我们进行了实验，其中一个足球从机器发射，而两个高速摄像机记录的轨迹的一部分。使用轨迹数据和公布的阻力系数，我们提取升力系数的足球。我们确定了大范围尾旋参数的升力系数，其中包括几个目前风洞还没有得到的尾旋参数。我们的轨迹分析技术不仅是专业体育科学家的宝贵工具，它也适用于具有本科经典力学背景的学生。
We performed experiments in which a soccer ball was launched from a machine while two high-speed cameras recorded portions of the trajectory. Using the trajectory data and published drag coefficients, we extracted lift coefficients for a soccer ball. We determined lift coefficients for a wide range of spin parameters, including several spin parameters that have not been obtained by today's wind tunnels. Our trajectory analysis technique is not only a valuable tool for professional sports scientists, it is also accessible to students with a background in undergraduate-level classical mechanics.
