The laws of physics cannot be cheated or fooled like the perceptual capabilities of a man can be.

Are you saying that the trajectory of a 90mph fastball released 53.5'-54' from the plate the first 2 feet out of the pitchers hand is different than when it crosses the plate. We've all been behind the plate of a 85-90mph fastball there's no arc.
A 6' pitcher is releasing the ball at about shoulder height, he's coming down off the mound a bit, let's say he releases the ball about 5' above the plate and throwing to the knees 2' above the plate. The trajectory of the ball coming out of the hand is directly to the spot on a downward angle.
The ball is in a downward trajectory, because of our incredible minds and eyes we are able to determine right out of the pitchers hand where the ball should end up at the plate, if not, how could the ball ever be hit.
Now if the ball is coming toward you in a downward trajectory but does not go as low as it should, is it not rising above it's anticipated trajectory?
If the ball because of speed and backspin flattens out a 1/2 degree from it's downward trajectory isn't that for all practical purposes a rise?
