Dedication to cause or promise | Net-zero commitments |\r\n| **Corporate** | /ˈkɔːpərət/ | Relating to large companies | Corporate leaders |\r\n| **Decision-making** | /dɪˈsɪʒnˌmeɪkɪŋ/ | Process of making important choices | Youth in decision-making |\r\n| **Demonstrate** | /ˈdɛmənstreɪt/ | Show or prove clearly | Demonstrated their outrage |\r\n| **Diversity** | /daɪˈvɜːsɪti/ | Range of different backgrounds | Children in all their diversity |\r\n| **Economic** | /ˌiːkəˈnɒmɪk/ | Relating to economy | Economic recovery |\r\n| **Emphasis** | /ˈɛmfəsɪs/ | Special importance given | Emphasis on frank advice |\r\n| **Engage** | /ɪnˈɡeɪdʒ/ | Participate or become involved | Engaging with leaders |\r\n| **Establishment** | /ɪˈstæblɪʃmənt/ | Action of setting up | Establishment of advisory group |\r\n| **Expertise** | /ˌɛkspɜːˈtiːz/ | Expert knowledge | Children\'s expertise |\r\n| **Frank** | /fræŋk/ | Open, honest, direct | Frank and fearless advice |\r\n| **Global** | /ˈɡləʊbl/ | Relating to whole world | Global climate movement |\r\n| **Inclusive** | /ɪnˈkluːsɪv/ | Including everyone | Inclusive advisory group |\r\n| **Influence** | /ˈɪnflʊəns/ | Capacity to affect others | Channels of influence |\r\n| **Inspiring** | /ɪnˈspɪrɪtɪŋ/ | Uplifting, encouraging | Inspiring solo protest |\r\n\r\n### Climate Change Vocabulary\r\n- **Net-zero**: Achieving balance between greenhouse gas emissions and removal\r\n- **COP26**: 26th UN Climate Change Conference of Parties\r\n- **Green recovery**: Economic recovery prioritizing environmental sustainability\r\n- **Climate crisis**: Urgent global environmental emergency\r\n- **Sustainable environment**: Environment maintained without depletion\r\n\r\n## 📋 Exercise Solutions\r\n\r\n### A.

We also welcome the **emphasis** you place on receiving and giving **frank** and fearless advice, and the urgency of **holding** government and **corporate** leaders to **account** on climate action.\r\n\r\n### The Core Concern\r\nWe are disappointed, however, that you have not expanded this list of young climate leaders to children in all their **diversity**. Millions of children took part in school strikes for climate action in 2019 and early 2020 and **demonstrated** their **outrage** and constructive solutions in equal measure. They have been **agents** of change in the climate debate using their channels of **influence** - schools, social media, and street protest - to **catalyse** **global** **activism** on the climate crisis.\r\n\r\nWe have seen children from the global North to the global South **engaging** with political and corporate leaders - in their home countries and also within the international system - most recently at the UN Human Rights Council - claiming their right to a safe, clean, healthy and sustainable environment as critical foundation to realizing their wellbeing and rights.\r\n\r\n### Youth Leadership Examples\r\nIt was, after all, a child, **Greta Thunberg**, who sparked this global movement through an **inspiring** solo protest in 2018. By 2019, she was able to rightly **assert**: \"We proved that it does not matter what you do and that no one is too small to make a difference.\" In 2020, children are saying the same thing.\r\n\r\nLike **Fabrizio**, a 16-year-old boy from Peru, who told us on a recent child-led online conversation, \"The Future of Children is **at stake** now, tomorrow will be too late.\" Children like Fabrizio are vocal in their **anxiety** that our dash to **economic** recovery will scupper climate change and **net-zero** **commitments**. They continue to pressure us all for urgency, and to fight for a green recovery.\r\n\r\n### Final Request and Conclusion\r\nOnce again, Secretary-General, we congratulate you on the **establishment** of the Youth Advisory Group on climate change. We ask, however, that it be **inclusive** of children and **adolescents** younger than 18; respecting their right to be heard and to contribute their **expertise** directly. We also ask that as preparations for COP26 advance, you call for the UK and Italy to give children a safe space to influence these upcoming preparatory events.\r\n\r\nWe would of course be happy to support a process that facilitates meaningful engagement with children across the globe on both your Group and COP26.\r\n\r\nIf the last two years have taught us anything it is that children, armed with information and a sense of purpose, have a unique role to play by participating in decision-making processes and in combating crises with constructive solutions. Let us make sure that we learn and apply this lesson to the planning process related to climate action.\r\n\r\n**Sincerely Yours,**  \r\nSave the Children  \r\nChild Rights Connect\r\n\r\n## 📝 Advanced Vocabulary Development\r\n\r\n### Key Terms with Context\r\n| Word | Pronunciation | Definition | Context Usage |\r\n|------|---------------|------------|---------------|\r\n| **Accelerating** | /əkˈsɛləreɪtɪŋ/ | Making something happen more quickly | Accelerating global climate action |\r\n| **Account** | /əˈkaʊnt/ | Responsibility; being answerable | Holding leaders to account |\r\n| **Activism** | /ˈæktɪvɪzəm/ | Using vigorous campaigning for change | Global climate activism |\r\n| **Adolescent** | /ˌædəˈlɛsənt/ | Young person developing into adult | Children and adolescents under 18 |\r\n| **Agent** | /ˈeɪdʒənt/ | Person taking active role | Agents of change |\r\n| **Anxiety** | /æŋˈzaɪəti/ | Worry about uncertain outcomes | Children\'s anxiety about future |\r\n| **Assert** | /əˈsɜrt/ | State confidently and forcefully | Greta\'s assertion about making difference |\r\n| **Catalyze** | /ˈkatəlʌɪz/ | Cause or accelerate reaction | Catalyze global activism |\r\n| **Commitment** | /kəˈmɪtmənt/ | Dedication to cause or promise | Net-zero commitments |\r\n| **Corporate** | /ˈkɔːpərət/ | Relating to large companies | Corporate leaders |\r\n| **Decision-making** | /dɪˈsɪʒnˌmeɪkɪŋ/ | Process of making important choices | Youth in decision-making |\r\n| **Demonstrate** | /ˈdɛmənstreɪt/ | Show or prove clearly | Demonstrated their outrage |\r\n| **Diversity** | /daɪˈvɜːsɪti/ | Range of different backgrounds | Children in all their diversity |\r\n| **Economic** | /ˌiːkəˈnɒmɪk/ | Relating to economy | Economic recovery |\r\n| **Emphasis** | /ˈɛmfəsɪs/ | Special importance given | Emphasis on frank advice |\r\n| **Engage** | /ɪnˈɡeɪdʒ/ | Participate or become involved | Engaging with leaders |\r\n| **Establishment** | /ɪˈstæblɪʃmənt/ | Action of setting up | Establishment of advisory group |\r\n| **Expertise** | /ˌɛkspɜːˈtiːz/ | Expert knowledge | Children\'s expertise |\r\n| **Frank** | /fræŋk/ | Open, honest, direct | Frank and fearless advice |\r\n| **Global** | /ˈɡləʊbl/ | Relating to whole world | Global climate movement |\r\n| **Inclusive** | /ɪnˈkluːsɪv/ | Including everyone | Inclusive advisory group |\r\n| **Influence** | /ˈɪnflʊəns/ | Capacity to affect others | Channels of influence |\r\n| **Inspiring** | /ɪnˈspɪrɪtɪŋ/ | Uplifting, encouraging | Inspiring solo protest |\r\n\r\n### Climate Change Vocabulary\r\n- **Net-zero**: Achieving balance between greenhouse gas emissions and removal\r\n- **COP26**: 26th UN Climate Change Conference of Parties\r\n- **Green recovery**: Economic recovery prioritizing environmental sustainability\r\n- **Climate crisis**: Urgent global environmental emergency\r\n- **Sustainable environment**: Environment maintained without depletion\r\n\r\n## 📋 Exercise Solutions\r\n\r\n### A.

