Gravity is a pulling force that works across space. On Earth gravity pulls objects toward the center of Earth. This is what makes objects fall. It is also what gives an object weight. Weight is a measurement of the force of gravity between an object and the surface it stands on.

How much gravity an object has depends on how big it is. To be specific, how much mass it has. It also depends on how close you are to the object. The closer you are, the stronger the gravity. Why is gravity important? Gravity is very important to our everyday lives. Without Earth's gravity we would fly right off it. We'd all have to be ...
13 Ιουλ 2024 · Gravity, or gravitation, is one of the fundamental forces of the universe. In this article, we discuss it in three parts: Everyday sense: the force which causes objects to fall onto the ground. Newton 's laws: how gravity keeps the Solar System together. Einstein 's theory of general relativity: the role of gravity in the universe.
However, the strength of gravity depends on the size and density of an object – what scientists call its “mass”. The tiny apple’s gravity is too weak to overcome the attraction of the huge Earth, so it falls towards the centre of the planet.
