有些物理题,由于思考的角度不同,其解法可能有很多种·而有的题目,如果仅仅按照常规思路,单纯围绕所要求解的物理量兜圈子,问题有时就变得相当复杂,甚至会无从下手·如果换个角度,根据所给题目中各物理量之间的关系,通过对与所求量相联系的其他量的分析,进而间接地对所求量做出判断,解决问题往往就会变得相当简单·间接地求得某些量的方法,可称之为舍近求远法·
Some physics problems, because of their different perspectives, may have many solutions to their problems. If you simply follow the conventional thinking and simply circle around the physical quantity of the solution, the problem sometimes becomes very complicated, and you may even be unable to start. If the angle is changed, according to the relationship between the physical quantities in the given subject, through the analysis of other quantities related to the quantity sought, and then indirectly making judgments on the quantity sought, solving problems will often become quite simple. ·The method of obtaining some quantity indirectly can be referred to as the nearest distance method.
