Best Answer

The gravitational constant was derived experimentally. Until recently, it was believed that it was a universal constant. However, developments in cosmological theories suggest the possibility that it is not a constant.

How do mass and distance effect gravitational force?

The gravitational force between two objects increases with mass: the larger the mass, the stronger the gravitational force. The force decreases with distance between the two objects: the farther apart they are, the weaker the gravitational force.
