解决初中物理题常用的方法是:分析法、综合法、图解法和推理法等.下面再介绍几种特殊的解法.一、整体法这种方法是把看上去彼此独立的几个物体或不同的几个过程作为一个整体来对待和处理的方法。例1,如图示物体甲与物体乙用细绳连接后挂在天花板上,甲的重量为20kg,绳子质量不计,若悬挂甲和乙两物体的钢丝受到的拉力 The commonly used methods to solve junior high school physics problems are: analysis, synthesis, diagramming, and reasoning. The following describes several special solutions. First, the holistic approach is to look at several objects that are independent or different from each other. The process of treating and treating several processes as a whole. Example 1, as shown in the figure, object A and object B are connected by a string and hung on the ceiling. The weight of A is 20 kg. The quality of the rope is not counted. If the wire of the two objects A and B is pulled, the tension is applied.
