Physics of Baseball Bats- An Analysis

Abstract. An analysis of the physics of baseball bats is presented in this study. The analysis compares the performance of aluminum and wooden baseball bats. Novel experimental approaches to indirectly quantify the performance of these bats have been implemented. The analysis also considers various aspects of baseball including the physical dimensions of the baseball fields, ball exit speed ratio, moment of inertia, trampoline effect, coefficient of restitution and youth baseball. In youth baseball, the baseball bats used are more effective relative to the physical dimensions of the baseball fields. The novelty, in this study, focuses on the investigation of bat and ball collision with the ball immersed in liquid nitrogen. The results seem to suggest that the energy transfer between aluminum bat and liquid nitrogen immersed ball is better than that of wooden bat and immersed ball
