Gravitational Force
Gravitational force is the natural phenomenon by which physical objects with mass are attracted to each other. It is one of the four fundamental forces in the universe, along with electromagnetic, weak nuclear, and strong nuclear forces. Gravitational force is responsible for keeping planets in orbit around stars, moons around planets, and objects on Earth's surface. This force is described by Isaac Newton's law of universal gravitation and Albert Einstein's theory of general relativity.
