求解综合题,是同学学习上的难点,其原因是综合题所涉及的物理概念和规律较多,不能用单一的规律求解.所以,在遇到综合题时,往往束手无策.本文介绍几种求解方法供同学们参考.1.分析法分析法是从待求量出发,充分利用题设条件和已知量,找出与待求量相关的公式,然后看公式中的其它量是否已知,如有未知,再寻找与此未知量有关的公式……;这样
Solving comprehensive questions is a difficult task for classmates to learn. The reason is that the comprehensive questions involve more physical concepts and laws and cannot be solved by a single law. Therefore, in the event of a comprehensive question, they are often at a loss. This paper introduces several solutions. Method for students to refer to. 1. Analytical method Analytical method is to proceed from the amount to be worked out, make full use of the conditions and the known amount of questions, find out the formula related to the quantity to be sought, and then see if the other quantities in the formula are known, If unknown, look for formulas related to this unknown quantity...
