>A consequence of "Every action has an equal and opposite reaction" is the<BR>>conservation of angular momentum.  <BR><BR>This I understand, but we are not talking about a situation where energy is conserved, <BR>we are talking about a system where energy is introduced into the equation via the car <BR>engine.<BR><BR>If this fact makes no difference, and my belief that the forces on a real car add differ <BR>from the forces in my simulation so that rotation of the chassis is either greatly <BR>dampened or non-existant is wrong, would someone mind directly pointing this out to <BR>me? I'm still not persuaded that I'm not just explaining my thoughts badly.<BR><BR>>So, if the wheels of your car start<BR>>turning faster, then the chassis must start rotating in the opposite<BR>>direction.  <BR><BR>I don't see why this is so, since it is not the wheels that suddenly begin turning faster of <BR>their own free will, it is some small part of the chassis (a cog or a flywheel or whateve
 r) <BR>that begins rotating faster. Therefore, could it not be that the wheels are spinning in the <BR>opposite direction in the sense that you mean?<BR><BR>Again, I wish to emphasise that I will be happy to accept that I am wrong (i.e. that my <BR>simulation is already correct, rather than requiring more work), but would really like <BR>someone to make that desperately clear if it is so.<BR><BR>-Thomas<P>When words aren't enough - Vodafone live!
