Animated Pendulum
Requires a Wolfram Notebook System
Interact on desktop, mobile and cloud with the free Wolfram Player or other Wolfram Language products.
Use the trigger to animate the pendulum. Change the gravity, pendulum length, maximum angle, and mass to see how they affect motion, period, and energy.

Details
In this Demonstration, all units are in MKS. The numerical solution is accurate and does not use the approximation of replacing by , which is only valid for small angles. Varying the mass changes the area of a disk with a physical density. Kinetic energy is not calculated directly, but from the principle of conservation of energy.
