Higher moments of the force

  1. Dec 22, 2012 #1
    Thinking about Newton's laws, one can see that they concern the force and the torque (the first moment of the force) acting on a particle. That is enough to describe translation and rotation. But, is there something more to this? What about second and higher moment of the force? Is there any obvious reason they don't have any physical meaning?

    They would compress/stretch the object. If you assume rigid objects, they are irrelevant.

    Well that sounds plausible. Thanks for the answer. Can you refer me to the relevant literature?
