门球运动中有两大核心技术,一是击球命中率,二是击送球到位率,即力度。前者比较具体,易于操作,后者则比较抽象,难以驾驭,本文试就击球力度这一问题做一肤浅的探索,不妥之处,请球友们赐教。首先明确一下门球中的力,即什么在门球运动中挥杆击球,从而使球产生运动。所谓力度即是力的大小,问题的关键是这个度如何掌握,这是我们重点探讨的问题。如果我们视球为一个质点,那么这个力的大小从理论上说,应当符合牛顿第二定律,即 F=ma。这里 F 表示力,m 表示球的质量,a 表示加速度。由于门球球的大小、形状、重量都是一样的,也就是说质量 m 在这里是一个常量,由此可知力 F 与加速度 a 是
There are two core techniques in the croquet movement, one hit the hit rate, and second hit the ball in place rate, that is, intensity. The former is more specific and easy to operate, while the latter is more abstract and difficult to control. This article tries to make a shallow exploration on the batting issue. First clear the force in the goalkeeper, that is, in the goalkeeper swing hit the ball, so that the ball movement. The so-called strength is the size of the force, the key issue is how to master this degree, which is our focus on the issue. If we regard the ball as a particle, then the size of this force should theoretically be in accordance with Newton’s second law, F = ma. Where F is the force, m is the mass of the ball, and a is the acceleration. As the size, shape and weight of the croquet ball are the same, that is to say, the mass m is a constant here, so that the force F and the acceleration a are
