Be sure to check out the APE physics engine for flash. 

The library contains particles to assign to movieclips that appy the physics.  These base objects can be extended in many ways to create complexity from simplicity.

APE (Actionscript Physics Engine) is an AS3 open source 2D physics engine for use in Flash and Flex. APE is written and maintained by Alec Cove.

CircleParticles
-fixed or non-fixed
-variable mass, elasticity, and surface friction

RectangleParticles
-rotatable
-fixed or non-fixed
-variable mass, elasticity, and surface friction
-corner particles that can be attached to other particles with SpringConstraints

WheelParticles
-traction and angular velocity
-fixed or non-fixed
-variable mass, elasticity, and surface friction
-edge particles that can be attached to other particles with SpringConstraints

SpringConstraints
-stiffness
-collidable or non-collidible
-collidable constraints have variable width and scale

Licensing
-non restrictive LGPL

 [demo]

Hopefully we will have a tutorial soon here using APE and some other excellent libraries released recently with the onslaught of AS3 code and kits that will be fluid in their frequency. Another coming physics library is from polygonal labs called the Motor Engine.
