Question

what are the characteristics of simple harmonic motion

Answer 1

A restoring force must act on the body.
Body must have acceleration in a direction opposite to the displacement and the acceleration must be directly proportional to displacement.
The system must have inertia (mass).
SHM is a type of oscillatory motion.
It is a particular case of periodic motion.
It can be represented by a simple sine or cosine function.

Answer 2

Explanation:

a) The direction of acceleration is always towards the mean position, that is opposite to displacement.

b) Acceleration is directly proportional to displacement.
