Pendulum Lab

Education

A pendulum simulator covering three modes: a simple pendulum swinging under gravity, a compound pendulum with real moment of inertia, and a full double pendulum for chaos. The simple pendulum uses the actual nonlinear equation, so large swings visibly depart from the "textbook" period formula. The double-pendulum mode includes a side-by-side "twin" comparison, showing two nearly identical starting angles spiraling into totally different motion.
