- Gravity - Wikipedia
Gravity is the word used to describe a physical law, a fundamental physical interaction that derives primarily from mass, and the observed consequences of that interaction on objects Gravity is the law that every object with mass attracts every other object in the universe in proportion to each mass and inversely proportional to the square of the distance between them The force of gravity, F

Gravity is the force by which a planet or other body draws objects toward its center The force of gravity keeps all of the planets in orbit around the sun What else does gravity do? Why do you land on the ground when you jump up instead of floating off into space? Why do things fall down when you throw them or drop them? The answer is gravity: an invisible force that pulls objects toward

Gravity is one of the fundamental forces of nature, governing the motion of celestial bodies, the behavior of objects on Earth, and even the structure of the universe From keeping planets in orbit to pulling apples to the ground, gravity is a force that affects everything with mass But what is gravity, and how does it work?

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
