图象问题是物理学中的常见问题,在很多章节都有出现.几乎贯穿于整个中学物理课程的始末.图象题在我们平时的练习和考试中经常出现,也是中考试卷中的一种必考题型.我们的课本在描述物理规律时,常用以下几种方式:1.语言描述;2.物理公式;3.物理图象.以匀速直线运动为例,用语言描述就是:物体沿着直线且速度不变的运动,叫作匀速直线运动.用公式描述就是“v=s/t”.用图象描述,如图1所示.如果说物理 The image problem is a common problem in physics and appears in many chapters, which runs through almost the entire middle school physics curriculum.Image problems are often found in our usual practice and exams and are also a must Test questions. Our textbooks describe the laws of physics, the following ways: 1. Language Description; 2. Physical equations; 3. Physical image. And the same speed of movement, known as uniform linear motion.Described by the formula is “v = s / t ” Image description, as shown in Figure 1. If the physical
