Newton's law of gravitation

The law proposed by Sir Isaac Newton that expresses the force of gravitational attraction between two bodies as a function of their masses and their distance. Expressed mathematically, F = ^Gm1m2/_d² where F is the force in Newtons, m₁ and m₂ are the masses of the bodies in kilograms, G is the gravitational constant, and d is the distance between the bodies in meters.

[After Isaac Newton.]

Newton's law of gravitation

(General Physics) the principle that two particles attract each other with forces directly proportional to the product of their masses divided by the square of the distance between them

Newton's law of gravitation

The principle that two bodies exert a gravitational attraction for each other that increases as their masses increase and as the distance between them decreases. In mathematical terms, the force equals the product of the two masses multiplied by the gravitational constant and divided by the square of the distance. Also called law of gravitation, law of universal gravitation. See Note at gravity.
