Yp Collisions

YP Collisions simulates a two-dimensional collision between two particles. The user chooses the mass, the initial velocity (magnitude and direction), and the coefficient of restitution. An animation shows the motions of the particles before and after the collision, and the following information is displayed: final velocity of each particle, impulse of each particle, momentum (initial and final), percentage of conserved momentum, kinetic energy, percentage of conserved energy. It is also possible to view the force exerted on each particle during the collision. Yves Pelletier pelletier@kagi.com http://www.kagi.com/pelletier
