Gravity - Wikipedia
ويبGravity 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).

ويب6 جنوری، 2022 · What is gravity? Gravity is a pulling force (always a force of attraction) between every object in the universe (every bit of matter, everything that has some mass) and every other object. It's a bit like an invisible magnetic pull, but there's no magnetism involved.
What is gravity guide for KS3 physics students - BBC Bitesize
ويبGravity is a force that exists everywhere. It pulls all things with mass or energy toward one another. We commonly experience gravity by being pulled downwards by the Earth.
Gravity - Newton's Law, Universal Force, Mass Attraction
ويبBy 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 between all massive bodies, one that does not require bodily contact and that acts at a …
Introduction to gravity (video) | Khan Academy
ويبIntroduction to gravity. Newton's Law of Universal Gravitation describes the strength of gravitational attraction between two objects. The gravitational force is equal to the mass of object 1 times the mass of object 2, divided by the distance between the objects squared, all times the gravitational constant (G).
