物理图象是一种特殊且形象的数学语言和工具,它能够形象、简洁地展现两个物理量之间的关系,清晰、直观地表达物理过程,正确地反映物理规律.动量守恒中涉及的图象问题有以下3类.一、识图根据题中所给物体的物理情景,识别其运动过程中物理量随时间或位移的变化规律图象;求解的关键是看清图象中的“点”、“线”、“斜率”、“截距”、“面积”的物理意义.
Physical image is a special and figurative mathematical language and tool that can vividly display the relationship between two physical quantities, express the physical process clearly and intuitively, and correctly reflect the physical laws. The diagrams involved in conservation of momentum As the problem has the following three categories: I. Recognition According to the subject given to the physical scene, identify the movement of physical quantities with the time or displacement of the law of change; the key to solving is to see the image of the “point ”, “ Line ”, “ slope ”, “ intercept ”, “ area ”.
