The Universal Gravitational Constant (G)

(G)The value of G for any pair of masses in the universe is the same.On the other hand its value is independent of the medium in which the masses are placed.This is why the G is called universal gravitational constant.


If m1 and m2 are unit masses and separated by unit distance, then F=G.

Hence, the universal gravitational constant can be defined as the gravitational force between two unit masses which are separated by a unit distance.
