This "magnetic pendulum" uses a motor to set it into motion at a specific speed and angle. Magnets within the pendulum's end and the floor repel one another as the pendulum swings, creating a complex ...

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 ...

The Foucault Pendulum illustrates the rotation of the earth. It is not constrained to stay in a fixed plane like a clock pendulum, but instead its ordinary pendulum motion is free to change direction ...
