About the Chapter

Gravitation is the third Chapter in Lakhmir Singh’s Class 9 Physics Textbook. In this Chapter, the concept of gravitation has been explained solely to educate students and make them understand the topic thoroughly. Gravitation is an essential subject for those students aspiring to make a career in the field of science. The Chapter explains everything starting from the force of attraction to the mass and weight of the object with formulas. 

In this Chapter, students learn that the earth attracts every object towards itself with the help of the force of attraction.
