The gravitational force between two point masses m 1 and m 2 at separation r is given by F = k m 1 m 1 r 2 . The constant k depends on system of unit only. This is based on:

Acceleration due to gravity in vacuum is same irrespective of size and mass of the body

Acceleration due to gravity in vacuum depends on the mass of the body

There is no acceleration due to gravity in vacuum

In vacuum, there is resistance offered to the motion of the body and this resistance depends on the mass of the body
