求解高中物理习题常常很费时费力,然而求出的结果却有时是错误的,这确实令人感到懊恼和心烦。因而若能熟悉并掌握一些检验结果是否正确的方法,就显得再好不过了。检验结果是否正确一般可从以下两个方面进行考虑:一是检验所列的方程是否正确;二是检验计算结果及单位的书写是否正确。下面举例说明,希望能对同学们正确地检验物理解题结果是否正确,能够起到一定的指导作用。
Solving high school physics exercises is often time-consuming and painstaking, but the results are sometimes wrong, which is indeed annoying and upset. So if you are familiar with and test some of the test results are correct, it would be better. The test results are correct Generally can be considered from the following two aspects: First, test the correctness of the listed equations; the second is to test the calculation results and the unit is written correctly. The following examples illustrate the hope that students can correctly test the physical problem-solving results are correct, can play a guiding role.
