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 ...

This is a requested post. Clearly, I do requests. The idea here is that I am going to give all the details needed to determine the equation of motion (and then model it) for a basic pendulum. Warning: ...

The Buffalo Museum of Science's impressive 75-foot Foucault pendulum is no longer out of commission, thanks to the efforts of a professor and undergraduate student in UB's Department of Physics. The ...

A Foucault pendulum is a simple device for observing the Earth's rotation. While such pendulums have been around for more than 150 years and are a staple of the modern science museum, they are ...
