Newton's law of gravitation

The principle that expresses the force of gravitational attraction between two bodies as a function of their mass and their distance. Expressed mathematically, F = Gm 1 m 2 d ² where F is the force in Newtons, m 1 and m 2 are the masses of the bodies in kilograms, G is the gravitational constant, and d is the distance between the bodies in meters. Newton's Principle of Gravitation is an example of an inverse square law .
