Simple harmonic motion is typified by the motion of a mass on a spring when it
is subject to the linear elastic restoring force given by Hooke's Law.
The motion is sinusoidal in time and demonstrates a single resonant frequency.
(Simple Harmonic Motion Equations)
The motion equation for simple harmonic motion contains a complete description
of the motion, and other parameters of the motion can be calculated from it.
The velocity and acceleration are given by:
The total energy for an undamped oscillator is the sum of its kinetic energy and
potential energy which is constant at:
Or, simply illustrated graphically below ...
