Center of Percussion - No Force on the Hand
Where at the racquet strings should we meet the ball for the lowest impact on our hand and wrist? The answer is Center of Percussion, aka COP.
According to Wikipedia, "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."
