反推法是解答物理题重要的方法之一,本质上是一种解题的思路.它不是从题目已知的条件出发,推导出问题的答案;而是从问题本身着手,根据各物理量之间的逻辑关系,找出解决问题必要的条件,从而得到答案.如果这些因素和条件未知,就根据物理量之间的关系,找出求解这些数值的要素与条件……,如此层层倒推,直到找到所有想知道的条件和数据,是一种用逆向思维解题的方法.物理学是一门重视观察与实验、注重思考、强调知识的理解和应用的学科,除了观察实验、善于思
Back-thrust method is one of the important ways to solve the physics problem, which is essentially a way of solving the problem.It does not derive the answer to the problem from the known conditions of the problem, but starts from the problem itself and according to the physical quantities Find out the necessary conditions to solve the problem, in order to get the answer.If these factors and conditions are unknown, according to the relationship between the physical quantities, find out the elements and conditions for solving these values ......, so layers back down, Until you find all the conditions and data you want to know, it is a way of solving problems with reverse thinking.Physics is a subject that emphasizes observation and experiment, focuses on thinking, and emphasizes the understanding and application of knowledge. In addition to observing the experiment,
