In football of recent years, the shape of the panel of the ball has changed greatly with each year, and the types of balls used by the professional leagues and international conventions of each country are not unified. Changes in panel shape greatly influence aerodynamic characteristics, and characteristics, characteristics, and performances change as balls are different, so the game affects the game in a professional world where delicate play is required. In our experiment, we measured the impact point of a soccer ball using an injection machine. Capture the influence of different panel shape on the trajectory of a soccer ball. As a result, it was found that if the number of panels is small, it tends to be aimed at, and even if the number of panels is the same, the landing characteristics are different.
