摘要
本文从物理学的角度出发,分析了运动员在实际推铅球的过程中影响铅球飞行距离的各种要素.结合实际情况通过物理公式来计算铅球飞行距离并进行综合分析.实验证实影响铅球飞行距离的3个要素是出手角度、出手速度和出手高度,并分析了这3个要素之间的关系和各个单变量对铅球飞行距离的影响状况.分析结果显示,3个因素中出手速度对飞行距离的影响最大,其次是出手角度,出手高度影响程度最小;且最佳出手角度不是一个特定的数值而是一个大体范围.
From the perspective of physics,various factors,which affect the flying distance of shot put in the actual process,were analyzed.Combining actual conditions,the flying distance of shot put was calculated by physical formula and analyzed comprehensively.Experiments confirmed that the factors which affect the flying distance of shot put are the pushing angle,pushing speed and pushing altitude.The relationship between the three elements,and the influence of a single variable on the flying distance were also analyzed.Our results show that the pushing speed is the biggest effect to the flying distance,and the second is the pushing angle.The influence degree of pushing height to flying distance is the smallest.Furthermore,the best pushing angle is not a specific value but a general range.
