All oscillatory motions are periodic by nature. Explain.

Define oscillatory motion.

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

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

STATEMENT-1 : An oscillatory motion is necessarily periodic. and STATEMENT -2 : A simple harmonic motion is necessarily osciallatory.

Select the correct statements. (i) A simple harmonic motion is necessarily periodic (ii) A simple harmonic motion is necessarily oscillatory (iii) An oscillatory motion is necessarily periodic (iv) A periodic motion is necessarily oscillatory
