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 ...
The strike zone is a volume of space, a vertical right pentagonal prism. Its sides are vertical planes extending up from the edges of home plate.The official rules of Major League Baseball, define the top of the strike zone as the midpoint between the top of the batter's shoulders and the top of the uniform pants, and the bottom of the strike zone is at the hollow beneath the kneecap, both ...

[6] The concept of a set batting order is said to have been invented by Alexander Cartwright, who also instituted rules such as the foul ball and tagging the runner (as opposed to pegging him with the ball), and devised the shortstop ...
Hitting mechanics. In baseball, hitting mechanics studies the biomechanical motion that governs the swing of a baseball player.

This includes optimizing a player's swing for either maximizing their "bat speed" or time for ...
