Newton's law of universal gravitation

Newton's law of universal gravitation is a scientific law that explains why things pull or push each other. It says that things pull (or attract) each other because of a force called gravity. The bigger something is, the more it pulls or attracts other things - like a big planet pulling objects towards it. The bigger the object, the stronger its gravitational pull will be. This is why planets stay in orbit around the sun, because the sun’s gravitational pull keeps them from moving away.