COMPLETE EXERCISE SOLUTIONS\r\n\r\n### **2. Answer the following questions:**\r\n\r\n**a. What is gravitation? What are the factors that affect gravitation? Write the SI unit of gravitation.**\r\n\r\n**Answer:** The mutual force of attraction between two bodies is called gravitation.\r\n\r\n**Factors affecting gravitation:**\r\n- Mass of the bodies\r\n- Distance between their centers\r\n\r\n**SI unit:** Newton (N)\r\n\r\n**b. State Newton\'s Universal Law of gravitation.**\r\n\r\n**Answer:** Universal law of gravitation states that \"everybody in this universe attracts another body with a force, which is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centres.\"\r\n\r\n**c. What will happen to the gravitational force between two bodies if the distance between them is halved keeping their masses constant?**\r\n\r\n**Answer:** \r\nGiven: F = Gm₁m₂/d² ... (i)\r\n\r\nIf distance is halved: d₂ = d/2\r\n\r\nNew force: F₂ = Gm₁m₂/(d/2)² = Gm₁m₂/(d²/4) = 4Gm₁m₂/d² ... (ii)\r\n\r\nFrom (i) and (ii): F₂ = 4F\r\n\r\n**Therefore, the gravitational force becomes 4 times greater.**\r\n\r\n**d. What will be the gravitational force between two heavenly bodies if the masses of both are tripled keeping the distance constant?**\r\n\r\n**Answer:**\r\nGiven: F = Gm₁m₂/d² ... (i)\r\n\r\nIf masses are tripled: m₁\' = 3m₁, m₂\' = 3m₂\r\n\r\nNew force: F₂ = G(3m₁)(3m₂)/d² = 9Gm₁m₂/d² ... (ii)\r\n\r\nFrom (i) and (ii): F₂ = 9F\r\n\r\n**Therefore, the gravitational force becomes 9 times greater.**\r\n\r\n**e. What will be the gravitational force between two bodies if the masses of each is doubled and the distance between them is halved?**\r\n\r\n**Answer:**\r\nGiven: F = Gm₁m₂/d² ... (i)\r\n\r\nIf masses are doubled and distance halved:\r\n- m₁\' = 2m₁, m₂\' = 2m₂\r\n- d\' = d/2\r\n\r\nNew force: F₂ = G(2m₁)(2m₂)/(d/2)² = 4Gm₁m₂/(d²/4) = 16Gm₁m₂/d² ... (ii)\r\n\r\nFrom (i) and (ii): F₂ = 16F\r\n\r\n**Therefore, the gravitational force becomes 16 times greater.**\r\n\r\n**f. Define G. Also write its value and SI unit.**\r\n\r\n**Answer:** G is defined as the gravitational force produced between two bodies of unit mass each when they are kept at a unit distance from their center.\r\n\r\n**Value:** 6.67 × 10⁻¹¹ Nm²/kg²\r\n**SI Unit:** Nm²/kg²\r\n\r\n**g. In the formula g = GM/R², what do G, M and R stand for? Prove that g ∝ 1/R².**\r\n\r\n**Answer:** \r\n- G = Gravitational constant\r\n- M = Mass of the Earth\r\n- R = Radius of the Earth\r\n\r\n**Proof:**\r\nLet \'m\' be the mass of an object on Earth\'s surface.\r\n\r\nFrom Newton\'s law: F = GMm/R² ... (i)\r\nFrom Newton\'s second law: F = mg ... (ii)\r\n\r\nEquating (i) and (ii): mg = GMm/R²\r\n\r\nTherefore: g = GM/R²\r\n\r\nSince G and M are constants: g ∝ 1/R²\r\n\r\n**h. What will be the effect on the acceleration due to gravity of the earth if it is compressed to the size of the moon?**\r\n\r\n**Answer:** If Earth is compressed to the size of moon, the acceleration due to gravity will increase because g ∝ 1/R². As radius decreases, g increases.\r\n\r\n**i. The acceleration due to gravity of Jupiter is 25 m/s². What does it mean?**\r\n\r\n**Answer:** It means that if any object is dropped near Jupiter\'s surface, it will accelerate downward at the rate of 25 m/s² due to Jupiter\'s gravity.\r\n\r\n**j. A coin and a feather are dropped in vacuum. Which one will reach the ground first? Why?**\r\n\r\n**Answer:** Both will reach the ground at the same time because in vacuum there is no air resistance, and acceleration due to gravity is same for all objects regardless of their mass.\r\n\r\n**k. Where does a body have more weight - at the pole or at the equator of the earth? Explain with reason.**\r\n\r\n**Answer:** A body has more weight at poles than at equator because polar radius is less than equatorial radius. Since g ∝ 1/R², gravity is stronger at poles, making weight greater.\r\n\r\n**l. When an apple falls towards the earth, the earth moves up to meet the apple. Is this true? If yes, why is the earth\'s motion not noticeable?**\r\n\r\n**Answer:** Yes, it is true according to Newton\'s third law. However, Earth\'s motion is not noticeable because Earth\'s mass is enormously larger than the apple\'s mass, so its acceleration is negligibly small.\r\n\r\n**m. An astronaut is said to be weightless when he travels in a satellite. Does it mean that the earth does not attract him?**\r\n\r\n**Answer:** No, Earth still attracts the astronaut. Weightlessness occurs because both the astronaut and satellite are in free fall together, creating the sensation of zero weight.\r\n\r\n**n. What is the importance of gravitational force? Write any two points.**\r\n\r\n**Answer:**\r\n1. We are able to perform our daily activities due to gravitational force\r\n2. The existence of atmosphere around Earth is possible due to gravitational force\r\n\r\n**o. What is free fall? What happens to the weight of a body when it is falling freely under the action of gravity?**\r\n\r\n**Answer:** When a body falls freely towards Earth\'s center under gravitational influence, the motion is called free fall. During free fall, the apparent weight becomes zero because the body accelerates at g.\r\n\r\n**p. What is the effect of gravity on a falling object? Write the conclusion obtained from the coin and feather experiment.**\r\n\r\n**Answer:** Gravity causes falling objects to accelerate toward Earth. The coin and feather experiment proves that in vacuum, all objects fall at the same rate independent of their masses.\r\n\r\n**q. Write the differences between the fall of a parachute on Earth and its fall on the moon. On what condition does a body have free fall?**\r\n\r\n**Answer:** On Earth, parachute falls slowly due to air resistance and stronger gravity. On moon, it falls faster (no air resistance) but with weaker gravity. \r\n\r\n**Condition for free fall:** When acceleration of body equals acceleration due to gravity.\r\n\r\n**r. Write any two examples of weightlessness.**\r\n\r\n**Answer:**\r\n1. Person in a falling lift\r\n2. Astronauts in satellites\r\n\r\n**s. Define:**\r\n\r\n**i. Acceleration due to gravity:** The acceleration produced on a body due to Earth\'s gravitational force.\r\n\r\n**ii. Weightlessness:** State of a body when it feels no gravitational force acting on it.\r\n\r\n**iii. Free fall:** Motion of a body falling freely under gravity with no external resistance.\r\n\r\n**iv. Null point:** Point between two celestial bodies where net gravitational force is zero.\r\n\r\n---\r\n\r\n### **3. Distinguish between:**\r\n\r\n**a. Gravity and Gravitation**\r\n\r\n| Gravity | Gravitation |\r\n|---------|-------------|\r\n| Force of attraction of Earth on a body | Mutual force of attraction between any two bodies |\r\n| Strong force | Weak force |\r\n| Example: Earth pulls 1kg object with 9.8N | Example: Attraction between books, planets |\r\n\r\n**b.

