The Effects Of Surface Pace In Baseball, Jason Farlow
The Effects Of Surface Pace In Baseball, Jason Farlow
Senior Theses
A baseball travels across different surfaces at different paces. The goal of this experiment is to find a percentage difference in speeds the ball will reflect off a given surface. The energy lost on the turf surface was far more significant than on dirt surface as the turf lost an average of 26% of its energy as compared to just 16% of the energy on dirt. In the Northwest conference, teams play on four turf-based infields and five dirt-based infields. The results of this study suggest that kinetic friction forces are more significant in reducing ball rebound speed than in …
Effect Of Seam-Height On Curveballs, Joseph S. Carroll
Effect Of Seam-Height On Curveballs, Joseph S. Carroll
Senior Theses
The difference in seam-height between raised and flat-seam baseballs causes them to react differently when thrown by a pitcher. Altering the seam-height on the ball changes the amount of drag force on it as it travels through the air. The goal of this experiment is to measure the difference in vertical deflection between the two types of balls when pitched with curveball topspin. It was discovered that the baseball with raised-seams experiences more vertical deflection than the flat-seam ball.
