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 ...

For this project I show how to make make a pendulum wave, an interesting science/physics experiment where a series of pendulums is measured so that each one moves slightly faster than the one before ...

Although it's not always so simple to set up, a ballistic pendulum is a perfect tool for introductory physics. The basic idea is to take something that shoots an object (we use a ball launcher, but it ...

[Nicholas Rehm] works during the day at the Applied Physics Laboratory at Johns Hopkins, Maryland, so has considerable experience with a variety of UAV applications. The question arose about how the ...

A basic pendulum is a mass at the end of a string that swings back and forth. It seems simple, and it appears in most introductory physics textbooks. But it's not a trivial problem to solve for the ...

Reaction wheels are useful things, typically used by satellites to keep themselves oriented the right way up in space. Turning the reaction wheel creates an equal and opposite torque in the spacecraft ...
