Detailed Solution

The above statement is True.
Unmoving objects can accelerate even when they have no motion.
Consider an object in motion that is travelling forward. A force suddenly accelerates the thing in the opposite direction. If you watch it, you can see it move ahead for a time, then halt suddenly. The situation will then start to turn around after that. The simple harmonic motion of a spring or a pendulum exhibits this feature as well. After reaching its maximum displacement, the item begins to accelerate in the opposite direction as the restoring force takes over. Even though the object's velocity is zero at this point, it is accelerating slightly to account for the restoring force.
