comment Formulas for ball rolling in a bowl?
Thank you! I wish I could know just the half of it, I understand it but don't know to be able to reproduce it again. Your answers despite being so impresive, isn't what I'm looking for, since its calculus consumes high CPU time (cos/sin/square/...), usually for complex calculus it's done by an approach which may not be a real formula based on physics or math laws, but which works as it should. :)

Lets move to the roulette example as Georg said, as it's more clear: It would be like the roulette wheel starting angle, realtive to last spin, so that a spin with a different starting angle and same acceleration/speed would give a different result. About the seconds, yes, I mean it will decelerate according to the seconds remaining :)
