In this simple demonstration of how waves work, a Harvard instructor shows how a group of pendulums can move through a complicated dance together — due entirely to the way each pendulum oscillates at ...

Because a pendulum's oscillation frequency depends on its length, not its mass, you can use different colored bowling balls for a pretty effect. By Francie Diep Published Sep 8, 2014 7:20 PM EDT Get ...

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

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 ...

At the time, scientists were aware that the Earth rotated, but this 1851 demo provided easy-to-understand proof. Google's doodle, therefore, lets users manipulate the pendulum, setting the time of day ...

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 ...
