Question

Earth is continuously pulling the moon towards its centre, still, it does not fall to the earth. Why?

Answer 1

Earth is continuously pulling the moon towards its centre, still, it does not fall to the earth because the moon has a tangential velocity. Due to the gravitational force acting on the moon, it changes the direction of motion and it moves in a circular path. If the gravitational force is absent, the moon will just continue moving in a straight line, instead of being in the circular orbit.
