高中物理中有许多复杂的物理过程,涉及到的物理量数目众多,其遵循的规律对学生来也是晦涩难懂,特别是有些物理量之间的关系限于中学数学工具的原因很难直接用表达式来进行定量的描述,也就很难确定它们之间的大小关系.这时物理图象的引入就会大显身手.图象法的优点是描述物理过程形象直观、物理内涵深刻丰富,图象是联系众多物理量之间的纽 There are many complicated physical processes in high school physics, involving a large number of physical quantities. The laws followed are also obscure to students. In particular, the relationship between some physical quantities is limited to the reason of high school mathematics tools. It is difficult to directly use expressions Quantitative description, it is difficult to determine the size of the relationship between them when the introduction of physical images will show their talents. The advantages of the image method is to describe the physical process of visual image, the rich deep connotation of the image is linked to many New Zealand between physical quantities
