所谓图象解题法就是根据题意把题目中抽象复杂的内容转化为形象可观的物理图象,把复杂的物理量代数关系转化为简单而简明的几何关系,这样物理过程变得清晰起来,解题思路也会变得通畅,从而达到了化繁为简、化难为易的目的。在物理解题过程中,恰当地运用图象,是提高解题效率的一种有效的方法,同时也是激发学生学习兴趣,提高学生思维能力的有效途径。下面,笔者结合具体实例来进行说明。一、运用v-t图象解题v-t图象能够把繁复的物理过程直观地表现出来,让人一目了然,这样解题过程就会变得简洁起来,从而使求解过程得以优化。例1:一辆小车从静止开始做匀加速直线运动,过了一段时间后又做匀速直线运动直到停止,已知这辆车共运动
The so-called image problem-solving method is based on the title of the subject of the abstract and complex content into a considerable image of the physical image, the complex relationship between physical algebra into a simple and concise geometric relationship, so that the physical process becomes clear, the solution Problem ideas will become smooth, so as to achieve the purpose of simplification, the difficulty is easy. In the process of physical problem solving, the proper use of images is an effective way to improve the efficiency of problem solving, and it is also an effective way to stimulate students’ interest in learning and enhance their thinking ability. Below, the author with a specific example to illustrate. First, the use of v-t image to solve v-t images can complex physical process intuitively demonstrated, people at a glance, so that the problem-solving process will become concise, so that the solution process can be optimized. Example 1: A car from the rest began to do uniform acceleration linear motion, after a period of time and do a uniform linear motion until stopped, it is known that the car was moving
