有许多学生在学习物理、解决物理问题时只注重如何套用公式以及数学演算,缺少运用准确的图形来构建物理模型、分析物理情景的意识,或者不会画图来分析,或者不知道从哪开始画图,画些什么样的图形来分析物理问题,自然就学不好物理了。还有学生存在这样的现象:上课听老师讲都会,自己独立解答却很困难。原因在哪呢?其实还是在作图上,即通过作图,构建准确的物理模型,再现题意的物理情景。 Many students pay attention to how to apply formulas and mathematical calculus while studying physics and solving physical problems. They lack the use of accurate figures to construct physical models, analyze the consciousness of physical situations, or do not draw or analyze, or do not know where to start drawing , What kind of graphics to draw the analysis of physical problems, nature can not learn physics. There are students such a phenomenon: listening to the teacher to listen to class, their own independent answer is very difficult. The reason why? In fact, or in the mapping, that is, through mapping, build accurate physical model, reproduce the original physical scenario.
