高中物理受力分析是物理学习中最重要的教学内容,它贯穿整个高中阶段,而有的学生因为突破不了,导致物理成绩低,对学习失去兴趣。一、形成原因(一)力是物体间的相互作用。在受力分析过程时,一定抓住力的三要素大小、方向、作用点。这种相互作用只能凭着各力的实际条件和方向要求,再加上抽象的思维想象去画,不想实物那么明显,而刚踏入的高中生来说,习惯于直观形象,缺乏抽象的逻辑思惟,所以形成了难点。

Physics analysis of high school physics is the most important teaching content, which runs through the entire high school stage, and because some students can not break through, resulting in low physical performance, lost interest in learning. First, the formation of reasons (a) force is the interaction between objects. In the stress analysis process, we must grasp the power of the three elements of size, direction, point of action. This interaction can only rely on the actual conditions of force and direction requirements, coupled with the abstract thinking of imagination to paint, do not want the physical so obvious, and just entering the high school students, accustomed to visual images, the lack of abstract logic Thinking, so formed a difficult point.
