The type of force that gravity is classified as is a fundamental force of nature. Specifically, it is described as an attractive force that acts between objects with mass. Gravity is responsible for the attraction of objects toward one another, influencing aspects such as planetary orbits, tidal forces, and the structure of the universe. In physics, it is modeled by Newton's law of universal gravitation and further explained by Einstein's general theory of relativity, which describes gravity as the curvature of spacetime caused by mass.
