From Wikipedia, the free encyclopedia.
Simple harmonic motion is the motion of a simple harmonic oscillator, a motion that is neither driven nor damped.
The motion is periodic and can be described as that of a sine function, with constant amplitude. It is characterised by its amplitude and its period.
A motion with period T has frequency f=1/T.
Its importance is that it can serve as a mathematical model of a variety of systems and provides the basis of the characerisation of more complicated motions through the techniques of Fourier analysis.
