Thus the center of mass of the pendulum does not rise to the same height but rather to a lower final height, h, See Figure 11. The total energy lost by the pendulum is equal to its change in potential energy; Total Energy Lost = AU = ng (h, -4) (18) Total Energy Lost = AU = mg/ (1-cose) (19) where / is the distance from the pivot point to the center of mass of the coil wand, and &amp; is the angular position of the coil wand
