So thats simple enough. This law says that every mass exerts an attractive force on every other mass. The force of attraction between them is directly proportional to the product of their masses and inversely proportional to square of distance between them and is represented as F2Gm 1 m 2r2 or Force2GMass 1Mass 2Radius2.
The Law of Universal Gravitation states that the gravitational force between two points of mass is proportional to the magnitudes of their masses and the inverse-square of their separation d.
Newtons law of gravitation statement that any particle of matter in the universe attracts any other with a force varying directly as the product of the masses and inversely as the square of the distance between them. Newton noted that objects at Earths surface hence at a distance of R E R E from the center of Earth have an acceleration of g but the Moon at a distance of about 60 R E 60 R E has a centripetal acceleration about 60 2 60 2 times smaller than g. Newtons Law of Universal 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. Sir Isaac Newton defined this attraction mathematically.
