When a person swings a baseball bat and hit a ball with a wooden bat rather than a aluminum bat, it will generally not travel nearly as far. Why is this? This is a concept of momentum on the baseball field. The biggest reason for the ability for a person to hit a ball further with an aluminum bat is because when they do, they are able to swing the accelerate the bat to higher speeds than if they were to use a wooden bat. Momentum is directly proportional to velocity therefore the faster the swing of the bat the further the ball with travel in most cases.
