综观近几年的中考物理命题,通过正确分析函数图象解决物理实际问题类考题呈逐年上升趋势,并且知识覆盖面越来越广,新颖题型层出不穷,应引起广大师生的注意。现举几例说明,供大家参考。例1 如图1所示为汽车沿直线运动时的路程一时间图象。图中s轴表示汽车离开出发点的路程。请根据此图分析汽车的运动情况,并画出描述汽车在这段时间内运动的速度-时
Looking at the physics propositions of the middle school entrance exams in recent years, through the correct analysis of functional images to solve the physical problems, the examination questions are on the rise year by year, and the coverage of knowledge is getting wider and wider. Novel questions are emerging in an endless stream, which should arouse the attention of teachers and students. Here are a few examples for your reference. Example 1 As shown in Fig. 1 is a time-lapse image of a car traveling along a straight line. The s-axis in the figure shows the distance the car leaves the starting point. Please analyze the movement of the car based on this graph and draw the speed of the car during this period of time.
