物理习题中有些问题看上去无法解决,解题时不知从何处下手.遇到这种题型首先不要急于求解,应仔细审题,在仔细分析物理情境的基础上,将该题与已经做过的题型相类比,找出它们的共同特点,“巧”借已学过的物理情境去推敲、分析问题,找出解题的突破口.下面利用例题浅析如何“巧’借物理情境求解问题. Some problems in physics exercises can’t seem to be solved. When you solve a problem, you don’t know where to start. When you encounter this type of problem, don’t rush to solve it first. You should examine the problem carefully. Based on a careful analysis of the physical situation, the problem has already been solved. The questions are analogous to each other, to find out their common characteristics, “skillfully” to use the physical situation has been learned to scrutinize, analyze problems, find a breakthrough point for solving problems. The following example using an example of how to “smartly” solve the problem by physical situation .
