Welcome!
I'm afraid, there aren't any premade functions that allow physics like box2d as of now. We've had some attempts to build a physics engine and we only got as far as perfect platform collision. But things as rotating sprites according to collision and friction etc. haven't really been created with GE yet.
But I totally agree with you: Physics are an awesome thing to have and why re-create them if there's already tons of engines out there? What one'd have to do would be to apply them and edit all the code. But I don't know if it's that easy. I'm sure if someone of us got around to it (like pyro, hehe, jk, don't read this please) we'd be onto something.
