# Physics Revision Notes for Class 11 Chapter 8 Gravitation

Class 11 Physics Revision Notes Chapter 8 Gravitation consists of all the important theories and explanations related to this chapter. Students will be benefiting from this notes when it comes to getting some clarity with respect to this subject. We are aware of the definition of Gravity:

• Gravity, also called gravitation, is a force that exists among all material objects in the universe. For any two objects or particles having nonzero mass, the force of gravity tends to attract them toward each other
• Some examples of the force of gravity include: The force that holds the gases in the sun. The force that causes a ball you throw in the air to come down again. The force that causes a car to coast downhill even when you aren’t stepping on the gas.

The notes are carefully designed by our subject experts and they are arranged systematically for your convenience. These notes can be referred every time when they face trouble while practicing problems. Having these notes handy will prove to be beneficial. Students will get to learn the definition of various terms such as gravitational potential energy, escape velocity, the gravitational field etc.

## Frequently asked Questions on CBSE Class 11 Physics Notes Chapter 8: Gravitation

Q1

### What does the ‘Law of gravitation’ state?

Newton’s law of gravitation, statement that any particle of matter in the universe attracts any other with a force varying directly as the product of the masses and inversely as the square of the distance between them.

Q2

### What are the disadvantages of ‘Gravity’?

1. Large area modified environment.2. Large energy transmission loss.3. Seasonal variations.

Q3

### What is ‘Escape velocity’?

The minimum velocity that a moving body (such as a rocket) must have to escape from the gravitational field of a celestial body (such as the earth) and move outward into space.
