A physical pendulum undergoes simple harmonic motion when displaced by a small angle. The oscillations are no longer simple harmonic motion when it is released from a large angle. The pendulum's pivot ...

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 strong permanent magnet acts as a simple pendulum, swinging back and forth while hanging from strings. A copper plate underneath the magnet can be moved up to tune the eddy current damping. Swing ...

Introduction Did you know that playground swings can provide a good lesson in physics—as well as lots of fun? The back-and-forth motion of a swing is an example of a pendulum. We see pendulums in ...
