[REQ NAME] software for simple physics simulations

[Monday]

Is there any software or flash program where one can create simple objects and have them interact with simple forces like centrifugal forces, centripetal forces, gravity, etc? for example a wheel rolling, bouncing, or a ball falling, with proper, scientific, calcualted results i.e. action/reaction?

any ideas?

besides novodex rocket demo?
