Interactive Pendulum Lab

A virtual physics laboratory for studying the motion of a simple pendulum. This client-side tool lets you control variables like pendulum length, gravity, and friction (damping) to see how they affect the period and motion. A key feature is the real-time energy chart that visually demonstrates the principle of conservation of energy as it converts between kinetic and potential forms. It's a perfect tool for students learning about oscillations and simple harmonic motion.
