What is the definition of gravity?

Gravity is defined as a force that attracts two bodies toward each other. This fundamental force is responsible for the attraction between objects with mass, holding planets in orbit around stars, causing apples to fall to the ground, and giving weight to physical objects. The strength of this gravitational pull is dependent on the masses of the bodies involved and the distance between them, as described by Newton's law of universal gravitation.

In essence, gravity is what keeps celestial bodies in their orbits and is a crucial factor in the structure of the universe. Understanding gravity is essential in fields ranging from physics to astronomy and helps explain a wide range of phenomena, including tidal forces and the behavior of satellites.
