    Here is nice summary - http://hyperphysics.phy-astr.gsu.edu/hbase/shm.html

    More generally - periodic motion - http://hyperphysics.phy-astr.gsu.edu/hbase/permot.html#permot

    Simple harmonic motion implies a linear relationship between a restoring force, which is a function of displacement from some reference location, and acceleration (as opposed to non-linear). Damping may be invovled.

    Without damping the equation of motion is given by a second order differential equation

    [tex] m\ddot{x}\,+\,kx\,=\,0[/itex],

    and the total energy for an undamped oscillator, which is the sum of its kinetic energy and potential energy, is constant.
