When the cause of motion is a linear restoring force, the periodic motion is particularly simple and is called simple harmonic motion. This motion has the remarkable property that the period of oscillation is independent of the amplitude of the motion. Complicated periodic motion can always be described in terms of a sum of sines and/or cosines.
