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: ...

A PENDULUM which is free to swing over a segment of a sphere has possible paths which vary from a rotation resembling an engine governor ball to the swing of a simple pendulum in a plane; which plane ...
