One of the unintended consequences of all this mound moving talk is breaking balls.
Spin effects are very constant. That is to say that the spin rate on the ball changes very little on the way to the plate whereas the drag on velocity is fairly large. A ball out of the hand at say 90 might only be mid eighties at the plate, whereas 2500 rpm out of the hand will be about 2470 rpm at the plate. And to what end is this important? Acceleration.
Each second the ball is in the air the spin effects accelerate its velocity (think movement) in the spin induced direction.
So all this late break stuff you hear announcers and pundits go on about
is really just the velocity increase based on the constant acceleration caused by the spin effects on the way to the plate. Increase the time in the air by moving the mound back and you increase the velocity of the ball in the spin induced direction. Move the mound back to much and you will see sweeping sliders that start well behind the hitter and end up in the opposite batters box. CB's that start about 6 ft over the hitters head which catch the top of the zone when they come screaming down like a bat out of hell. Slow pitch softball with the ball moving about 80mph straight down anyone ?
Have fun hitting those things you club toting guys.
