Gravitational force
Solution
- Definition: Gravitational force is a natural force that pulls two objects toward each other. It's the reason why objects fall to the ground on Earth and why planets orbit around the Sun.
- How it Works: The larger the mass of an object, the stronger its gravitational pull. That’s why Earth’s gravity is stronger than the gravity of a small object like a pebble.
- Examples: The force that keeps us from floating into space, The reason planets stay in orbit around the Sun.
- Importance: Gravitational force is essential for maintaining the structure of the universe. Without it, everything would drift apart!

| Mr. Murugan is a farmer. He has a small piece of land and two bulls. He takes good care of his bulls as they help him in farming. Every morning, he takes the bulls for grazing. When it rains he ploughs the land with the bulls. As he has no one to help he starts sowing the seed before sunrise. He irrigates the crop till it grows. He reaps and binds the crop then takes it to thrash the paddy. Finally, with the help of the bulls, he takes the paddy to his house. |

Read the passage below:
| 1. | Our history makes it evident that the Indian Plastics Industry made a vigorous beginning in 1957 but it took more than 30 years for it to pervade Indian lifestyles. In 1979, "the market for plastics' was just being seeded by the state-owned Indian Petro-Chemicals and it was only in 1994 that plastic soft drink bottles became a visible source of annoyance. |
| 2. | In the same year, people in other cities were concerned about the state of public sanitation and also urged regulatory bodies to ban the production, distribution and use of plastic bags. However, the challenge was greater than it appeared at first. |
| 3. |
The massive generation of plastic waste in India is due to rapid urbanisation, spread of retail chains, plastic packaging from grocery to food and vegetable products, to consumer items and cosmetics. The projected high growth rates of GDP and continuing rapid urbanisation suggest that India's trajectory of plastic consumption and plastic waste is likely to increase.
|
| 4. | According to the United Nations Environment Programme (UNEP) report of 2018, India stands among few other countries like France, Mongolia and several African countries that have initiated total or partial nationallevel bans on plastics in their jurisdictions. On World Environment Day in 2018, India vowed to phase out single-use plastics by 2022, which gave a much needed impetus to bring this change |
| 5. | In this context, thereafter ten states (Andhra Pradesh, Chhattisgarh, Gujarat, Himachal Pradesh, Karnataka, Madhya Pradesh, Meghalaya, Odisha, Rajasthan and Tamil Nadu) are currently sending their collected waste to cement plants for co-processing, twelve other states/UTs are using plastic waste for polymer bitumen road construction and still four other states are using the plastic waste for waste-to-energy plants and oil production. A world of greater possibilities has now opened up to initiate appropriate and concrete actions to build up the necessary institutions and systems before oceans turn, irreversibly into a thin soup of plastic. |
| 6. | However there is no one single masterstroke to counter the challenges witnessed by the staggering plastic waste management in the country. The time is now to formulate robust and inclusive National Action Plans and while doing so, the country will establish greater transparency to combat the plastic jeopardy in a more sustainable and holistic way. |
Based on your understanding of the passage answer any six out of the seven questions given below:
- What does the writer mean by 'visible source of annoyance'?
- Why did people demand a ban on plastics?
- What created a demand for plastics in India?
- With reference to the graph write one conclusion that can be drawn about the production of plastics in 2019 (approximately).
- What does the upward trend of the graph indicate?
- What does the line, oceans turning 'irreversibly into a thin soup of plastic', suggest?
- What step must be taken to combat the challenges of plastic waste management? What will be its impact?
