Gravity is the gravitational attraction at the surface of a planet or other celestial body; [6] gravity may also include, in addition to gravitation, the centrifugal force resulting from the planet's rotation (see § Earth's gravity).

Why do you land on the ground when you jump up instead of floating off into space? Why do things fall down when you throw them or drop them? 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 desc...
Gravity is what holds the planets in orbitaround the sun and what keeps the moon in orbit around Earth. The gravitational pull of the moon pulls the seas towards it, causing the ocean tides. Gravity creates stars and planets by pulling together the material from which they are made. Gravity not only pulls on mass but also on light. Albert Einstein ...
Gravity is very important to us. We could not live on Earth without it. The sun's gravity keeps Earth in orbit around it, keeping us at a comfortable distance to enjoy the sun's light and warmth. It holds down our atmosphere and the air we need to breathe. Gravity is what holds our world together. However, gravity isn’t the same everywhere on Earth...
Learn how gravity works, what it does, and how it affects us and the universe. Find out about gravity's effects on Earth, the sun, the moon, the planets, the stars, and black holes.
5 days ago · 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.
The strength of this pull depends on the masses of objects at play. Gravity keeps the planets in orbit around the sun and the moon around the Earth. Hence, we define gravity as: Gravity is a force that attracts a body towards the centre of the earth or any other physical body having mass.

Jul 30, 2023 · Gravity: A tool of discovery. The modern description of gravity so accurately predicts how masses interact that it has become a guide for cosmic discoveries.
Gravity is the force that attracts massive objects and shapes the universe. Learn how Newton and Einstein explained it, and what makes it different from other forces.
May 13, 2020 · While gravity's effects can clearly be seen on the scale of things like planets, stars and galaxies, the force of gravity between everyday objects is extremely difficult to measure.
