    "abstract": "It is commonly stated in Newtonian Mechanics that the torque with respect to\nthe laboratory frame is equal to the torque with respect to the center of mass\nframe plus a (R X F) factor, with \"R\" being the position of the center of mass\nand \"F\" denoting the total external force. Although this assertion is true,\nthere is a subtlety in the demonstration that is overlooked in the textbooks.\nIn addition, it is necessary to clarify that if the reference frame attached to\nthe center of mass rotates with respect to certain inertial frame, the\nassertion is not true any more.",
