Question

why is a oscillatory motion always periodic but a periodic motion may not be oscillatory ?

Answer 1

Oscillatory motion is the motion in which a body goes to and forth like in a swing or pendulum. A body in periodic motion repeats its path at certain interval of time. For example, a body in circular motion with constant speed.

One can say that all oscillatory motion are periodic but all periodic motion are not oscillatory.

Hope it is clear to you!!

Best wishes!!
