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.
