Double Pendulum

Chaos theory in action — Lagrangian mechanics + RK4

• Drag either bob to set initial conditions, release to simulate
• Colored trails trace the chaotic path of the second bob
• Increase pendulum count to see divergence from tiny differences
• Phase space plot (bottom-right) shows ω₂ vs θ₂ attractor
• Adjust gravity, lengths, masses, damping and time speed
