13 juin 2024 · Learn how gravity works as an invisible force that pulls objects toward each other and keeps the planets in orbit around the sun. Explore how gravity affects Earth, light, stars, planets, black holes and more with NASA.
Gravity is the gravitational attraction at the surface of a planet or other celestial body; gravity may also include, in addition to gravitation, the centrifugal force resulting from the planet's rotation (see § Earth's gravity).
21 juin 2024 · Learn about the universal force of attraction acting between all matter, its history, and its effects on celestial and earthly bodies. Explore Newton's and Einstein's theories of gravitation and their implications for physical thought.
6 janv. 2022 · Learn what gravity is, how it works, and how it varies on Earth and in space. Discover the history of gravity, from Aristotle to Einstein, and the challenges of measuring and understanding it.
5 sept. 2023 · Learn about Newton's and Einstein's theories of gravity, and how they explain the force that keeps us grounded and orbits the moon. Explore the latest views on gravity as a particle, wave or distortion of space-time.
30 juil. 2023 · To summarize, according to Einstein, gravity is the curving of spacetime by all the objects in it, combined with the "geodesic" (straight) motions of those objects through the...
Learn how gravity works according to Newton's law, which states that the gravitational force between two objects is proportional to their masses and inversely proportional to the square of the distance between them. See equations, examples, and questions about gravitational field, potential energy, and more.
