Double Pendulum
A classic example of a chaotic system
The double pendulum is two pendulums linked end to end. The equations are short and completely deterministic, yet the motion is chaotic: change the starting angle by a tenth of a degree and the two paths have nothing in common a few seconds later.
What you can do
- Adjust the initial angles and lengths
- Change the masses and gravity
- Watch the same equations diverge
- See the trajectory and the energy
- Read the model written in Reineur Solver
