Collision

This applet animates the collision of two particles.
It also works out the final velocities, total momentum and kinetic energies.
Please try out by giving any masses and initial velocities.

If the applet does not appear, please try the following:
(1) Download the Java software from www.java.com.
(2) Go to the menu: Tools > Turn off Pop-Up Blocker.

In an elastic collision, both momentum and kinetic energy are conserved.
In an inelastic collision, momentum is conserved but kinetic energy is reduced.
In a completely inelastic collision, the 2 particles stick together after collision.
