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 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 ...

A ball is suspended from a pivot so that it can swing freely. The length of the pendulum is adjustable. For small amplitude, the motion of the pendulum as a function of time is approximately simple ...
