高中物理力学中,弹簧是一个典型的代表,与弹簧有关的问题也是不胜枚举。研究力时首先要明确力的三要素:大小、方向、作用点,研究弹簧类问题时,首先应明确弹簧原长位置、形变位置和平衡位置这三个位置,找出弹力大小与形变量的劲度系数k,在计算做功时,根据关系系数可以求出平均作用力,进而计算出做功大小,本文以例题形式对典型弹簧求解进行讲述。
In high school physics mechanics, the spring is a typical representative, and spring-related issues are numerous. When studying the force, we must first make clear the three elements of force: the size, the direction and the point of action. When studying the spring-like problem, we should first determine the position of the original spring, the position of the deformation and the position of the equilibrium. Stiffness coefficient k, in the calculation of work, according to the relationship between the coefficient can be calculated by the average force, and then calculate the size of the work, this paper in the form of a typical example of the spring to describe the solution.
