Question

an oscillatory motion is always periodic but a periodic motion is not always oscillatory explain with an example​

Answer 1

Explanation:

All oscillatory motions are periodic because each oscillations gets completed in a definite interval of time. Eg: On being pulled and then released, a load attached to a spring executes oscillatory motion. On the other hand all periodic motions may Not be oscillatory. for example earth revolves around sun. this is an example of periodic motion but Not of oscillatory motion

pl mark me brainliest if this answer seems helpful to you

Answer 2

Explanation:

An Oscillatory motion is a type of periodic motion which means that is goes back to and fro but for periodic motion it changes after an interval of time. oscillatory motion moves to and fro quickly but the periodic motion has intervals of time before it changes the position again. So the difference is that oscillatory motion moves to and fro quickly but the periodic motion is tedious. The pendulum in the long clocks move side to side in a sort of fast motion and the minute hand in the clock moves only forwards in a circular motion, so a periodic motion is not always oscillatory.
