Baseball centers around the (seemingly) eternal struggle between pitcher and batter, and each uses physics, albeit intuitively, to gain a slim advantage over the other in determining the fate of the game’s center of interest — the ball.
It All Revolves Around The Ball
When you pick up a baseball, it immediately suggests its purpose: to be thrown fast and with considerable accuracy. The pitcher, with his dance-like windup, prepares to do exactly that by transferring momentum from his body to the ball. To appreciate why this is necessary, 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.
