Momentum of centre of mass
WebFigure 7.2.3b depicts the motion of the rod as seen from the perspective of its center of mass. The angular momentum of two small mass elements, each of size dm symmetrically disposed about the center of mass of the rod, is given by = 2rdp = 2rvdm = where is the mass per unit length of the rod. The total relative angular momentum is Web25 sep. 2002 · Spin and center of mass in axially symmetric Einstein–Maxwell spacetimes. C. Kozameh, G. D. Quiroga. Physics. 2012. We give a definition and derive the equations of motion for the center of mass and angular momentum of an axially symmetric, isolated system that emits gravitational and electromagnetic radiation.