Give reason:**\r\n\r\n**a. Newton\'s law of gravitation is called a universal law.**\r\n\r\n**Answer:** Because this law applies to all bodies in the universe, from microscopic particles to massive celestial bodies.\r\n\r\n**b. The weight of a body decreases with increase in distance from the earth\'s surface.**\r\n\r\n**Answer:** Because g ∝ 1/R². As distance from Earth increases, value of g decreases, hence weight decreases.\r\n\r\n**c. The weight of a stone is less at the top of a mountain than at its bottom.**\r\n\r\n**Answer:** Because g is greater at bottom (closer to sea level) than at top due to less distance from Earth\'s center.\r\n\r\n**d. The weight of a body is less on the moon than its weight on the earth.**\r\n\r\n**Answer:** Because moon has weaker gravitational force than Earth due to smaller mass and radius.\r\n\r\n**e. The moon has no atmosphere.**\r\n\r\n**Answer:** Because moon\'s gravitational force is too weak to hold gas molecules in its atmosphere.\r\n\r\n**f. The value of g is greater at the poles than at the equator.**\r\n\r\n**Answer:** Because polar radius is smaller than equatorial radius, and g ∝ 1/R².\r\n\r\n**g. There is more role of the moon than the sun to cause tides in oceans.**\r\n\r\n**Answer:** Although sun is more massive, moon is much closer to Earth, making its gravitational effect stronger for causing tides.\r\n\r\n**h. Tides occur in oceans but not in lakes.**\r\n\r\n**Answer:** Because ocean water mass is much larger than lake water, making gravitational effects more noticeable.\r\n\r\n**i. It is difficult to lift a large stone on the surface of the earth but it is easy to lift a small one.**\r\n\r\n**Answer:** Because large stone has more mass, so Earth attracts it with greater gravitational force.\r\n\r\n**j. Mass of Jupiter is 319 times more than Earth but its acceleration due to gravity is only 2.5 times more.**\r\n\r\n**Answer:** Because Jupiter\'s radius is about 11 times larger than Earth\'s, and g ∝ 1/R².\r\n\r\n**k. The weight of a body will be zero during free fall.**\r\n\r\n**Answer:** Because during free fall, the body\'s acceleration equals g, making apparent weight zero.\r\n\r\n**l. A paratrooper does not get injured while jumping from a flying aeroplane.**\r\n\r\n**Answer:** Because parachute increases air resistance, reducing the falling acceleration and impact force.\r\n\r\n**m. When a coin and feather are dropped from a building, the coin reaches ground earlier.**\r\n\r\n**Answer:** Because coin has greater mass and experiences less air resistance compared to feather.\r\n\r\n---\r\n\r\n### **5. Diagrammatic Questions:**\r\n\r\n**1. Earth\'s orbit around sun - gravitational force variation**\r\n\r\n**Answer:** The gravitational force increases as Earth moves from point A to point B because distance to sun is less at B than A, and F ∝ 1/d².\r\n\r\n**2. Feather and coin experiment**\r\n\r\n**a. Name of experiment:** \"Feather and coin\" experiment\r\n\r\n**b. Conclusion:** In vacuum, all objects fall with same acceleration regardless of mass.\r\n\r\n**c. Effect with air:** Coin falls first because it has less air resistance than feather.\r\n\r\n**3.

COMPLETE EXERCISE SOLUTIONS\r\n\r\n### **2. Answer the following questions:**\r\n\r\n**a. What is gravitation? What are the factors that affect gravitation? Write the SI unit of gravitation.**\r\n\r\n**Answer:** The mutual force of attraction between two bodies is called gravitation.\r\n\r\n**Factors affecting gravitation:**\r\n- Mass of the bodies\r\n- Distance between their centers\r\n\r\n**SI unit:** Newton (N)\r\n\r\n**b. State Newton\'s Universal Law of gravitation.**\r\n\r\n**Answer:** Universal law of gravitation states that \"everybody in this universe attracts another body with a force, which is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centres.\"\r\n\r\n**c. What will happen to the gravitational force between two bodies if the distance between them is halved keeping their masses constant?**\r\n\r\n**Answer:** \r\nGiven: F = Gm₁m₂/d² ... (i)\r\n\r\nIf distance is halved: d₂ = d/2\r\n\r\nNew force: F₂ = Gm₁m₂/(d/2)² = Gm₁m₂/(d²/4) = 4Gm₁m₂/d² ... (ii)\r\n\r\nFrom (i) and (ii): F₂ = 4F\r\n\r\n**Therefore, the gravitational force becomes 4 times greater.**\r\n\r\n**d. What will be the gravitational force between two heavenly bodies if the masses of both are tripled keeping the distance constant?**\r\n\r\n**Answer:**\r\nGiven: F = Gm₁m₂/d² ... (i)\r\n\r\nIf masses are tripled: m₁\' = 3m₁, m₂\' = 3m₂\r\n\r\nNew force: F₂ = G(3m₁)(3m₂)/d² = 9Gm₁m₂/d² ... (ii)\r\n\r\nFrom (i) and (ii): F₂ = 9F\r\n\r\n**Therefore, the gravitational force becomes 9 times greater.**\r\n\r\n**e. What will be the gravitational force between two bodies if the masses of each is doubled and the distance between them is halved?**\r\n\r\n**Answer:**\r\nGiven: F = Gm₁m₂/d² ... (i)\r\n\r\nIf masses are doubled and distance halved:\r\n- m₁\' = 2m₁, m₂\' = 2m₂\r\n- d\' = d/2\r\n\r\nNew force: F₂ = G(2m₁)(2m₂)/(d/2)² = 4Gm₁m₂/(d²/4) = 16Gm₁m₂/d² ... (ii)\r\n\r\nFrom (i) and (ii): F₂ = 16F\r\n\r\n**Therefore, the gravitational force becomes 16 times greater.**\r\n\r\n**f. Define G. Also write its value and SI unit.**\r\n\r\n**Answer:** G is defined as the gravitational force produced between two bodies of unit mass each when they are kept at a unit distance from their center.\r\n\r\n**Value:** 6.67 × 10⁻¹¹ Nm²/kg²\r\n**SI Unit:** Nm²/kg²\r\n\r\n**g. In the formula g = GM/R², what do G, M and R stand for? Prove that g ∝ 1/R².**\r\n\r\n**Answer:** \r\n- G = Gravitational constant\r\n- M = Mass of the Earth\r\n- R = Radius of the Earth\r\n\r\n**Proof:**\r\nLet \'m\' be the mass of an object on Earth\'s surface.\r\n\r\nFrom Newton\'s law: F = GMm/R² ... (i)\r\nFrom Newton\'s second law: F = mg ... (ii)\r\n\r\nEquating (i) and (ii): mg = GMm/R²\r\n\r\nTherefore: g = GM/R²\r\n\r\nSince G and M are constants: g ∝ 1/R²\r\n\r\n**h. What will be the effect on the acceleration due to gravity of the earth if it is compressed to the size of the moon?**\r\n\r\n**Answer:** If Earth is compressed to the size of moon, the acceleration due to gravity will increase because g ∝ 1/R². As radius decreases, g increases.\r\n\r\n**i. The acceleration due to gravity of Jupiter is 25 m/s². What does it mean?**\r\n\r\n**Answer:** It means that if any object is dropped near Jupiter\'s surface, it will accelerate downward at the rate of 25 m/s² due to Jupiter\'s gravity.\r\n\r\n**j. A coin and a feather are dropped in vacuum. Which one will reach the ground first? Why?**\r\n\r\n**Answer:** Both will reach the ground at the same time because in vacuum there is no air resistance, and acceleration due to gravity is same for all objects regardless of their mass.\r\n\r\n**k. Where does a body have more weight - at the pole or at the equator of the earth? Explain with reason.**\r\n\r\n**Answer:** A body has more weight at poles than at equator because polar radius is less than equatorial radius. Since g ∝ 1/R², gravity is stronger at poles, making weight greater.\r\n\r\n**l. When an apple falls towards the earth, the earth moves up to meet the apple. Is this true? If yes, why is the earth\'s motion not noticeable?**\r\n\r\n**Answer:** Yes, it is true according to Newton\'s third law. However, Earth\'s motion is not noticeable because Earth\'s mass is enormously larger than the apple\'s mass, so its acceleration is negligibly small.\r\n\r\n**m. An astronaut is said to be weightless when he travels in a satellite. Does it mean that the earth does not attract him?**\r\n\r\n**Answer:** No, Earth still attracts the astronaut. Weightlessness occurs because both the astronaut and satellite are in free fall together, creating the sensation of zero weight.\r\n\r\n**n. What is the importance of gravitational force? Write any two points.**\r\n\r\n**Answer:**\r\n1. We are able to perform our daily activities due to gravitational force\r\n2. The existence of atmosphere around Earth is possible due to gravitational force\r\n\r\n**o. What is free fall? What happens to the weight of a body when it is falling freely under the action of gravity?**\r\n\r\n**Answer:** When a body falls freely towards Earth\'s center under gravitational influence, the motion is called free fall. During free fall, the apparent weight becomes zero because the body accelerates at g.\r\n\r\n**p. What is the effect of gravity on a falling object? Write the conclusion obtained from the coin and feather experiment.**\r\n\r\n**Answer:** Gravity causes falling objects to accelerate toward Earth. The coin and feather experiment proves that in vacuum, all objects fall at the same rate independent of their masses.\r\n\r\n**q. Write the differences between the fall of a parachute on Earth and its fall on the moon. On what condition does a body have free fall?**\r\n\r\n**Answer:** On Earth, parachute falls slowly due to air resistance and stronger gravity. On moon, it falls faster (no air resistance) but with weaker gravity. \r\n\r\n**Condition for free fall:** When acceleration of body equals acceleration due to gravity.\r\n\r\n**r. Write any two examples of weightlessness.**\r\n\r\n**Answer:**\r\n1. Person in a falling lift\r\n2. Astronauts in satellites\r\n\r\n**s. Define:**\r\n\r\n**i.

