FunctionWould be used for various experiments with swinging pendulums. The general usage would be to set one or several pendulums to oscillate over the circular scale at the bottom. The user can the register the amplitude of the swings. In some experiments, such as coupled pendulums or resonance, the amplitude of the swings will vary in time.
