A double one of these devices exhibits chaotic motion. Bullet speed can be calculated with a "ballistic" one of these devices, while a "physical" one has a massive rod. The one of Foucault's demonstrated that the earth rotated, and it is helpful to use the approximation sin theta equals theta for problems involving this system. Exhibiting simple harmonic motion, for 10 points, name this device, the simplest of which is a bob at the end of a string.
