Assertion : All oscillatory motions are necessarily periodic motion but all periodic motion are not oscillatory.
Reason : Simple pendulum is an example of oscillatory motion.

All oscillatory motions are necessarily periodic motions but

Define oscillatory motion.

The motion of a simple pendulum is an example of oscillatory motion. ?

Every oscillatory motion is necessarily periodic but every periodic motion need not be oscillatory. Justify.
