图像题是每年各地中考必考的题型,因为它把数学知识与物理知识密切地结合起来,能够充分考查学生的整体素质.因此备受命题者的青睐.下面从近年各地中考题中选析几例,希望大家能够从中受到启迪.例1 P、Q是同一直线上相距12 m的两点,甲从P点、乙从Q点同时沿直线相向而行,它们运动的s-t图像如图1所示.分 Image title is the exam each year throughout the exam will be the type of questions, because it combines mathematical knowledge and physical knowledge, can fully examine the overall quality of students, so much the proponent of all ages. Example, I hope you can be inspired from Example 1 P, Q is the same line 12 m away from two points, A from P, B from Q point at the same time along a straight line to the line, their movement st image shown in Figure 1 Show.
