<P> Newton 's law of universal gravitation states that a particle attracts every other particle in the universe using a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers . This is a general physical law derived from empirical observations by what Isaac Newton called inductive reasoning . 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 's book was presented in 1686 to the Royal Society , Robert Hooke made a claim that Newton had obtained the inverse square law from him . </P>
