物理图象是一种形象直观的“语言”,它具有形象地表达物理规律,直观地叙述物理过程,明显地表示物理量之间的依赖关系的优点·利用物理图象解题不仅思路靖晰,而且在很多情况下可使解题过程得到简化,具有比其它方法更巧妙、更灵活的的独特效果·下面就中学阶段中最常见的v—t图象 The physical image is a visually intuitive “language”. It has the physics law that expresses the image, intuitively narrates the physical process, and clearly shows the advantages of the dependencies between physical quantities.
