Topics Covered in  Lakhmir Singh and Manjit Kaur Solutions for Class 9 Physics Chapter 3 Gravitation

Universal Law of Gravitation

According to this Law, every object present in this universe attracts every other object with a force that is proportional to the product of the masses of both the objects and inversely proportional to the square of the distance between them.

Importance of Universal Law of Gravitation

Universal Law of Gravitation explains the various important phenomenons like:

  1. The force which bounds us to the Earth
  2. The motion of Moon around the Earth
  3. The motion of planets around the Sun
  4. The tides which occur due to the Moon and the Sun

Other things that you will learn in the chapter are:

  1. Free Fall
  2. The motion of objects under the influence of the gravitational force of the earth 
  3. Mass
  4. Weight 
  5. Thrust and pressure
  6.  Pressure in fluids 
  7. Buoyancy 
  8. Why objects float or sink when placed on the surface of the water
  9. Archimedes’ Principle
  10. Relative Density
