Applications of Baseball Models in Slow Pitch Softball

Abstract

 This study addresses the lack of physics-related research in youth slow-pitch softball by contrasting its ball sizes and ways of throwing with baseball, and applying mature physical methods (analysis for bats’ sweet spots, and force-based ball motion modeling). The research aims to provide theoretical support for hitting strategies and to serve for more reasonable training, bridging the gap for this youth-dominated sport. For a home run (60 m from home plate to the outfield edge), the ball needs an initial speed of at least 25.02 m/s, requiring a minimum force of 2502 N with a bat-ball contact time of 0.002 s. Additionally, it is found that hitting near the sweet spot minimizes energy loss from bat vibration, and a launch angle close to 35 degrees above the horizon is optimal for achieving the 60 m range (due to practical force-generation limits). These findings offer practical references for optimizing hitting techniques and training intensity in youth slow-pitch softball.
