Yp Simple Pendulum

YP Simple Pendulum 1.0: Kinematics and dynamics of a simple pendulum. 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 to change 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, angular velocity, tangential velocity, tangential acceleration, centripetal acceleration, total acceleration, forces and energies vs time) can be displayed. The program also computes the period of the pendulum. Price: $20 US System Requirements: YP Simple Pendulum runs on any Macintosh computer with MAC OS 7.0 or later. It needs about 250 Kb on your hard disk and 1 Mb of RAM. Yves Pelletier pelletier@kagi.com http://www.kagi.com/pelletier
