牛顿运动定律中弹簧类问题是高中物理中常见的一类题,也是学生比较头疼的问题,常常无从下手,其实只要认真分析这类题目的特点,就不难发现,只要抓住“两个状态,一个过程”,分析与弹簧相连的物体的受力和运动,问题就会迎刃而解.以下面3题为例加以说明.图1例1.一弹簧秤秤盘的质量M Newton’s law of movement in the spring class is a common high school physics class problems, but also students a headache, often impossible to start, in fact, as long as carefully analyze the characteristics of such topics, it is not difficult to find, as long as the grasp of “two states , A process ”to analyze the force and movement of the object connected to the spring, the problem will be solved.An example to be described below as an example 3.
