摘要
从动力学的角度出发,结合流体力学知识,分析了几种不同旋转形式的篮球运动规律,在此基础上利用力学方法和速度的矢量合成法,探讨前旋球、后旋球及侧旋球对投篮命中率的影响。指出球的旋转这一因素在投篮过程中的重要性,为篮球教学与训练提供理论指导。
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.
