| Abstract: | On the basis of fluid mechanics knowledge,this paper studied the characteristics of motion of spinning basketball with various directions theoretically from the angle of dynamics.Furthermore,a thorough analysis and discussion was made on the influence of top spin,back spin or side spin on the shooting average by mechanics method and velocity vector combination.The result showed that spin is a very important factor on shooting.The target was to provide some useful suggestion theoretically for basketball teaching and training. |
