Weight of a fast rotating gyro

  1. Jul 24, 2013 #1
    there is a gyro....

    put it on an electronic scales which has a smooth surface....it shows the weight is M.

    then, let it rotate.... keep increasing the angular velocity....

    will the weight display increase? or else?

    Does its rest energy increase? Where "rest" refers to the center of mass of the object, not to its parts.
    Proper scales measure the rest energy of objects.
