CBSE Class 9 Science Chapter 10 - Gravitation Class 9 Notes

Gravitation Class 9 Revision Notes

The chapter of Gravitation in Class 9 Science is an essential chapter which deals in everything related to gravity. Why do you come down when you jump or why does the fruit fall on the ground? This chapter will help you solve these queries with ease. It explores the concept of gravitation in an easy manner. Students are already familiar with the motion of objects and force, the gravitation class 9 notes just further explain the gravitational force.

Other than that, it discusses the motion of objects under the influence of gravitational force on our earth. Similarly, it will help in understanding how the weight of anybody might vary from one place to another. Most importantly, you learn how objects float in liquids. Thus, the Gravitation class 9 notes will come in handy in doing so.
