运动着的羽毛球,如果其筒口向着运动前方,那么,它就会翻“跟头”.如羽毛球受到拍击,向前飞离球拍的那一瞬间,羽毛筒口是向前的,接着它就会翻个“跟头”.又如筒口向下自由落下的羽毛球,在它降落的初期,简口是向着运动方向的,接着也会翻个“跟头”.这是为什么呢?这是由于羽毛筒里受到前方气流冲击的缘故.气流冲击为什么能使它翻“跟头”呢?让我们从一个实验说起吧. A sporty badminton, if its mouth is facing in front of the sport, then it will turn over. If the shuttlecock is beaten and flies forward from the racket, the plume is forward, and then it will turn over. Another example is the badminton where the mouth of the shuttlecock falls down freely. In the early stages of its landing, the Jane’s direction is toward the direction of movement, and then it will also turn over the “toggle.” Why is that? This is due to the forward flow of air in the feather cylinder. The reason for the shock. Why can air flow make it turn over? Let’s start with an experiment.
