函数图象能把抽象复杂的物理过程简洁明了地表达出来,是解决物理问题的有效手段。通过对物理问题进行定性分析或解析计算,可利用函数图象把物理量之间的关系转化为直观的一定形状的几何图形。当所研究的物理过程较复杂时,函数图象往往是多段的、非线性的。针对高中物理不同类型的问题,探讨如何作出相应的非线性函数图象。
Function images can express the abstract and complex physical processes concisely and clearly, which is an effective way to solve the physical problems. Through the qualitative analysis of physical problems or analytic calculation, the function image can be used to transform the relationship between the physical quantities into an intuitive geometric shape of a certain shape. When the physical processes studied are complex, the function images tend to be multi-segment, non-linear. For different types of high school physics problems, to explore how to make the corresponding nonlinear function image.
