| This is a demonstration of velocity exchange when two
equal masses collide elastically. Consider two balls moving together
colliding with three moving in the opposite direction. The third and fourth
balls exchange velocities, the net effect being that the left going arrow
moves one slot to the left and the right moving arrow one slot to the right.
More exchanges will occur until all left-moving arrows are together on
the left side and all right-moving arrows are together on the right.
This completes the multiple collision and the end result is that two balls
separate on the left and three on the right.
