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 Add ...

We’re used to seeing pendulum waves generated on tiny scaffolds with itty-bitty balls. But as this awesome demonstration points out, the same physics applies even at the largest scales. The key to ...

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 ...
