Q. The circular motion of a particle with constant speed is :
A) simple harmonic but not periodic
B) periodic and simple harmonic
C) neither periodic nor simple harmonic
D) periodic but not simple harmonic
Explanation
[Solution from source] Uniform circular motion repeats after every revolution, so it is periodic. It is not SHM, because SHM is motion along a line under a restoring force ∝ displacement; only the projection of circular motion is SHM. Answer (4).
