The gravitational force due to the earth also acts on the moon because of which it revolves around the earth. Similar situation exists for the artificial satellites orbiting the earth. The moon and the artificial satellites orbit the earth. The earth attracts them towards itself but unlike the falling apple,they do not fall on the earth, why?

This because of the velocity of the moon and the satellite along their orbits. If this velocity was not there, they would have fallen on the earth.