Give reason:**\r\n\r\n**a. Newton\'s law of gravitation is called a universal law.**\r\n\r\n**Answer:** Because this law applies to all bodies in the universe, from microscopic particles to massive celestial bodies.\r\n\r\n**b. The weight of a body decreases with increase in distance from the earth\'s surface.**\r\n\r\n**Answer:** Because g ∝ 1/R². As distance from Earth increases, value of g decreases, hence weight decreases.\r\n\r\n**c. The weight of a stone is less at the top of a mountain than at its bottom.**\r\n\r\n**Answer:** Because g is greater at bottom (closer to sea level) than at top due to less distance from Earth\'s center.\r\n\r\n**d. The weight of a body is less on the moon than its weight on the earth.**\r\n\r\n**Answer:** Because moon has weaker gravitational force than Earth due to smaller mass and radius.\r\n\r\n**e. The moon has no atmosphere.**\r\n\r\n**Answer:** Because moon\'s gravitational force is too weak to hold gas molecules in its atmosphere.\r\n\r\n**f. The value of g is greater at the poles than at the equator.**\r\n\r\n**Answer:** Because polar radius is smaller than equatorial radius, and g ∝ 1/R².\r\n\r\n**g. There is more role of the moon than the sun to cause tides in oceans.**\r\n\r\n**Answer:** Although sun is more massive, moon is much closer to Earth, making its gravitational effect stronger for causing tides.\r\n\r\n**h. Tides occur in oceans but not in lakes.**\r\n\r\n**Answer:** Because ocean water mass is much larger than lake water, making gravitational effects more noticeable.\r\n\r\n**i. It is difficult to lift a large stone on the surface of the earth but it is easy to lift a small one.**\r\n\r\n**Answer:** Because large stone has more mass, so Earth attracts it with greater gravitational force.\r\n\r\n**j. Mass of Jupiter is 319 times more than Earth but its acceleration due to gravity is only 2.5 times more.**\r\n\r\n**Answer:** Because Jupiter\'s radius is about 11 times larger than Earth\'s, and g ∝ 1/R².\r\n\r\n**k. The weight of a body will be zero during free fall.**\r\n\r\n**Answer:** Because during free fall, the body\'s acceleration equals g, making apparent weight zero.\r\n\r\n**l. A paratrooper does not get injured while jumping from a flying aeroplane.**\r\n\r\n**Answer:** Because parachute increases air resistance, reducing the falling acceleration and impact force.\r\n\r\n**m. When a coin and feather are dropped from a building, the coin reaches ground earlier.**\r\n\r\n**Answer:** Because coin has greater mass and experiences less air resistance compared to feather.\r\n\r\n---\r\n\r\n### **5. Diagrammatic Questions:**\r\n\r\n**1. Earth\'s orbit around sun - gravitational force variation**\r\n\r\n**Answer:** The gravitational force increases as Earth moves from point A to point B because distance to sun is less at B than A, and F ∝ 1/d².\r\n\r\n**2. Feather and coin experiment**\r\n\r\n**a. Name of experiment:** \"Feather and coin\" experiment\r\n\r\n**b. Conclusion:** In vacuum, all objects fall with same acceleration regardless of mass.\r\n\r\n**c. Effect with air:** Coin falls first because it has less air resistance than feather.\r\n\r\n**3.

a coherent system of units.\n* It is a decimal system.\n* It is highly useful in practical and theoretical work.\n\n---\n\n## Dimensional Analysis\n\n* **Dimension:** The power to which the fundamental quantities are raised to express any physical quantity is called dimension.\n* **Dimensional Formula:** The expression of any physical quantity in terms of its basic units.\n* **Dimensional Equation:** An equation containing physical quantities with their dimensional formula is known as a dimensional equation.\n\n**Dimensions of Base Quantities:**\n* Dimension of Mass = $[M]$\n* Dimension of Length = $[L]$\n* Dimension of Time = $[T]$\n* Dimension of Temperature = $[\\theta]$ or $[K]$\n* Dimension of Current = $[A]$ or $[I]$\n\n### Dimensional Formula of Some Physical Quantities\n1.  **Area** = $L \\times b = [L^2] = [M^0L^2T^0]$\n2.  **Volume** = $L \\times b \\times h = [L^3] = [M^0L^3T^0]$\n3.  **Speed** = $\\frac{\\text{distance}}{\\text{time}} = \\frac{L}{T} = [M^0LT^{-1}]$\n4.  **Velocity** = $\\frac{\\text{displacement}}{\\text{time}} = \\frac{L}{T} = [M^0LT^{-1}]$\n5.  **Acceleration** = $\\frac{\\text{change in velocity}}{\\text{time}} = \\frac{LT^{-1}}{T} = [M^0LT^{-2}]$\n6.  **Force** = $m \\times a = [M][LT^{-2}] = [MLT^{-2}]$\n7.  **Density** = $\\frac{m}{V} = \\frac{M}{L^3} = [ML^{-3}T^0]$\n8.  **Surface Tension** = $\\frac{F}{L} = \\frac{MLT^{-2}}{L} = [ML^0T^{-2}]$\n9.  **Impulse** = $F \\times t = [MLT^{-2}][T] = [MLT^{-1}]$\n10. **Momentum** = $m \\times v = [M][LT^{-1}] = [MLT^{-1}]$\n11. **Frequency** = $\\frac{1}{T} = [M^0L^0T^{-1}]$\n12. **Angle** = $\\frac{\\text{arc}}{\\text{radius}} = \\frac{L}{L} = [M^0L^0T^0]$\n13. **Torque / Work** = $F \\cdot d = [MLT^{-2}][L] = [ML^2T^{-2}]$\n14. **Gravitational Constant (G)** = $\\frac{Fd^2}{m_1 m_2} = \\frac{[MLT^{-2}][L^2]}{[M^2]} = [M^{-1}L^3T^{-2}]$\n15. **Specific Heat Capacity** = $[M^0L^2T^{-2}K^{-1}]$\n16. **Power** = $\\frac{W}{t} = \\frac{[ML^2T^{-2}]}{T} =

