Center of percussion

The center of percussion is the point on an extended massive object attached to a pivot where a perpendicular impact will produce no reactive shock at the pivot. Translational and rotational motions cancel at the pivot when an impulsive blow is struck at the center of percussion. The center of percussion is often discussed in the context of a bat, racquet, door, sword or other extended object held at one end. In sports, the center of percussion of a bat or racquet is related to the so-called "sweet spot", but the latter is also related to vibrational bending of the object.
