Good light weight aabb physics engine

[Firenibbler]

Hello, I have been looking for a good light weight physics engine for simple aabb collision detection, and interaction(solid objects). I cant seem to find anything, the main features I am looking for are:

 

NEEDS:

 

~aabb collision detection

~solid bodies

~gravity

~velocity and accelartion

 

PREFERRED:

 

~ability to rotate the rectangle collisions

~circle collision with rectangles

~take weight into account

 

DON'T WANT:

 

~rendering

~polygon and advanced shape collision  

~other high-level stuff

 

Thank you for your time!

Well the physics extension of Panda.js meets most of your requirements, the rectangle rotating feature is also what I want. So you could take a look at it and write your own since it's not complex at all.
