- The force that pulls things to the centre of Earth (and other planets) is called gravity. Gravity also holds Earth and the other planets in their orbits around the Sun.

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...
Gravity 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 keeps...
Jan 6, 2022 · 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.
Mar 26, 2016 · On Earth, gravity pulls objects downward toward the center of the Earth. The force of gravity acting on an object is equal to the weight of the object. Of course, other planets have lesser or greater masses than the Earth, so the weight of objects on those planets, and thus the amount of gravitational pull, will be different.
Sep 5, 2023 · Gravity is the force that causes two particles to pull towards each other. Learn about gravity and find out how Newton and Einstein explain gravity.
Sir Isaac Newton came up with one of the heavyweight laws in physics for you: the law of universal gravitation. This law says that every mass exerts an attractive force on every other mass. If the two masses are m1 and m2 and the distance between them is r, the magnitude of the force (F) is.
