物理图像往往能以直观、简单形式来描述物理过程,所以分析动态的物理过程有其独特的魅力.物理的动态变化过程,从物理量与物理量的关系来看往往表现为某种函数关系,也正因为函数描述事物逻辑变化具有不可替代的功能,所以其作为描述主体之一的物理过程,函数图像是一种重要的研究物理问题的工具.这也是物理高考命题考查的重要内容,它反映考生对物理过程的理解的数学逻辑 Physical images often describe the physical processes in an intuitive and simple way, so the analysis of dynamic physical processes has its unique charm. The dynamic process of physical changes usually shows some kind of functional relationship from the relationship between physical quantities and physical quantities, Because the function describes the logical change of things has an irreplaceable function, as a description of the main body of the physical process, the function of the image is an important tool to study the physical problems .This is also an important part of the physical college entrance examination test, which reflects the candidates Mathematical logic for the understanding of physical processes
