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 ...

In a grandfather clock, a pendulum swings back and forth and this periodic motion is maintained using the energy stored in ...

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 ...

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 ...

French physicist Léon Foucault (1819–1868) is best known for developing the Foucault pendulum, a device that demonstrated once and for all that the Earth rotates. But he was also a master inventor, ...
