In this experiment you will make a simple Foucault pendulum. In which, you will test the effect that various masses of pendulum weights and various lengths of pendulum arms have on the motion of the pendulum. The easiest means to track the progress of the pendulum is to attach a pencil to the end of the various weights used as the pendulum's weight. And allow this to trace the motion of the pendulum over a given length of time, at least 30-60 minutes. After that time, note the path by which the pendulum is swung.
