Vibe:Harmonic Oscillators:Simple Pendulum with Damping

This is a simple pendulum with damping. The damping function used is a velocity-squared damping which simulates air drag. Also, like the regular pendulum this oscillator accounts for the nonlinear performance inherent in large swings.

The regular pendulm (undamped) is described as


The damped pendulum adds a damping factor which is multiplied by (velocity * | velocity |). This squares velocity while allowing the sign to change as the value of velocity changes.
