在观看东京奥运会乒乓球比赛的过程中，我们发现运动员们打出的乒乓球的运动轨迹多为弯曲度极大的弧线，部分甚至在水平方向有所偏转。出于好奇，我们观察了许多视频资料，并通过亲自实验观察和对乒乓球进行受力分析，总结出了乒乓球运动的弧线与触球点和挥拍方向之间的关系，并了解了马格努斯效应和其在其他领域的运用。  

While watching the table tennis competition at the The 2020 Tokyo Olympic Games, we noticed that the athletes hit the table tennis balls with curved arcs, some of which were even deflected in the horizontal direction. Out of curiosity, we observed many video materials, and through personal experimental observation and force analysis of table tennis balls, we concluded the relationship between the arc of table tennis motion and the point of contact and swing direction, and learned about the Magnus effect and its application in other fields.
