Question

A particle is moving in a circle with uniform speed.

Its motion is

(A) periodic and simple harmonic

(B) periodic but not simple harmonic

(C) A periodic

(D) None of the above

Answer 1

(B) periodic but not simple harmonic

Since the motion repeats itself periodically due to constant speed, thus it is periodic motion. But it is not to and fro motion (or SHM) because the acceleration is not dependent on displacement.
