Necessary and sufficient condition for simple harmonic motion. The restoring force must be proportional to the displacement and act opposite to the direction of motion with no drag forces or friction. The frequency of oscillation should not depend on the amplitude.

Is a sufficient condition?

A sufficient condition is a condition or set of conditions that will produce the event.
