It's America's Pastime. Since 1869, MLB has been the birthplace of American sports. One requirement to be a true American is to have a conceptual understanding of baseball; the seventh inning, "Take Me Out To The Ball Game," as well as hot dogs and warm summer nights at the ballpark are all favorite memories of America's pastime. However, what you may not realize is the extreme physics behind the game. Pitch velocity and the degree to which the ball comes off the bat, exit velocity, and how an outfielder throws are involved in the physics of baseball. It is important to understand the physics involved in baseball to grow in understanding and appreciation of the sport. First of all, the ball on the knuckles. It's called the hardest shot to hit. A pitch that appears to float like a butterfly and then magically drops into the strike zone, stunning the batter and almost always resulting in a strikeout. But how is this presentation actually launched? The name of the pitch essentially implies the way the pitch is thrown, the pitcher squeezes the fingers in the hand, placing the knuckles of the fingers on the ball and releases the ball in this way and manner. But why does it work? It depends on the position of the laces. By throwing the ball from the pitcher's knuckles, the ball shows no spin for the entire duration of the throw. This allows different lift forces within the aerial passes to exert themselves on the ball. In this way, the ball is subjected to different planar motions as a result of the different lift forces that occur on the pitched baseball. In a simplistic explanation, this is why a knuckle ball “ticks” as it is thrown. Second, there's every fan's favorite part of the game, the... center of the card... makes the ball trajectories behave as if they were in a vacuum, not as they would somewhere closer to level of the sea. Finally, another factor that helps increase distance is the absence of humidity. The lack of humidity in Denver's overall climate also encourages greater ball travel distance. Much like the increase in elevation, less humidity means the air isn't as dense, providing fewer molecules for the ball to run into, reducing drag and increasing distances. Upon further investigation, baseball is more than just "One, two, three hits you." you're out,” there's an entire world of physics interacting and practicing the game, invisible to the human eye. So the next time you see a batter hit a home run with a ball on his knuckles at Coors Field in Denver, you'll have a great appreciation for the game physics that came into play on that play..
