| Abstract: | The flying process of the corners in the soccor forms two resistance forces which have pressing difference, under the effect of the join forces, the balls have to change their regular track and thus the "banana-like" orbit is formed. |

| Keywords: | spinning ball frictional force angular momentum moment of inertia |
