Dec 23, 2021 · Gravity is the attraction between two objects that have mass or energy, whether this is seen in dropping a rock from a bridge, a planet orbiting a star or the moon causing ocean tides. Gravity...
Dec 16, 2023 · On the very large scale, as in astronomical systems, the gravitational force is the dominant force determining the motions of moons, planets, stars, and galaxies. The gravitational force also affects the nature of space and time.
As one of the four fundamental forces of nature – alongside electromagnetism and the strong and weak nuclear forces – gravity is a hugely influential natural phenomenon. It’s a property of matter, of stuff. In a nutshell: all matter is attracted to all other matter.
Gravity is most accurately described by the general theory of relativity, proposed by Albert Einstein in 1915, which describes gravity not as a force, but as the curvature of spacetime, caused by the uneven distribution of mass, and causing masses to move along geodesic lines.
Oct 20, 2023 · When considering massive objects (Earth, stars, galaxies), gravity appears to be the most powerful force. However, when you apply gravity to the atomic level, it has little effect because the masses of subatomic particles are so small. On this level, it's actually downgraded to the weakest force.
The most familiar force is gravity. It is responsible for keeping our feet on the ground and holding Earth in its orbit around the Sun. According to the general theory of relativity, gravity can be understood as bends and curves in the fabric of space-time that affect the motions of galaxies, stars, planets, and even light.

5 days ago · 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.
