物理图像选择题的解题关键是挖掘图像的内涵，运用物理知识分析推理．解题时首先要根据题给图像对其描述的物理过程或相关物理量的变化规律作定性分析，弄清坐标轴所代表的物理量，明确研究的是哪两个物理量的制约关系．其次要根据图像中的图线特征，初步掌握图线反映的物理过?
The key to solve the problem of physical image multiple-choice questions is to mine the connotation of the image and use physical knowledge to analyze reasoning. When solving a problem, first of all, according to the qualitative analysis of the physical process of the description of the image to the image or the variation of the relevant physical quantity, the physical quantity represented by the coordinate axis is clarified, and the relationship between the two physical quantities is clearly defined. Secondly, according to the characteristics of the graph in the image, we should initially grasp the physics reflected by the graph.
