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.
12 de abr. de 2024 · Newton’s law of gravitation, statement that any particle of matter in the universe attracts any other with a force varying directly as the product of the masses and inversely as the square of the distance between them. Isaac Newton put forward the law in 1687.

Hace 4 días · Gravity or gravitation is a natural phenomenon by which all things with energy are brought toward (or gravitate toward) one another, including stars, planets, galaxies, and even light and sub-atomic particles.
Hace 3 días · Albert Einstein. In physics, theories of gravitation postulate mechanisms of interaction governing the movements of bodies with mass. There have been numerous theories of gravitation since ancient times. The first extant sources discussing such theories are found in ancient Greek philosophy.
11 de abr. de 2024 · Gravity is a fundamental force in nature that causes objects with mass to be attracted to one another. It is the reason why when an individual jumps or falls, they are pulled back to the ground. This force is present everywhere in the universe and plays a crucial role in shaping celestial bodies and governing their movements.
