在乒乓球运动中,由于旋转的球上下方空气流速不一样,根据伯努利方程,流速大的一方压强小而流速小的一方压强大,这就导致了乒乓球在行进过程中出现了弯曲轨道,即弧线球。乒乓球不同类型的旋转产生的弧线不一样,也使球前进的速度不一样,选手可通过球的运行速度来判断球的旋转方式。
In table tennis, due to the different air velocities above and below the spinning ball, according to the Bernoulli equation, the one with the smaller pressure and the smaller pressure have a greater pressure, which leads to the bending of the table tennis ball Track, that arc ball. Table tennis different types of rotation produces different arcs, but also make the ball forward speed is not the same, the player can determine the ball’s rotation speed by the ball’s running speed.