\\times d^2 = [ML^2T^0]$\n19. **Angular Momentum** = Moment of Inertia $\\times$ Angular Velocity = $[ML^2][T^{-1}] = [ML^2T^{-1}]$\n\n### Principle of Homogeneity\nIt states that the dimensions of each of the terms of a dimensional equation on both sides should be the same. For an equation $z = x + y$, the dimensions of $z$ must be equal to the dimensions of $x$ and $y$.\n\n### Four Categories of Physical Quantities\n1.  **Dimensional Variables:** Physical quantities which have dimensions but do not have a fixed value. (e.g., work, energy)\n2.  **Dimensionless Variables:** Physical quantities which have neither dimensions nor a fixed value. (e.g., strain, specific gravity)\n3.  **Dimensional Constants:** Physical quantities which have dimensions and a fixed value. (e.g., Gravitational constant, velocity of light)\n4.  **Dimensionless Constants:** Quantities which do not possess dimensions but have a fixed value. (e.g., $\\pi$, counting numbers)\n\n---\n\n### Uses of Dimensional Equations\n1.  To check the correctness of a physical relation.\n2.  To derive the relation between various physical quantities.\n3.  To convert the value of a physical quantity from one system of units to another.\n4.  To find the dimension of constants in a given relation.\n\n#### 1. To Check the Correctness of a Physical Relation\n**Example:** Check the correctness of the formula $v^2 = u^2 + 2as$.\n* **LHS Dimension:** $[v^2] = (LT^{-1})^2 = [L^2T^{-2}]$\n* **RHS Dimension:**\n    * For $u^2$: $[u^2] = (LT^{-1})^2 = [L^2T^{-2}]$\n    * For $2as$: $[2as] = [L T^{-2}][L] = [L^2T^{-2}]$ (The constant 2 is dimensionless)\n* Since the dimensions of each term on the LHS and RHS are the same, the formula is dimensionally correct.\n\n#### 2. To Convert Units from One System to Another\nThe measure of a physical quantity is $x = nu$. For two systems, $n_1u_1 = n_2u_2$.\nIf the dimensions are $[M^aL^bT^c]$, then:\n$n_2 = n_1 \\left[ \\frac{M_1}{M_2} \\right]^a \\left[ \\frac{L_1}{L_2} \\right]^b \\left[ \\frac{T_1}{T_2} \\right]^c$\n\n**Example:** Convert 1 Newton (SI) into dyne (CGS).\n* The dimensional formula for Force (F) is $[MLT^{-2}]$. So, $a=1, b=1, c=-2$.\n* **SI System (1):** $n_1=1$, $M_1=1$ kg, $L_1=1$ m, $T_1=1$ s.\n* **CGS System (2):** $n_2=?$, $M_2=1$ g, $L_2=1$ cm, $T_2=1$ s.\n\n$n_2 = 1 \\left[ \\frac{1 \\text{ kg}}{1 \\text{ g}} \\right]^1 \\left[ \\frac{1 \\text{ m}}{1 \\text{ cm}} \\right]^1 \\left[ \\frac{1 \\text{ s}}{1 \\text{ s}} \\right]^{-2}$\n$n_2 = \\left[ \\frac{1000 \\text{ g}}{1 \\text{ g}} \\right] \\left[ \\frac{100 \\text{ cm}}{1 \\text{ cm}} \\right] [1]^{-2}$\n$n_2 = 1000 \\times 100 = 10^5$\nTherefore, **1 Newton = $10^5$ dyne**.\n\n#### 3. To Derive the Relation Between Physical Quantities\n**Example:** Find the formula for the time period (T) of a simple pendulum if it depends upon mass (m), length (l), and acceleration due to gravity (g).\n1.  Assume the relation: $T \\propto m^a l^b g^c$ or $T = k m^a l^b g^c$, where k is a dimensionless constant.\n2.  Write the dimensions for each quantity:\n    $[T] = [M]^a [L]^b [LT^{-2}]^c$\n    $[M^0L^0T^1] = [M^a L^{b+c} T^{-2c}]$\n3.  Equate the powers of M, L, and T by the principle of homogeneity:\n    * For M: $a = 0$\n    * For T: $1 = -2c \\implies c = -1/2$\n    * For L: $0 = b+c \\implies b = -c \\implies b = 1/2$\n4.  Substitute the values of a, b, and c back into the equation:\n    $T = k m^0 l^{1/2} g^{-1/2}$\n    $T = k \\sqrt{\\frac{l}{g}}$\n    (Experimentally, $k=2\\pi$)\n\n### Limitations of Dimensional Analysis\n* It does not give information about dimensionless constants.\n* It does not distinguish between scalar and vector quantities.\n* Formulae cannot be derived if the physical quantity depends upon trigonometric, exponential, or logarithmic functions.\n* A formula cannot be derived if the quantity depends upon more than three factors having dimensions.\n* A formula cannot be derived if the physical relation contains more than one term (e.g., sums or differences).\n\n---\n\n### Other Definitions\n\n* **Precision:** The degree of exactness, which gives the limitation of the measuring instrument.\n* **Accuracy:** The degree to which the observed value approaches the true value.\n* **Significant Figures:** The number of digits in a measurement in which we are reasonably sure.\n\n### Error in Measurement\n* Instrumental error\n* Systematic error\n* Personal error\n* External error\n* Imperfection error\n* Random error\n* Least Count Error\n\n### Notes\n* The SI unit is called a **coherent system** of units because it is based on a set of basic units from which all derived units are obtained by multiplication or division without introducing numerical factors.\n* The SI unit is called a **rational system** of units because it uses only one unit for a given physical quantity. For example, all forms of energy are measured in Joules.\n=== END OF NOTES CONTENT ===', '2025-11-18 14:14:12', '2025-11-18 14:14:37', '2025-11-18 14:14:37', 0, 1, 0.50, 25, '[]', '{}', 'neutral', 0.50, 0.50, 'balanced', 'moderate', 0.50, 0.50, NULL, NULL, NULL),

The letter showcases how children worldwide have become powerful agents of change, sparked by figures like Greta Thunberg.\r\n\r\nThis chapter combines reading comprehension, formal letter analysis, and advanced grammar practice while exploring themes of youth activism, climate justice, and the importance of inclusive decision-making in global governance.\r\n\r\n**Skills Focus:** Formal Letter Analysis, Advanced Reading Comprehension, Reported Speech, Letter Writing  \r\n**Time Required:** 8-10 periods\r\n\r\n## 📚 Learning Objectives\r\nAfter studying this chapter, you will be able to:\r\n- Analyze formal letters and understand their structure and purpose\r\n- Extract key arguments and supporting evidence from advocacy texts\r\n- Understand vocabulary related to climate change, activism, and international organizations\r\n- Master complex reported speech transformations\r\n- Write formal letters to authorities requesting action\r\n- Evaluate the role of youth in global decision-making processes\r\n- Discuss climate change issues and potential solutions\r\n- Apply reading comprehension techniques effectively\r\n\r\n## 📖 Reading Text: Open Letter to UN Secretary-General Antonio Guterres\r\n\r\n### Letter Header and Address\r\n**His Excellency Antonio Guterres**  \r\nUnited Nations Secretary-General  \r\nUnited Nations Secretariat  \r\n42nd Street, New York, NY 10017  \r\n\r\n**Date:** 7 August 2020  \r\n\r\n**RE:** Inclusion of children in the Youth Advisory Group on Climate Change\r\n\r\n### Opening and Congratulations\r\nYour Excellency,\r\n\r\nCongratulations on your recent announcement of seven young climate leaders between the ages of 18 and 28 years old to your **Youth Advisory Group on climate change**, who will advise you regularly on **accelerating** global action and the ambition to **tackle** the worsening climate crisis. We appreciate this important focus on bringing young leaders into **decision-making** and planning processes related to climate action. We also welcome the **emphasis** you place on receiving and giving **frank** and fearless advice, and the urgency of **holding** government and **corporate** leaders to **account** on climate action.\r\n\r\n### The Core Concern\r\nWe are disappointed, however, that you have not expanded this list of young climate leaders to children in all their **diversity**. Millions of children took part in school strikes for climate action in 2019 and early 2020 and **demonstrated** their **outrage** and constructive solutions in equal measure. They have been **agents** of change in the climate debate using their channels of **influence** - schools, social media, and street protest - to **catalyse** **global** **activism** on the climate crisis.\r\n\r\nWe have seen children from the global North to the global South **engaging** with political and corporate leaders - in their home countries and also within the international system - most recently at the UN Human Rights Council - claiming their right to a safe, clean, healthy and sustainable environment as critical foundation to realizing their wellbeing and rights.\r\n\r\n### Youth Leadership Examples\r\nIt was, after all, a child, **Greta Thunberg**, who sparked this global movement through an **inspiring** solo protest in 2018. By 2019, she was able to rightly **assert**: \"We proved that it does not matter what you do and that no one is too small to make a difference.\" In 2020, children are saying the same thing.\r\n\r\nLike **Fabrizio**, a 16-year-old boy from Peru, who told us on a recent child-led online conversation, \"The Future of Children is **at stake** now, tomorrow will be too late.\" Children like Fabrizio are vocal in their **anxiety** that our dash to **economic** recovery will scupper climate change and **net-zero** **commitments**. They continue to pressure us all for urgency, and to fight for a green recovery.\r\n\r\n### Final Request and Conclusion\r\nOnce again, Secretary-General, we congratulate you on the **establishment** of the Youth Advisory Group on climate change. We ask, however, that it be **inclusive** of children and **adolescents** younger than 18; respecting their right to be heard and to contribute their **expertise** directly. We also ask that as preparations for COP26 advance, you call for the UK and Italy to give children a safe space to influence these upcoming preparatory events.\r\n\r\nWe would of course be happy to support a process that facilitates meaningful engagement with children across the globe on both your Group and COP26.\r\n\r\nIf the last two years have taught us anything it is that children, armed with information and a sense of purpose, have a unique role to play by participating in decision-making processes and in combating crises with constructive solutions. Let us make sure that we learn and apply this lesson to the planning process related to climate action.\r\n\r\n**Sincerely Yours,**  \r\nSave the Children  \r\nChild Rights Connect\r\n\r\n## 📝 Advanced Vocabulary Development\r\n\r\n### Key Terms with Context\r\n| Word | Pronunciation | Definition | Context Usage |\r\n|------|---------------|------------|---------------|\r\n| **Accelerating** | /əkˈsɛləreɪtɪŋ/ | Making something happen more quickly | Accelerating global climate action |\r\n| **Account** | /əˈkaʊnt/ | Responsibility; being answerable | Holding leaders to account |\r\n| **Activism** | /ˈæktɪvɪzəm/ | Using vigorous campaigning for change | Global climate activism |\r\n| **Adolescent** | /ˌædəˈlɛsənt/ | Young person developing into adult | Children and adolescents under 18 |\r\n| **Agent** | /ˈeɪdʒənt/ | Person taking active role | Agents of change |\r\n| **Anxiety** | /æŋˈzaɪəti/ | Worry about uncertain outcomes | Children\'s anxiety about future |\r\n| **Assert** | /əˈsɜrt/ | State confidently and forcefully | Greta\'s assertion about making difference |\r\n| **Catalyze** | /ˈkatəlʌɪz/ | Cause or accelerate reaction | Catalyze global activism |\r\n| **Commitment** | /kəˈmɪtmənt/ | Dedication to cause or promise | Net-zero commitments |\r\n| **Corporate** | /ˈkɔːpərət/ | Relating to large companies | Corporate leaders |\r\n| **Decision-making** | /dɪˈsɪʒnˌmeɪkɪŋ/ | Process of making important choices | Youth in decision-making |\r\n| **Demonstrate** | /ˈdɛmənstreɪt/ | Show or prove clearly | Demonstrated their outrage |\r\n| **Diversity** | /daɪˈvɜːsɪti/ | Range of different backgrounds | Children in all their diversity |\r\n| **Economic** | /ˌiːkəˈnɒmɪk/ | Relating to economy | Economic recovery |\r\n| **Emphasis** | /ˈɛmfəsɪs/ | Special importance given | Emphasis on frank advice |\r\n| **Engage** | /ɪnˈɡeɪdʒ/ | Participate or become involved | Engaging with leaders |\r\n| **Establishment** | /ɪˈstæblɪʃmənt/ | Action of setting up | Establishment of advisory group |\r\n| **Expertise** | /ˌɛkspɜːˈtiːz/ | Expert knowledge | Children\'s expertise |\r\n| **Frank** | /fræŋk/ | Open, honest, direct | Frank and fearless advice |\r\n| **Global** | /ˈɡləʊbl/ | Relating to whole world | Global climate movement |\r\n| **Inclusive** | /ɪnˈkluːsɪv/ | Including everyone | Inclusive advisory group |\r\n| **Influence** | /ˈɪnflʊəns/ | Capacity to affect others | Channels of influence |\r\n| **Inspiring** | /ɪnˈspɪrɪtɪŋ/ | Uplifting, encouraging | Inspiring solo protest |\r\n\r\n### Climate Change Vocabulary\r\n- **Net-zero**: Achieving balance between greenhouse gas emissions and removal\r\n- **COP26**: 26th UN Climate Change Conference of Parties\r\n- **Green recovery**: Economic recovery prioritizing environmental sustainability\r\n- **Climate crisis**: Urgent global environmental emergency\r\n- **Sustainable environment**: Environment maintained without depletion\r\n\r\n## 📋 Exercise Solutions\r\n\r\n### A.

