The description of the sports state of soccer in sports is complicated. We analyze the force on the soccer's motion process from two angles of plane and curved surface respectively, and describe its motion track, especially the causes of soccer's arc motion, so as to explain the motion state of balls such as soccer. Football curve ball is also called “banana ball”. In football matches, it can make it difficult for the defending side to make a correct judgment. Therefore, it has a fascinating overall effect in the competition and is a very popular technology in contemporary football technology. On the basis of literature review, the factors such as ejection angle, rotation and air resistance of arc ball are analyzed, and the stress process of football in flight is decomposed.A scientific model was established without considering other secondary factors, and the “hot zone” that can shoot the arc ball was analyzed, and the best shot area of the arc ball was given. At the same time, the football trajectory is simulated. The flight path of the curved ball is reproduced by input parameters to objectively determine whether the soccer ball hits the goal.
