Question

In which condition a harmonic motion becomes a simple harmonic motion?

Answer 1

Simple harmonic motion:

It is the motion of a particle traveling down a straight line with an acceleration that is proportional to the distance from a fixed point on the line and whose magnitude is proportional to the distance from the fixed point.

For a harmonic motion to be accounted for as a simple harmonic motion, the following requirements must be met:

1. With no drag forces or friction, the restoring force must be proportional to the displacement and act in the opposite direction of motion.
2. The amplitude should not affect the frequency of oscillation.
