論文・フォークボールの不思議？（沈む魔球フォークボールの空気力学）

SUMMARY Key Words : Baseball aerodynamics, Aerodynamic force, Magnus effect, Ball spin, Forkball, Fastball, Wake Aerodynamic behavior of forkball and fastball are studied in a stand point of fluid dynamic research. The fastball rotates in backspin and aerodynamic lift force acts on it is toward upward by Magnus effects. This lift force is the same magnitude with gravity force for good fastball.

投げてるぼくも、なんであんなクソボールを振るんだろう、と思いますよ。
