Question

Assertion (A): Oscillations and vibrations are almost similar. Reason (R): If frequency is small, we call it oscillation and if frequency is very high, we call it vibration.

Assertion (A): Circular motion is a periodic motion, but it is not oscillatory. Reason (R): If the body is given a small displacement from the position, a force comes into play which tries to bring the body back to the equilibrium point, gives rise to oscillatory motion.
