Class 9th - Gravitation

Simply Easy Learning

Created by Priyanka Choudhary, Last Updated 19-Aug-2019, Language:English

Description

In this chapter, we will learn about the Universal Law of Gravitation. We will understand how every object in the universe attracts every other object with Gravitational force. We will learn in detail how an object when thrown upwards reaches a certain height and then falls down touching the Earth’s surface.

You will find answers to many questions while you learn in detail about Mass and Weight, the Archimedes’ principle and Buoyancy among the various concepts under Gravitation that we will learn about in this chapter.

Audience

These video lectures have been prepared exclusively for the students of class 9 of English Medium Central Board of Secondary Education, who ought to have a better understanding of the Universal Law of Gravitation.
