    The moment of mass of a system of particles is defined in the link below:

    http://en.wikipedia.org/wiki/Center_of_mass

    The moment of mass of a system of particles is equal to the sum of the product of each particle's mass and its distance from an arbitrary reference. At the location of the center of mass, the moment must necessarily be a single number. What is it?
