Gravity is a fundamental force of nature that describes the attraction between any two objects possessing mass or energy. This universal force dictates the structure and dynamics of matter on the largest scales, governing everything from the formation of stars and galaxies to the movement of objects on a planet's surface. Its strength is directly related to the amount of mass involved and inversely related to the square of the distance between the objects. Understanding this force is foundational to physics, as it determines the orbits of celestial bodies and influences the behavior of matter in various physical systems.
