Properties of G
It is independent of nature of masses
It is independent of medium in which the two masses are kept
Properties of Gravitational Forces:
It is independent of the intervening medium between two bodies. It obeys Newton’s 3rd Law i.e. if body A exerts some force on body B then B exerts an equal but opposite force on A. So the force along the line joining the centre of two bodies is central and conservative in nature.
The force of attraction between any two large or small bodies is called gravitation. But if one of these forces happens to be earth then the force of attraction given by the earth on this small body is called gravity.
