Gravity | Definition, Physics, & Facts | Britannica

Gravity, in mechanics, is the universal force of attraction acting between all bodies of matter. It is by far the weakest force known in nature and thus plays no role in determining the internal properties of everyday matter. Yet, it also controls the trajectories of bodies in the universe and the structure of the whole cosmos.
