 P: 3 Do any of you know of a good site, or just a general site, where physics is applied to pinball machines? I 'm having trouble finding any, if there are any out there, that is.
 P: 248 What would you like to know? There is a couple of things about pinball machines related to physics (and by a couple of things I mean, well... everything).
 P: 3 Well, I don't need it in great depth. I'm in an 11th grade Honors Physics class and there is only so much we can cover and understand. Obviously basics is needed. That would be really helpful, thank you. I trust your judgement. If I have any trouble, I'll just yell. :P
 P: 248 Physics and pinball machines I'm guessing you are in Physics C (Mechanics). You should look into Newton's third law (law of conservation). This can represent how the pinball will bounce off of walls. You can also look at impulse momentum equations $$F/delta t = M /delta V$$. This can be applied to when the flipper hits the ball. You can then look at $$d = 1/2gt^2$$. This equation can (when applied on a tilted axis, because the ball is not dropping straight down) provide a distance that the ball will travel downwards in a given amount of time, or you can use the equation $$v_f^2 = v_o^2 + 2ad$$ for the velocity of a ball. Good luck!
 P: 3 That's fantastic. That's just what I needed. Thank you!
