STANDARD Physics Uniform Circular Motion MCQ Question

The circular motion of a particle with constant speed is periodic because it repeats its motion at regular intervals, completing one full revolution in a fixed time. However, it is not simple harmonic motion (SHM) because SHM requires a restoring force proportional to the displacement from an equilibrium position, which is not the case in uniform circular motion. Option A is incorrect as SHM is not exhibited, while option C fails to recognize the periodic nature of circular motion, and option D incorrectly suggests that circular motion can be periodic without being SHM, which is true, but it does not capture the essence of SHM's requirements.
