   2D physics engine (SDL)
  I am currently working on learning SDL so I can do some 2d games, but I need help on the physics side of things so I was wondering if anyone new of some good books or tutorials out there.   
  You should use a popular physics library so that you get familiar with the popular and fairly proven concepts of physics simulations.I think Box2D is a popular choice.You could look here, this sticky topic from this very forum:List of physics engines.;  Box2D is an awesome choice. Highly recommended. I am pretty sure some folks have it running with SDL. Check the forums @ box2d.org   ;  How does Chipmunk compare to Box2D? It's pretty decent too, isn't it?   ;  I think so. But, both have pros and cons. Box2D was one of the inspiratinos for Chipmunk, and some of the code or at least concepts in Box2D are in Chipmunk. Here is another thread, which may be useful:Box2D or Chipmunk...