They have been **agents** of change in the climate debate using their channels of **influence** - schools, social media, and street protest - to **catalyse** **global** **activism** on the climate crisis.\r\n\r\nWe have seen children from the global North to the global South **engaging** with political and corporate leaders - in their home countries and also within the international system - most recently at the UN Human Rights Council - claiming their right to a safe, clean, healthy and sustainable environment as critical foundation to realizing their wellbeing and rights.\r\n\r\n### Youth Leadership Examples\r\nIt was, after all, a child, **Greta Thunberg**, who sparked this global movement through an **inspiring** solo protest in 2018. By 2019, she was able to rightly **assert**: \"We proved that it does not matter what you do and that no one is too small to make a difference.\" In 2020, children are saying the same thing.\r\n\r\nLike **Fabrizio**, a 16-year-old boy from Peru, who told us on a recent child-led online conversation, \"The Future of Children is **at stake** now, tomorrow will be too late.\" Children like Fabrizio are vocal in their **anxiety** that our dash to **economic** recovery will scupper climate change and **net-zero** **commitments**. They continue to pressure us all for urgency, and to fight for a green recovery.\r\n\r\n### Final Request and Conclusion\r\nOnce again, Secretary-General, we congratulate you on the **establishment** of the Youth Advisory Group on climate change. We ask, however, that it be **inclusive** of children and **adolescents** younger than 18; respecting their right to be heard and to contribute their **expertise** directly. We also ask that as preparations for COP26 advance, you call for the UK and Italy to give children a safe space to influence these upcoming preparatory events.\r\n\r\nWe would of course be happy to support a process that facilitates meaningful engagement with children across the globe on both your Group and COP26.\r\n\r\nIf the last two years have taught us anything it is that children, armed with information and a sense of purpose, have a unique role to play by participating in decision-making processes and in combating crises with constructive solutions. Let us make sure that we learn and apply this lesson to the planning process related to climate action.\r\n\r\n**Sincerely Yours,**  \r\nSave the Children  \r\nChild Rights Connect\r\n\r\n## 📝 Advanced Vocabulary Development\r\n\r\n### Key Terms with Context\r\n| Word | Pronunciation | Definition | Context Usage |\r\n|------|---------------|------------|---------------|\r\n| **Accelerating** | /əkˈsɛləreɪtɪŋ/ | Making something happen more quickly | Accelerating global climate action |\r\n| **Account** | /əˈkaʊnt/ | Responsibility; being answerable | Holding leaders to account |\r\n| **Activism** | /ˈæktɪvɪzəm/ | Using vigorous campaigning for change | Global climate activism |\r\n| **Adolescent** | /ˌædəˈlɛsənt/ | Young person developing into adult | Children and adolescents under 18 |\r\n| **Agent** | /ˈeɪdʒənt/ | Person taking active role | Agents of change |\r\n| **Anxiety** | /æŋˈzaɪəti/ | Worry about uncertain outcomes | Children\'s anxiety about future |\r\n| **Assert** | /əˈsɜrt/ | State confidently and forcefully | Greta\'s assertion about making difference |\r\n| **Catalyze** | /ˈkatəlʌɪz/ | Cause or accelerate reaction | Catalyze global activism |\r\n| **Commitment** | /kəˈmɪtmənt/ | Dedication to cause or promise | Net-zero commitments |\r\n| **Corporate** | /ˈkɔːpərət/ | Relating to large companies | Corporate leaders |\r\n| **Decision-making** | /dɪˈsɪʒnˌmeɪkɪŋ/ | Process of making important choices | Youth in decision-making |\r\n| **Demonstrate** | /ˈdɛmənstreɪt/ | Show or prove clearly | Demonstrated their outrage |\r\n| **Diversity** | /daɪˈvɜːsɪti/ | Range of different backgrounds | Children in all their diversity |\r\n| **Economic** | /ˌiːkəˈnɒmɪk/ | Relating to economy | Economic recovery |\r\n| **Emphasis** | /ˈɛmfəsɪs/ | Special importance given | Emphasis on frank advice |\r\n| **Engage** | /ɪnˈɡeɪdʒ/ | Participate or become involved | Engaging with leaders |\r\n| **Establishment** | /ɪˈstæblɪʃmənt/ | Action of setting up | Establishment of advisory group |\r\n| **Expertise** | /ˌɛkspɜːˈtiːz/ | Expert knowledge | Children\'s expertise |\r\n| **Frank** | /fræŋk/ | Open, honest, direct | Frank and fearless advice |\r\n| **Global** | /ˈɡləʊbl/ | Relating to whole world | Global climate movement |\r\n| **Inclusive** | /ɪnˈkluːsɪv/ | Including everyone | Inclusive advisory group |\r\n| **Influence** | /ˈɪnflʊəns/ | Capacity to affect others | Channels of influence |\r\n| **Inspiring** | /ɪnˈspɪrɪtɪŋ/ | Uplifting, encouraging | Inspiring solo protest |\r\n\r\n### Climate Change Vocabulary\r\n- **Net-zero**: Achieving balance between greenhouse gas emissions and removal\r\n- **COP26**: 26th UN Climate Change Conference of Parties\r\n- **Green recovery**: Economic recovery prioritizing environmental sustainability\r\n- **Climate crisis**: Urgent global environmental emergency\r\n- **Sustainable environment**: Environment maintained without depletion\r\n\r\n## 📋 Exercise Solutions\r\n\r\n### A.

