This module expands on the capabilities for teaching using a Pendulum. A pendulum by itself can provide valuable insight into harmonic motion and the relationship between frequency and period. It can ...

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 ...

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: ...
