摘要
本文以铅球和跳远为例,计算空气作用力对推铅球和跳远成绩的影响,为寻找减小阻力的方法提供依据。同时,本文的计算公式也可用于其它有类似运动轨迹的体育项目。
When moving in the air, men and objects are affected by the aerodynamic force unavoidably. Because there are various factors can affect the aerodynamic force, it is difficult to calculate the aerodynamic force accurately, therefor; it is often neglected while analyzing the motion of men or objects in the air. In fact, if the aerodynamic force is neglected, it is difficult to explain the motion of men or objects in the air satisfactorily either from physical significance or from the calculated result and it is also unfavorable for researching the optimum technique. So sufficient attention should be paid to the aerodynamic force. Through analysis of the motion in the air shot put or long jump, this paper give a formula to analyze the effect of the aerodynamic force to the performance of shot put and long jump, and provide reference for the method to reduce air resistance. Meanwhile, this formula can also be applied to analyze the other sports events with similar motion curve, for example, hammer throwing.
