物理图象是指在直角坐标系中绘出的表示两个物理量之间关系的函数图象．用图象来表示物理规律往往比公式法和列表法形象直观，许多抽象的概念用图象表示更加形象化，有助于学生的理解．中学物理中存在着大量的物理图象，因此，图象课的教学也是中学物理教学中的一个重要环节．? A physical image is a functional image that represents the relationship between two physical quantities plotted in a Cartesian coordinate system. The use of images to represent physical laws is often more intuitive than formulas and list methods. Many abstract concepts are more visualized with images and help students understand them. There are a large number of physical images in the middle school physics. Therefore, the teaching of image lessons is also an important link in the physics teaching in middle schools. ?
