Comparing gravitational and inertial mass. According to the law of universal gravitation, the attractive force (F) between two bodies is directly proportional to the product of their masses (m1 and m2), and inversely proportional to the square of the distance, r, (inverse-square law) between them. This definition was first done accurately by Henry Cavendish (1731–1810), an English scientist, in 1798, more than 100 years after Newton published his universal law of gravitation. Watch Universal Law of Gravitation in English from Newton's Law of Gravitation here. G is a constant number known as the universal gravitational constant, and the equation itself symbolically summarizes Newton’s universal law of gravitation. The universal law of gravitation states that every particle attracts every other particle in the universe with a force that is directly proportional to the product of the masses and inversely proportional to the square of the distance between them. Newton’s universal law of gravitation equation. Newton’s Law of Gravitation Gravitational force is a attractive force between two masses m 1 and m 2 separated by a distance r.
