In physics, gravity (from Latin gravitas 'weight'[1]), also known as gravitation or a gravitational interaction, [2] is a fundamental interaction, which may be described as the effect of a field that is …

Dec 4, 2025 · By his dynamical and gravitational theories, he explained Kepler’s laws and established the modern quantitative science of gravitation. Newton assumed the existence of an attractive force …

13.2: Newton's Law of Universal Gravitation All masses attract one another with a gravitational force proportional to their masses and inversely proportional to the square of the distance between them.

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 …

Mar 4, 2025 · Newton’s law of universal gravitation describes gravity as a force between two masses, decreasing with distance. Einstein’s general theory of relativity redefines gravity as the curvature of …

Jul 19, 2025 · Combining both theories, Newton formulated a universal law of gravitation in the 17th century, which was accurate for every corner of the universe. Newton’s Law of Universal Gravitation …

Sep 25, 2025 · 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 …

There is no terrestrial gravitation for Earth and no celestial gravitation for the planets, but rather a universal gravitation for everything. Every object in the universe attracts every other object in the …

Gravitation is a fundamental force of nature that governs the motion of objects throughout the universe. It is the attractive force that draws two bodies toward one another, resulting in a pull that depends on …

The modern theory of gravitation was formulated by Albert Einstein and is called the general theory of relativity.
