You've probably seen the famous pendulum demonstration—the one where the physics professor puts a bowling ball on a rope, holds it by her head, and lets it go, knowing it won't have enough energy to ...

This module expands on the capabilities for teaching using a Pendulum. A pendulum by itself can provide valuable insight into harmonic motion and the relationship between frequency and period. It can ...

A 1-kg mass pendulum is held up to the demonstrator's face and is released. Because of conservation of energy, the mass will not swing higher than the height at which it was released. In fact, because ...

A magnetic mass hangs on the end of a swinging rod. A movable copper plate damps the oscillations. The rod is connected to a rotational motion sensor, which can transmit the data to a computer for ...
