[Stephen Hobley] has been experimenting with an electromagnetic pendulum in order to build himself a clock. Through the course of his experiments, he has learned quite a bit about how pendulums ...

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 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 ...

In the 17th century, Christiaan Huygens, inventor of the pendulum clock, noticed a curious phenomenon. When two identical pendulum clocks are mounted next to each other on a wall, their swings ...

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 ...

Walk into nearly any science museum worth its salt and you're likely to see a Foucault pendulum, a simple but impressive device for observing the Earth's rotation. Such pendulums have been around for ...
