I am reposting this post because i forgot I had already posted a topic with the same subject, I study physics at uni, but spend my weekends down the casino on the roulette table. I tried to explain to my friend that the reason roulette works is that the centrepetal force of the ball is great than the force exerted by gravity, therefore the ball stays in the wheel. when it is less than the force exerted by gravity it will fall.
but does the wheel spinning in the opposite direction increase the balls centrepetal force. ie if the ball stayed still and the wheel span would there be a centrepetal force on the ball. what are the equations here.
also does all this mean that the ball will always fall out of the wheel at the same speed, because the moment the centrepetal force drops below the gravitaional force it will fall, and the centrepetal force is reliant on the speed.
odd question i know but its irratating me
