Before I explain and talk about why a ball goes farther when hit with an aluminum bat, I would like to present and explain some vocabulary concept and words. A collision, transfers momentum or kinetic energy from one object to another object. There are two types of collisions, elastic collision and inelastic collision. An elastic collision is a collision that occurs when two objects bounce apart when they collide; the total kinetic energy in the system is the same before and after the collision. For example, elastic collision occurs when equally massive balls move in the same direction; in this case momentum is transferred from one ball to another ball. And an inelastic collision is a collision that occurs when two objects collide and do not bounce away from each other; the collision changes the total kinetic energy in a closed system. For example, inelastic collision occurs when two cars crash and join themselves into one; the objects stick together after colliding. In inelastic c ollision all that happened is the loss of some kinetic energy, objects don not necessarily need to stick together in an inelastic collision. Whether a collision is an elastic collision or inelastic collision momentum would always be the same before and/or after the collision as long as you have a close system. According to Asif Shakur, Chair of Physics and Engineering at Salisbury State University, explains, â€Å"Aluminum is a hard material. It doesn't have a lot of "give." In other words, aluminum is highly elastic. Therefore, very little of the ball's initial kinetic energy (the energy associated with motion) is used up in permanently deforming the aluminum. Indeed, the aluminum springs back quickly and the ball retains much of its initial energy. In co... ...reased the animosity between the two players† (Russell). The point of all of this is that Piazza’s bat broke; professional players typically go through a lot of bats during a baseball season. In conclusion, there are a various numbers of reasons why a ball go farther when hit with an aluminum bat; such as, aluminum bat can be swung faster, aluminum bats have the trampoline effect, aluminum bats have winder sweet spots, and aluminum bats don’t break. A ball goes farther when hit with aluminum bat because of the fact that the bat is very lightweight and have a large 'sweet spot' in which to hit the ball. In order to have a ball with a high speed, in other words, lots of kinetic energy, the collision has to an elastic collision. Aluminum bats can be swung faster because the barrel of an aluminum bat is empty; the distribution of mass along the length of a metal bat.
