图象题是中考物理试卷中常见的一种题型,考生要快速准确地解答图象题,必须要做到“四会”.一、会读图读图是解图象题的前提,在读图过程中,首先要理解两个坐标轴的含义,进而读出图象所代表的物理意义.例1图1中,反映物理量之间的关系正确的是()解析解答此类试题时,首先要知道图象描述的是什么问题,什么曲线代表什么关系.其次要知道垂直于x轴的直线和平行于x轴的直线于图象的交点代表什么物理量相同,这是解决
Image test is a common type in senior high school entrance examination papers, the candidates to quickly and accurately answer the image, you must do Four reading will be the premise , In reading the process, we must first understand the meaning of the two axes, and then read the image represents the physical meaning.Example 1 Figure 1, reflecting the relationship between physical quantities is correct () analytical solution to such questions , We must first know what the image description is, what the curve represents the relationship.Second, we must know that the intersection of the line perpendicular to the x-axis and the line parallel to the x-axis represents the same physical quantity, which is the solution
