Question

Why doesn't the moon fall into the earth by its attractive pull?

Answer 1

Earth attracts the moon with the centripetal force.If Earth doesnot attract moon,it goes to other side and misses from its orbit.So,moon always tries to miss its orbit with centrifugal force.Then,centripetal and centrifugal forces are equal,moon is constantly revolving around the earth.If centripetal force is more than centrifugal force,moon fall on the earth.But,it does not do so.

Answer 2

moon is very far from earth. The gravitational force is almost none. So the moon won't fall on earth.
