Question

An oscillatory motion is always periodic, but a periodic motion is not always oscillatory. Explain with
an example.​

Answer 1

Answer:

Periodic motion is that motion which repeats itself after equal intervals of time. ... A periodic motion may or may not be oscillatory. For example, the motion of planets around the Sun is always periodic but not oscillatory. The motion of the pendulum of a clock is periodic as well as oscillatory.
