Particle Dynamics

Interactive modules for the particle dynamics of ECOR 1034: motion along curved paths in rectangular, path and cylindrical coordinates, and the equations of motion. Animated figures draw velocity and acceleration as the motion happens, and every lesson has worked examples and questions with instant feedback.
