The famous scientist who formulated the law of gravity is Sir Isaac Newton. In the late 17th century, Newton developed his law of universal gravitation, which posits that every mass attracts every other mass in the universe with a force proportional to the product of their masses and inversely proportional to the square of the distance between them. His groundbreaking work, published in "Philosophiæ Naturalis Principia Mathematica" in 1687, laid the foundation for classical mechanics. Newton's insights into gravitational force revolutionized the understanding of planetary motion and terrestrial phenomena, establishing him as one of history's greatest scientists.
