高中物理习题的解答有时很费力气,但结果有时却是错误的,这着实让人懊恼。如果能够熟悉并掌握一些高中物理习题答案的检验方法,这不仅是解题者的需要,而且也是对物理概念、物理规律的再认识。高中物理习题答案正误的检验一般应从两个方面考虑:一是检验所列方程的正确与否;二是检验计算结果和单位的书写正确与否。下面介绍几种常用的检验方法:
The answers to high school physics problems are sometimes very laborious, but the results are sometimes wrong. This is really annoying. If you can familiarize yourself with and master some of the test methods for answering high school physics exercises, this is not only the need of the problem solver, but also a re-understanding of physical concepts and physical laws. The examination of the correctness of answers to high school physics exercises should generally be considered from two aspects: one is to check the correctness of the listed equations; the other is to verify the calculation results and the correctness of the writing of the units. Here are some commonly used test methods:
