SHM period

[physicsss]

Why is the formula for period of simple harmonic motion independent of amplitude?

[Silimay]

The period of simple harmonic motion is time it takes for one full oscillation. Time is independent of amplitude; for instance, SHM with A = 3 and SHM with A = 5 might or might not complete one oscillation in the same amount of time. It just depends on the system, basically.
