The narrator observed a pendulum in the choir, understanding its isochronal motion was governed by the wire's length and π. A magnetic device beneath the floor ensured its perpetual oscillation by ...

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 ...

A ball is suspended from a pivot so that it can swing freely. The length of the pendulum is adjustable. For small amplitude, the motion of the pendulum as a function of time is approximately simple ...

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 ...
