Pendulum motion presents students with one of the more striking examples of motion which cannot be analysed with the traditional kinematic equations developed in introductory physics courses. Textbooks, such as Giancoli’s Physics: Principles with Applications [1], typically present pendulum motion immediately following simple harmonic motion (SHM). The small-angle ap- proximation is applied and the motion of the sim- ple pendulum is found to undergo, approximately, SHM. That is to say, the pendulum’s restoring force at small angles is directly proportional to its displacement from the equilibrium position, otherwise known as Hooke’s law.
