Concept

Problem: The Moon does not crash into the Earth because:(a)  the net force on it is zero(b) it is beyond the main pull of the Earth's gravity(c) it is being pulled by the Sun as well as by the Earth(d) it is freely falling but it has a high tangential velocity

FREE Expert Solution

The moon orbits the earth with a high tangential velocity.

In case the orbital speed of the moon becomes zero, it won't rotate around the earth but will fall directly to the earth.
