Hi guys I have a question. What are the physics involved in roulette? I know you have these: -Spin or momentum of the roulette table -Friction on the ball from the table -wind resistance on the ball -momentum of the ball -And the bounce when the ball finally drops and hits a few groves Anything I've missed? I've placed this in number theory because I was also curious how the maths works. I've been watching some online roulette and keep seeing certain numbers pop up, it looks like more than chance. Is it possible that the ball lands in some places more than others because the guy applying the momentum to the ball is consistent? Kinda like throwing pennies into a cup, if you do it long enough you become consistent due to muscle memory. What do you guys think?
