Bodies once set in motion tend to stay in  

I didn't know this, did you ?

Read first then scroll down !

Theory: Bodies once set in motion tend to stay in motion.

The Problem: 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.

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... see below ...

........Bodies once set in motion
........tend to stay in motion.
