Gravitation Class 11 is an essential chapter for scoring the best grades in your examination. All topics preceding Ch 8 physics class 11 are based on the concepts you’re going to learn from this chapter.

Before starting with Gravitation Class 11, it is crucial to understand that gravity and gravitation are not similar. Gravity is a force that pulls a body to the earth’s centre whereas; gravitation is the force acting between two bodies.

This chapter discusses several important questions, for example, the strength of the gravitational force existing on the earth and moon, Kepler’s law, escape velocity etc.

NCERT Solutions for Class for Class 11 Physics Chapter 8 gives a detailed explanation of the universal law of gravitation and three vital laws proposed by Kepler. It provides you detailed solutions to questions based on escape velocity, acceleration due to gravity and more.

FAQ (Frequently Asked Questions)

1. When Does the Phrase “Weight of the Earth” Make Sense?

Ans. From NCERT Solutions for Class 11 Physics Chapter 8, you can learn that the phrase “weight of the earth” does not mean anything when it’s used in relation to the gravitational field of the earth. It will only be possible to elucidate the earth’s weight by comparing it to the weight of another body. The gravitational force acting between the earth and the body will be able to determine the earth’s weight.

Class 11 Gravitation NCERT solutions do an efficient job in explaining this concept.

2. What are the Three Laws of Kepler?

Ans. The three laws of Kepler are as follows:

  • Law of Orbits

  • Law of Areas

  • Law of Periods

The first law states that all planets move around the sun in an orbit. Law of areas affirms the fact that a straight line connecting a planet and the sun covers equal areas in equal time intervals. The law of periods states that the square of the time taken by the planet to revolve around the sun is co-related to the semi-major axis of its orbit.

3. What is the Universal Law of Gravitation?

Ans.  NCERT Solutions for Class 11 Physics Chapter 8 extensively covers the universal law of gravitation. Newton’s law of gravitation affirms that any particle of matter can be attracted to any other particle with a force which has a direct relation with the product of their masses and an inverse relation with the square of the distance between them.
