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 ...

Then the events repeat. And that's simple harmonic motion. There will be a furious few commenters already writing about damping and vectors and Taylor expansions of potential wells and my complete ...
