Once baseballs start moving out of pitchers' gloves, they want to move with constant velocities in straight lines. This wastes force. Curved force applications waste force in two ways. First, they require pitchers to constantly redirect the mass of the baseballs. Second, they take force away from straight-line force applications.
Pitchers apply unbalanced forces that act on baseballs.
Pitchers want to maximize the velocity of their pitches. Therefore, we need to examine what variables influence baseball velocity after force applications at the moment of release, or, release velocity. Substituting these two factors into the law of acceleration formula creates the release velocity formula for baseball pitchers. My uniform acceleration study determined that pitchers apply force from leverage through release for approximately 0.2 seconds. To better understand the interrelationship between release velocities and force and application time, let us assume some other numbers.
