In this video we will learn about gravity.

  • The ‘g’ is called acceleration due to gravity and its value is set at 9.8 ms-2.
  • On finding the relation between the gravitational constant and the gravity, we get

                                        g = GM/R2

  • The inferences are:

            a) g is directly proportional to the Mass of Earth
            b) g is inversely proportional to the square of the distance between the object and the Earth.

  • If carefully viewed, we may find that g is independent of the mass of the object.
