Gravity has an infinite range, although its effects become weaker as objects get farther away. Gravity is described by the general theory of relativity, proposed by Albert Einstein in 1915, which describes gravity in terms of the curvature of spacetime, caused …

Aug 13, 2025 · gravity, in mechanics, the universal force of attraction acting between all bodies of matter. It is by far the weakest known force in nature and thus plays no role in determining the internal properties of everyday matter.

Aug 11, 2025 · The answer is gravity: an invisible force that pulls objects toward each other. Earth's gravity is what keeps you on the ground and what makes things fall. An animation of gravity at work. Albert Einstein described gravity as a curve in space that wraps around an object—such as a star or a planet.

Mar 4, 2025 · Learn what gravity is in physics and astronomy. Get the definition, formulas, and table of gravity on other planets.

Newton’s universal law of gravitation, formulated in his great work of mathematical physics, the Principia, published in 1687, was the first great work of force unification in physics.

Feb 17, 2025 · Gravity, or gravitational attraction, is the tendency of mass to gather toward itself, drifting together even across great distances due to curvature in spacetime. This tendency allows the...

Apr 28, 2025 · Every time you drop a ball, leap into the air, or feel the reassuring weight of your body anchored to the ground, you are experiencing the mysterious phenomenon known as gravity. Gravity is the oldest known force to humanity and yet remains one of the most elusive and profound in all of science.

Jul 30, 2023 · Gravity is one of the universe's fundamental forces and dominates every moment of our conscious experience. It keeps us close to the ground, drags baseballs and basketballs out of the air and...

What is gravity? 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.

Newton's law of universal gravitation describes gravity as a force by stating that every particle attracts every other particle in the universe with a force that is proportional to the product of their masses and inversely proportional to the square of the distance between their centers of mass.
