Pendulum Motion
Pendulum motion is the movement of a weight swinging freely from a pivot. Wolfram|Alpha provides formulas for calculating this harmonic motion for a large range of pendulum types from double pendulums to torsion pendulums. Wolfram|Alpha includes the equations of motion and Lagrangians for these different systems.
