For this study, five soccer balls were used, each having 32 panels with different surface textures. Their aerodynamics were examined via wind-tunnel experiments and then several non-spin trajectories were calculated for each ball. The results showed that the aerodynamic forces acting on a soccer ball change significantly depending on the surface texture of the ball, which in turn influences flight trajectories. The study contributes to an understanding of how a soccer ball¡¯s surface influences the aerodynamics, which may impact the future design and development of soccer balls %K Aerodynamics %K football %K soccer %K surface texture %K trajectory %U https://journals.sagepub.com/doi/full/10.1177/1754337118794561
