A particle travels in a circular path at a uniform speed. Its motion can be described as

Step-by-step solution

A particle moving in a circular path at a uniform speed completes one revolution in a fixed time interval, T = 2 r v . Since the motion repeats itself after equal intervals of time, it is periodic. The motion is not oscillatory because the particle does not move to and fro about a fixed point. Consequently, it is neither simple harmonic nor angular simple harmonic.
