Colliding balls

  1. May 8, 2010 #1
    I'm trying to understand how to calculate the collision of two balls e.g. billiard balls.

    I found a java simualtion of colliding balls.
    However I don't understand the equations that were used there.
    The code for calculating the velocity vectors is at

    in the doCollide method.
    The java applet is here

    I don't get what the variable "mag" means? What does mag stand for?
