NCERT Solutions for Class 9 Science Chapter 10: In chapters 8 and 9 we learned about force and its effects on bodies. We know that a sufficient amount of force is needed to move a body from one point to another. Gravitation is one such force that acts between all the bodies in the universe. The Gravitational force keeps us attached to the surface of the earth.
In this chapter, you will learn all the concepts related to gravitation and to make the learning process fun and easy we have provided the NCERT solutions for the chapter. Through this article, you will be able to download the pdf of the solutions as well as solve the NCERT textbook questions with ease.

CBSE NCERT Solutions For Class 9 Science Chapter 10 – Chapter Description
In this chapter, you will learn about Gravitation and the Universal Law of Gravitation. Initially, the concept of Gravitation will be discussed. This will be followed by the discussion on the Universal Law of Gravitation and its importance with mathematical equations. Later the concepts of free fall, calculation of the value of g, motion of objects under the influence of the gravitational force of the earth will be discussed.
You will also get to know the differences between mass and weight, how to calculate the weight of an object on the Moon. The concepts of Thrust and Pressure will also be discussed. This chapter consists of a lot of numerical which must be understood and practiced diligently. Download solutions to other chapters also by clicking on the below links.
