Then looking at the dynamics of two low friction surfaces meeting at relatively high pressure (the collision) then force must be transferred to the ball at rest in a downward direction due to the the rotation of the moving ball. It would interesting to run this experiment in a weightless environment. Thanks for the explanation guys.
That sounds like a great idea for a Microgravity University student experiment! Unfortunately, it is a little late for this year's application process, but some one save this idea for next year!
