Question

If the apple is attracted by the earths gravitation force then why isn't the earth attracted towards the apple? Mentioned earlier that every object in the universe attracts every other object in universe? Is it because the force of the apple is negligible?

Answer 1

Every object in the Universe attracts every other object in the Universe. Even an apple tugs slightly at everything around it. The strength of gravity depends on the size and density of an object – which is called 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.
