全日制普通高级中学物理教科书（试验修订本·必修）在《直线运动》内容中充分体现了“同时运用公式和图象两种数学工具描述物理量之间的关系”。这不仅便于学生对比掌握，而且也相对强调了图象的地位和作用，因此要重视图象的教学。一、说明图象的来龙去脉在讲授位移图象和速?
Full-time ordinary high school physics textbooks (experimental revisions and compulsory examinations) fully embodies the “simultaneous use of mathematical and mathematical tools to describe the relationship between physical quantities” in the content of “straight motion”. This is not only convenient for students to grasp, but also relatively emphasizes the status and role of the image, so we must pay attention to the teaching of images. First, explain the ins and outs of the image to teach the displacement image and speed?
