2d dynamics question

  1. Jul 31, 2007 #1
    Well I'm in the process of making a 2d physics engine using Chris Hecker's tutorials and when I read the second one (angular motion) I get confused. I have always thought that when a force is exerted on an object,"part" of the force changes the linear momentum of the object while the "other part" changes the angular momentum. When I read his article, my understanding is that the linear momentum changes according to F=ma and the angular momentum also changes according to the torque induced by that same force. Is that right or am I reading it wrong?
