CBSE Class 11 Physics Chapter 8 - Gravitation

Brief Information: We all know that the objects get attracted to the earth. Thus, everyone is aware of the concepts in gravity and its effects and how it was discovered. However, in class 11 physics, this topic takes you in depths of the concepts related to gravitation. Furthermore, you will get a good grip on the technical basis for gravitation, Kepler’s laws, gravitational law, etc. There are other topics also like Gravitational acceleration, gravity due to earth, gravitational constant, earth satellites potential energy in gravitation, etc that are discussed in this chapter.
