The rotation of earth about its axis is

A

periodic motion

B

simple harmonic motion

C

periodic but not simple harmonic motion

D

non-periodic motion

Text Solution

Verified by Experts

The rotation of earth about its axis is periodic because it repeats after a regular interval of time.
The rotation of earth about is obviously not a to and fro type of motion about a fixed point, hence its motion is not SHM.
