From Yves Pelletier: YP Simple Pendulum simulates a simple pendulum, allowing to study its motion, the forces exerted on it, and its various forms of energy. It is easy tochange the suspended mass, the length of the string and the maximum angle between the string and the vertical. During the animation, up to 6 vectors(tangential velocity, tangential acceleration, centripetal acceleration, total acceleration, weight and tension) and up to 9 graphs (angular position, angularvelocity, tangential velocity, tangential acceleration, centripetal acceleration, total acceleration, forces and energies vs time) can be displayed. The program alsocomputes the period of the pendulum.
