Question

Define simple harmonic motion. What are the conditions of SHM?

Answer 1

Simple harmonic motion is a type of where the restoring force is directly proportional to the displacement.
Conditions are:
1)There must be an elastic restoring force acting on the system.
2)The system must have inertia.
3)The acceleration of the system should be directly proportional to its displacement and is always directed to mean position.

Answer 2

Answer:

The motion which gets repeated after some time is called simple harmonic motion

Explanation:

Conditions of SHM :-

(a). particle should perform to and fro motion about a fixed point is called it's mean position.

(b). the acceleration of particle should always be directed towards mean position

(c). the magnitude of the acceleration should be directly proportional to first power of distance of the particle from mean position
