How is center of mass in a complex systems?

  1. Oct 1, 2011 #1
    Now i am suddenly confused with the concept of the center of mass.
    As we know , nucleus are a system of many-body,composed of nucleons. And their interactions are very complex between nucleons. I want to know, If we can observe a nuclei such as Ne20, how is the motivation of its center of mass?

    The position of the center of mass is not affected by the internal motion of the nucleons.
