Question

Are all objects doing oscillatory motion have periodic motion?

• A. True
• B. False

Answer 1

The correct option is A True

The word Oscillatory refers to something that moves back and forth repeatedly. The word Periodic refers to something that repeats after a regular amount of time.Oscillatory motions always repeat after certain interval of time,thus they are periodic but all periodic motion are not oscillatory.Like motion of planets around sun is periodic as because it repeats itself after sometime but cannot be said to perform to and fro motion so they are not oscillatory motion.
