Question

difference between ocilatery and periodic motion​

Answer 1

Answer:

Periodic motion is defined as the motion that repeats itself after fixed intervals of time. ... Oscillatory motion is defined as the to and fro motion of the body about its fixed position.

Answer 2

Answer:

Oscillatory motions are well defined for damped oscillations, simple harmonic oscillations, and for forced oscillations

Periodic motions are abundant in nature

Oscillatory motion is always periodic but a periodic motion may or may not be oscillatory motion. Any motion that repeats itself at regular interval of time is called periodic motion. Examples: Motion of the pendulum of a clock, motion of planets around the Sun, etc.
