universal law of gravitation
states that every particle attracts every other particle in the universe with a force which is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.[note 1] This is a general physical law derived from empirical observations by what Isaac Newton called inductive reasoning.[1] It is a part of classical mechanics and was formulated in Newton's work Philosophiæ Naturalis Principia Mathematica ("the Principia"), first published on 5 July 1687. When Newton presented Book 1 of the unpublished text in April 1686 to the Royal Society, Robert Hooke made a claim that Newton had obtained the inverse square law from him.
In today's language, the law states that every point mass attracts every other point mass by a force acting along the line intersecting the two points. The force is proportional to the product of the two masses, and inversely proportional to the square of the distance between them.[2]
The equation for universal gravitation thus takes the form:
{\displaystyle F=G{\frac {m_{1}m_{2}}{r^{2}}}\ } F=G{\frac {m_{1}m_{2}}{r^{2}}}\
where F is the gravitational force acting between two objects, m1 and m2 are the masses of the objects, r is the distance between
