Double Pendulum Animation

Play with a Double Pendulum. A single pendulum has a repeating pattern, but a double pendulum can behave very chaotically!

This is a good example of a mathematical model. Each unit of time is calculated using the data from the previous unit of time, and the motion you see is the result.

Notes:

• there is a small amount of drag (air resistance)
• at each "restart" the two lengths are altered by a tiny random amount (less than 0.1), and this is enough to make each animation different!
