Double Pendulum Simulation

In mathematics, in the area of dynamical systems, a double pendulum is a pendulum with another pendulum attached to its end, and is a simple physical system that exhibits rich dynamic behavior. The motion of a double pendulum is governed by a set of coupled ordinary differential equations. For certain energies its motion is chaotic.

This application solves these differential equations using the Runge-Kutta method for the time stepping. 

You can influence the movement of the pendulum by holding your device in different positions.
