学习物理,不做题不行,但也万不可在题海中拼命。要想提高解题的能力,须从以下几个途径入手。 一、在概念上多下功夫 物理概念是在解答物理习题中进行判断、推理和论证的基础。在许多情况下,更换概念中的一个字将会导致错误和混乱,正所谓一字之差,天壤之别。怎样才能正确理解物理概急呢?这就要求在每接受一个新概念时,一定要认真地进行思考和领悟。概念中的一词一句都有它的特别意义,尤其是那些关键性的字眼、限定性的
If you study physics, you can’t do the same thing, but you can’t do it in the sea. To improve the ability to solve problems, we must start from the following ways. First, make more efforts on concepts The concept of physics is the basis for making judgments, reasonings, and arguments in answering physical exercises. In many cases, changing one word in the concept will lead to mistakes and confusion. The difference between the two is a world wide difference. How can we correctly understand the urgency of physics? This requires that every time we accept a new concept, we must seriously think and comprehend. The word in the concept has its special meaning, especially the key words and the restrictive ones.
