Pitching with science

By: Savon Rooker

Question: What do the laws of motion have to do with pitching?

When you pick up a baseball, it immediately suggests its purpose is to be thrown fast and accurate.
When it comes to baseball there is a lot of science that comes to pitching. For the first law of motion I am going to talk about
inertia for baseball pitchers, I learned that, to achieve their full release velocities, baseball pitchers must apply straight-line force from the first movement toward home plate through release. external image 20080331_80452845_33.jpg

The pitcher prepares to do transfer the momentum from his body to the ball. Try throwing a ball without moving your feet it's difficult to throw it very far or very hard, but a forward step makes throwing much easier. So during the windup, the pitcher moves his entire body weight back behind the pitching rubber. Then he thrusts it forward to deliver the pitch.
This movement of momentum from the body to the baseball requires the biomechanical principle called sequential summation of movement. Momentum is the force of movement of a physical object propelling the object to go faster.


The average speed of a pitchers baseball is 90 miles per hour. The ball goes from 0 miles per hour and
accelerates to 90 with tremendous force and velocity. Velocity is the rate of speed at which an action occurs external image braves.jpg
