Frictional force between pool table surface and cue ball?

  1. May 21, 2007 #1
    Hey all,

    i'm doing a physics research on snooker but i don't really know the approximate frictional force acting between the pool table surface (which is made of a wool called baize) and the cue ball. Does anyone know it cos i need to calculate the decceleration of the cue ball as it rolls across the pool table with a certain velocity.

    The best way would probably be to measure it. That in itself would be a good research subject. You could use a small inclined ramp to give the ball a precise amount of kinetic energy and calculate from the distance it rolls (taking into account the moment of inertia and rotational kinetic energy as well as linear kinetic energy...).
