做功是能量由一种形式转化为另一种的形式的过程。做功的两个必要因素:作用在物体上的力和物体在力的方向上通过的距离。经典力学的定义:当一个力作用在物体上,并使物体在力的方向上通过了一段距离,力学中就说这个力对物体做了功。

而第二种体例则是将能量转达给全数腿部,推动腿部和足部成一团体跺击大地,地面临腿部做功(Acting)发生的能量(Energy)无法转变为塑性势能被腿部招揽,宁愿面貌丑陋,不愿思想丑陋。间接传达给表皮和大脑(Brain),不利于身段康健。

Compared with the swing lift racket serve, the back bending depth of non-swing lift racket serve is shallow, and has short distance to work on the racket acceleration. But it is more of explosive power.
与有下摆引拍发球相比,无下摆引拍发球的“搔背”深度小,对球拍做功的加速距离短,但无下摆引拍的发力更具有爆发性,对拍头加速的最终效果并不比有下摆引拍发球差。
