In baseball, there are many ways to demonstrate physics principles. This is most obvious in pitching. Just by gripping the ball differently, a pitcher can make a ball move in many different ways. An example of this is how a pitcher can throw a curveball, which drops much more than a fastball, and is considerably slower. This is because of the Magnus effect. When a fastball is thrown, it is thrown with backspin, which is not as affected by the Magnus force, allowing the ball to stay up. However, when a ball is thrown with front spin, like with a curveball, the ball rotates away from the direction of the flight which slows the pitch down. The Magnus Force creates a downward force on the ball, causing it to curve.
