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 ...

At the Houston Museum of Natural Science they recently made a disturbing discovery: their Foucault pendulum had stopped swinging for the first time since its installation in the 1970s. (Video, ...

During Foucalt’s life it was already proven that the Earth rotated, thanks to experiments which showed that weights dropped from tall towers fell slightly to one side rather than straight down. This ...

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 ...

Top 100 Teacher Erika Larkin explains the “pendulum” technique that will improve low-point control, consistency and contact.