a coherent system of units.\n* It is a decimal system.\n* It is highly useful in practical and theoretical work.\n\n---\n\n## Dimensional Analysis\n\n* **Dimension:** The power to which the fundamental quantities are raised to express any physical quantity is called dimension.\n* **Dimensional Formula:** The expression of any physical quantity in terms of its basic units.\n* **Dimensional Equation:** An equation containing physical quantities with their dimensional formula is known as a dimensional equation.\n\n**Dimensions of Base Quantities:**\n* Dimension of Mass = $[M]$\n* Dimension of Length = $[L]$\n* Dimension of Time = $[T]$\n* Dimension of Temperature = $[\\theta]$ or $[K]$\n* Dimension of Current = $[A]$ or $[I]$\n\n### Dimensional Formula of Some Physical Quantities\n1.  **Area** = $L \\times b = [L^2] = [M^0L^2T^0]$\n2.  **Volume** = $L \\times b \\times h = [L^3] = [M^0L^3T^0]$\n3.  **Speed** = $\\frac{\\text{distance}}{\\text{time}} = \\frac{L}{T} = [M^0LT^{-1}]$\n4.  **Velocity** = $\\frac{\\text{displacement}}{\\text{time}} = \\frac{L}{T} = [M^0LT^{-1}]$\n5.  **Acceleration** = $\\frac{\\text{change in velocity}}{\\text{time}} = \\frac{LT^{-1}}{T} = [M^0LT^{-2}]$\n6.  **Force** = $m \\times a = [M][LT^{-2}] = [MLT^{-2}]$\n7.  **Density** = $\\frac{m}{V} = \\frac{M}{L^3} = [ML^{-3}T^0]$\n8.  **Surface Tension** = $\\frac{F}{L} = \\frac{MLT^{-2}}{L} = [ML^0T^{-2}]$\n9.  **Impulse** = $F \\times t = [MLT^{-2}][T] = [MLT^{-1}]$\n10. **Momentum** = $m \\times v = [M][LT^{-1}] = [MLT^{-1}]$\n11. **Frequency** = $\\frac{1}{T} = [M^0L^0T^{-1}]$\n12. **Angle** = $\\frac{\\text{arc}}{\\text{radius}} = \\frac{L}{L} = [M^0L^0T^0]$\n13. **Torque / Work** = $F \\cdot d = [MLT^{-2}][L] = [ML^2T^{-2}]$\n14. **Gravitational Constant (G)** = $\\frac{Fd^2}{m_1 m_2} = \\frac{[MLT^{-2}][L^2]}{[M^2]} = [M^{-1}L^3T^{-2}]$\n15. **Specific Heat Capacity** = $[M^0L^2T^{-2}K^{-1}]$\n16. **Power** = $\\frac{W}{t} = \\frac{[ML^2T^{-2}]}{T} =

\\times d^2 = [ML^2T^0]$\n19. **Angular Momentum** = Moment of Inertia $\\times$ Angular Velocity = $[ML^2][T^{-1}] = [ML^2T^{-1}]$\n\n### Principle of Homogeneity\nIt states that the dimensions of each of the terms of a dimensional equation on both sides should be the same. For an equation $z = x + y$, the dimensions of $z$ must be equal to the dimensions of $x$ and $y$.\n\n### Four Categories of Physical Quantities\n1.  **Dimensional Variables:** Physical quantities which have dimensions but do not have a fixed value. (e.g., work, energy)\n2.  **Dimensionless Variables:** Physical quantities which have neither dimensions nor a fixed value. (e.g., strain, specific gravity)\n3.  **Dimensional Constants:** Physical quantities which have dimensions and a fixed value. (e.g., Gravitational constant, velocity of light)\n4.  **Dimensionless Constants:** Quantities which do not possess dimensions but have a fixed value. (e.g., $\\pi$, counting numbers)\n\n---\n\n### Uses of Dimensional Equations\n1.  To check the correctness of a physical relation.\n2.  To derive the relation between various physical quantities.\n3.  To convert the value of a physical quantity from one system of units to another.\n4.  To find the dimension of constants in a given relation.\n\n#### 1. To Check the Correctness of a Physical Relation\n**Example:** Check the correctness of the formula $v^2 = u^2 + 2as$.\n* **LHS Dimension:** $[v^2] = (LT^{-1})^2 = [L^2T^{-2}]$\n* **RHS Dimension:**\n    * For $u^2$: $[u^2] = (LT^{-1})^2 = [L^2T^{-2}]$\n    * For $2as$: $[2as] = [L T^{-2}][L] = [L^2T^{-2}]$ (The constant 2 is dimensionless)\n* Since the dimensions of each term on the LHS and RHS are the same, the formula is dimensionally correct.\n\n#### 2. To Convert Units from One System to Another\nThe measure of a physical quantity is $x = nu$. For two systems, $n_1u_1 = n_2u_2$.\nIf the dimensions are $[M^aL^bT^c]$, then:\n$n_2 = n_1 \\left[ \\frac{M_1}{M_2} \\right]^a \\left[ \\frac{L_1}{L_2} \\right]^b \\left[ \\frac{T_1}{T_2} \\right]^c$\n\n**Example:** Convert 1 Newton (SI) into dyne (CGS).\n* The dimensional formula for Force (F) is $[MLT^{-2}]$. So, $a=1, b=1, c=-2$.\n* **SI System (1):** $n_1=1$, $M_1=1$ kg, $L_1=1$ m, $T_1=1$ s.\n* **CGS System (2):** $n_2=?$, $M_2=1$ g, $L_2=1$ cm, $T_2=1$ s.\n\n$n_2 = 1 \\left[ \\frac{1 \\text{ kg}}{1 \\text{ g}} \\right]^1 \\left[ \\frac{1 \\text{ m}}{1 \\text{ cm}} \\right]^1 \\left[ \\frac{1 \\text{ s}}{1 \\text{ s}} \\right]^{-2}$\n$n_2 = \\left[ \\frac{1000 \\text{ g}}{1 \\text{ g}} \\right] \\left[ \\frac{100 \\text{ cm}}{1 \\text{ cm}} \\right] [1]^{-2}$\n$n_2 = 1000 \\times 100 = 10^5$\nTherefore, **1 Newton = $10^5$ dyne**.\n\n#### 3. To Derive the Relation Between Physical Quantities\n**Example:** Find the formula for the time period (T) of a simple pendulum if it depends upon mass (m), length (l), and acceleration due to gravity (g).\n1.  Assume the relation: $T \\propto m^a l^b g^c$ or $T = k m^a l^b g^c$, where k is a dimensionless constant.\n2.  Write the dimensions for each quantity:\n    $[T] = [M]^a [L]^b [LT^{-2}]^c$\n    $[M^0L^0T^1] = [M^a L^{b+c} T^{-2c}]$\n3.  Equate the powers of M, L, and T by the principle of homogeneity:\n    * For M: $a = 0$\n    * For T: $1 = -2c \\implies c = -1/2$\n    * For L: $0 = b+c \\implies b = -c \\implies b = 1/2$\n4.  Substitute the values of a, b, and c back into the equation:\n    $T = k m^0 l^{1/2} g^{-1/2}$\n    $T = k \\sqrt{\\frac{l}{g}}$\n    (Experimentally, $k=2\\pi$)\n\n### Limitations of Dimensional Analysis\n* It does not give information about dimensionless constants.\n* It does not distinguish between scalar and vector quantities.\n* Formulae cannot be derived if the physical quantity depends upon trigonometric, exponential, or logarithmic functions.\n* A formula cannot be derived if the quantity depends upon more than three factors having dimensions.\n* A formula cannot be derived if the physical relation contains more than one term (e.g., sums or differences).\n\n---\n\n### Other Definitions\n\n* **Precision:** The degree of exactness, which gives the limitation of the measuring instrument.\n* **Accuracy:** The degree to which the observed value approaches the true value.\n* **Significant Figures:** The number of digits in a measurement in which we are reasonably sure.\n\n### Error in Measurement\n* Instrumental error\n* Systematic error\n* Personal error\n* External error\n* Imperfection error\n* Random error\n* Least Count Error\n\n### Notes\n* The SI unit is called a **coherent system** of units because it is based on a set of basic units from which all derived units are obtained by multiplication or division without introducing numerical factors.\n* The SI unit is called a **rational system** of units because it uses only one unit for a given physical quantity. For example, all forms of energy are measured in Joules.\n=== END OF NOTES CONTENT ===', '2026-01-26 22:31:35', '2026-01-26 22:32:11', '2026-01-26 22:32:11', 0, 1, 0.50, 35, '[]', '{}', 'neutral', 0.50, 0.50, 'balanced', 'moderate', 0.50, 0.50, NULL, NULL, NULL);

And if the pilot tilts the wing slightly upward (we call that the angle of attack), the wing deflects more air downward, which pushes the wing up harder. But tilt it too much and, well… the air starts getting messy, swirling, and the lift suddenly drops — that’s called a stall.  \n\nIt’s basically a balancing act: speed, angle, and smooth airflow working together.

