Acceleration can easily be defined as a change in rate or speed. Acceleration can be looked at as a decrease or an increase in velocity/speed of whatever the rate or unit of the object may be. Any object is considered accelerating if it changes velocity at any given point of moving.
In baseball, the pitcher is going to throw the ball across the distance from the mound to home plate. From the moment he throws the ball, the ball is going to start decreasing its acceleration, so by the time the ball reaches the hitters bat, the ball will be at its slowest speed.
Q.) Is the ball moving faster in the process of leaving the pitchers hand, or while it is in the air?
The ball is going to be accelerating quicker as it's leaving the hand of the pitcher because no force is being acted upon it yet to slow it down.
Q.) Suppose the ball leaves the pitchers hand at 95 mph and ends in the glove of the catcher at 76 mph in .4 seconds. What is the balls acceleration?
-47.5 mph
