I want to make AS3 top-down racing game. I wrote core code, but now I want to make game more realistic. I need some physics (acceleration, steering, drifting and etc.). Problem is that I suck in physics and math. I need some materials for that stuff if available. Thanks.
Physics engines are around for people like you and myself who 'suck at math'.
As mentioned in comments, Box2D is probably the most well-known and easiest to find tutorials for getting started.
