But this will never lead to sliding or flowing I think...

But that's not the point here. If I have understood you correctly, ball
bearings don't have freedom of movement so it doesn't make sense to talk
about the incoming and outcoming angle... :/

You're right though that the bouncing often continues many many times,
but after the last tiny bounce the ball or particle should still roll or
flow or slide or whatever you want to call it. Did you see that image in
povray.binaries.images I mentioned?
