Question

A particle moves in a circular path with uniform speed. Its motion is
(a) periodic
(b) oscillatory
(c) simple harmonic
(d) angular simple harmonic.

Answer 1

Answer ⇒ Uniform Motion in a circular path is periodic motion, since, object returns to the initial position, after regular intervals of time.

Motion is not oscillatory because there is no to and fro movement.

Since, motion is not oscillatory, it cannot be simple Harmonic Motion. This is because, those motion which are S.H.M. must be oscillatory.

It is not Angular Simple Harmonic Motion motion also, because for angular S.H.M. , Torque must be proportional to the displacement. But it is not so in case of the Circular motion.

Also, Angular S.H.M. is oscillatory motion. But the Circular motion is not so, thus it is not the correct answer.

Therefore, Only Option (a). is correct.
