G1-60 CHAOS - TWO BIFILAR PENDULA

• ID Code: G1-60
• Purpose: Illustrates chaotic motion
• Description: The two pendula are started into apparently identical oscillations, but their motion soon diverges. No matter how closely the motions of the two pendula are started, they eventually must undergo virtually total divergence.

Eric Neumann has created an online simulation that can be used to model one of the legs of the pendulum. Try experimenting with the simulation as well, and see how sensitive it can be to its initial conditions. https://www.myphysicslab.com/pendulum/double-pendulum-en.html