Those control the nose pointing up or down, tilting left or right, and even sliding side to side in the air.  \n\nThey’re watching the instruments to see speed, altitude, and heading, but they’re also “feeling” the plane — you can tell a lot by the way it responds. If they want to climb, they pull back a little; to turn, they bank the wings; to stay steady, they make tiny adjustments all the time so it’s smooth rather than jerky. A lot of the time in cruise, autopilot helps keep things stable, but the pilot is still ready to take over in a split second if the ride gets bumpy or something changes.  \n\nIt’s kind of like driving a car on ice while following invisible roads in the sky — you’re part driver, part listener, part problem fixer.  \nDoes your brain want to know what happens if the pilot has to handle the plane manually in bad weather?

Specifically, this question is about uniform circular motion, which is a fundamental concept in physics.\n\nTo approach this question, let\'s break it down step by step. Uniform circular motion occurs when an object moves in a circular path at a constant speed. However, to maintain this motion, a force is required, which is known as the centripetal force. This force acts towards the center of the circle and is necessary to keep the object on its circular path.\n\nThe formula for centripetal force is related to the mass of the object, its velocity, and the radius of the circle. Understanding the relationship between these variables is crucial. Generally, the centripetal force is directly proportional to the mass of the object and the square of its velocity, and inversely proportional to the radius of the circle.\n\nWhen examining the options provided, it\'s essential to consider the principles of physics and the mathematical relationships that govern uniform circular motion. You should look for the option that correctly represents these relationships.\n\nTo help you think through this problem, let\'s consider a few key points:\nMass (m): How does the mass of an object affect its motion in a circular path?\nVelocity (v): What role does the velocity of the object play in determining the centripetal force?\nRadius (r): How does the radius of the circular path influence the required centripetal force?\n\nReflecting on these factors and the general principles of physics can guide you toward a deeper understanding of the correct formula for centripetal force.\n\nAdditionally, it might be helpful to think about real-world examples of uniform circular motion, such as a car turning a corner or a satellite orbiting the Earth. Considering how the centripetal force operates in these scenarios can provide insight into the underlying physics.\n\nRemember, the goal is to apply your understanding of the subject matter to select the most appropriate option. Take your time, and carefully consider the relationships between the variables involved in uniform circular motion. \n\nHow would you like to proceed? Would you like to discuss any of the specific options or explore more concepts related to uniform circular motion?', '', '2025-11-02 09:25:01', 2, NULL),

Let\'s take a step back and review the key concepts again.\n\nAs we discussed earlier, centripetal force is necessary to keep an object moving in a circular path. It\'s directed towards the center of the circle and depends on the mass of the object, its velocity, and the radius of the circle.\n\nTo approach this question, let\'s analyze the relationship between these variables. We know that centripetal force is directly proportional to the mass of the object and the square of its velocity. This means that as the mass or velocity increases, the centripetal force also increases.\n\nOn the other hand, the centripetal force is inversely proportional to the radius of the circle. This means that as the radius increases, the centripetal force decreases.\n\nNow, let\'s examine the options provided. We have four different formulas, each with a unique combination of variables. To determine which one is correct, we need to carefully consider the relationships between the variables.\n\nOne way to approach this is to think about the units of each variable. For example, what are the units of mass, velocity, and radius? How do these units relate to the unit of force?\n\nAnother strategy is to consider the physical meaning of each variable. What happens to the centripetal force when the mass of the object increases or decreases? What happens when the velocity increases or decreases?\n\nBy carefully analyzing the relationships between the variables and considering the physical meaning of each option, you should be able to narrow down the possibilities and make an informed decision.\n\nRemember, the goal is not just to choose the correct option, but to understand the underlying principles and concepts that govern uniform circular motion. Take your time, and think critically about each option.\n\nAdditionally, it might be helpful to think about real-world examples of uniform circular motion, such as a car turning a corner or a satellite orbiting the Earth. How do the centripetal forces operate in these scenarios? What factors affect the magnitude of the centripetal force?\n\nBy combining your understanding of the concepts with your analysis of the options, you should be able to make a confident decision.

To evaluate these options, let\'s consider the relationships between the variables involved.\n\nAs we discussed earlier, centripetal force is directly proportional to the mass of the object and the square of its velocity. It\'s also inversely proportional to the radius of the circle. With these relationships in mind, let\'s analyze each option.\n\nOption A suggests that the centripetal force is equal to the mass times the velocity squared, divided by the radius. Option B proposes that the centripetal force is equal to the mass times the radius, divided by the velocity squared. Option C states that the centripetal force is equal to the mass times the velocity squared times the radius. Option D suggests that the centripetal force is equal to the mass divided by the radius times the velocity squared.\n\nNow, let\'s think about the physical meaning of each option.

The content provided is an open letter to UN Secretary-General Antonio Guterres, focusing on the inclusion of children in the Youth Advisory Group on Climate Change. The main point of the letter is to advocate for the meaningful inclusion of young climate activists, specifically those under 18, in international policy discussions on climate change.\n\nThe letter highlights several key points:\nCongratulations on the Youth Advisory Group: The authors appreciate the establishment of the Youth Advisory Group on climate change, which includes young leaders between 18 and 28 years old.\nDisappointment over exclusion: However, they express disappointment that the group does not include children under 18, who have demonstrated significant activism and contribution to the climate debate.\nChildren as agents of change: The letter emphasizes the role of children in sparking global movements, such as Greta Thunberg\'s solo protest, and their ability to influence through schools, social media, and street protests.\nRequest for inclusion: The authors request that the Youth Advisory Group be inclusive of children and adolescents under 18, respecting their right to be heard and contribute their expertise directly.\nCall to action: They also ask for the UK and Italy to provide children with a safe space to influence upcoming COP26 preparatory events and for facilitating meaningful engagement with children globally on climate issues.\n\nGiven this context, when you ask what the content does not want to say, we can infer a few things:\nIt does not want to dismiss the efforts of young people already included in the Youth Advisory Group: The letter acknowledges the importance of the group but seeks to expand its inclusivity.\nIt does not argue against climate action or the importance of addressing climate change: Instead, it emphasizes the need for more inclusive decision-making processes in tackling the climate crisis.\nIt does not suggest that children are incapable of contributing meaningfully to climate discussions: On the contrary, it highlights their capabilities and the importance of their perspectives in finding solutions.\nIt does not propose excluding any current members of the Youth Advisory Group: The request is for expansion and inclusion, not replacement or exclusion.\n\nIn essence, the content is advocating for a more inclusive approach to climate decision-making, valuing the contributions of all individuals, regardless of age, in addressing the global climate crisis.

Let\'s break it down.\n\nAccording to the notes, mass and weight are two distinct concepts in physics. Mass refers to the amount of matter in an object, whereas weight is the force exerted on an object by gravity.\n\nThe notes highlight the key differences between mass and weight:\n\n Mass is a scalar quantity and remains constant everywhere in the universe, whereas weight is a vector quantity that varies with location.\n Mass is measured in kilograms (kg), while weight is measured in Newtons (N).\n* Mass is measured using a beam balance, whereas weight is measured using a spring balance.\n\nThe relationship between mass and weight is given by the formula: Weight = mg, where m is the mass of the object and g is the acceleration due to gravity.\n\nIt\'s essential to understand the distinction between mass and weight, as it\'s a fundamental concept in physics. Can you think of any scenarios where mass and weight might be different? Perhaps we can discuss some examples to help solidify your understanding.', '', '2025-11-02 10:08:54', 2, NULL),

Similarly, when you pull a rope to lift a heavy object, you\'re also applying a force. The force can be either a push or a pull, and it\'s what causes an object to change its state of motion.\n\nThe notes also mention that force is measured in units of Newtons (N), and the SI unit of force is Newton. There\'s also a conversion factor between Newtons and another unit called dyne, where 1 N = 10^5 dynes.\n\nNow, forces can be classified into two types: pulling forces (or attraction forces) and pushing forces (or repulsion forces). For example, when a magnet attracts a piece of iron, it\'s an example of a pulling force. On the other hand, when two like poles of magnets push each other away, it\'s an example of a pushing force.\n\nTo illustrate this further, let\'s consider a simple example. Imagine you\'re playing tug-of-war with your friends. The force you exert on the rope is a pulling force, while the force your friends exert on the rope is also a pulling force, but in the opposite direction. The net force on the rope is the result of both these forces, which determines the motion of the rope.\n\nDoes this explanation help clarify what force means in the context of physics?
