THE OPTIMUM RELEASE ANGLE IN SHOT PUT

摘要: 利用运动叠加原理通过对铅球运动的恰当分解, 提出了一种计算最佳出手角的新方法, 并与传统方法就两种不同情形进行了对比, 说明了新方法的物理思想.

Abstract: By using the superposition principle of motions todecompose the projectile motion of the shot into a combination of tworectilinear motions, this paper proposes a new simple method to analyzethe optimum release angle in shot put. The results are compared withthose obtained by the traditional methods under two different conditions.
