   Collision on an inclined plane
  I'm having trouble getting my head around this problem in a 2D side scroller:I have a wheel moving across a flat surface and it suddenly comes to an incline ( could be constant or curved like a hill). How do i actually get the wheel to start moving up the hill and what happens to the forces acting on the wheel? pseudo code would be appreciated :)http://img153.imageshack.us/img153/9992/wheele.png   
  I would say, make sure you understand how it physically works first before you try to write any code. Try the Math and Physics forum for that.
