Whose law of universal gravitation explained the force between masses?
Quick Answer
Isaac Newton formulated the law of universal gravitation in 1687. It explained why objects fall on Earth and how planets stay in orbit.
The Full Story
Isaac Newton published the law of universal gravitation in Principia in 1687. The law says every mass attracts every other mass, with the force increasing with mass and decreasing with the square of the distance between them. It unified falling bodies on Earth with the motion of the Moon and planets. Newton’s work became one of the foundations of classical physics.
Key Facts
1.Published in 1687 in Principia
