Sometimes, however, the results are wrong. If you are familiar with some of the test results are correct way, it seems 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 results of physical problems can play a guiding role. First, the physical test method Physical problems are generally in line with certain physical meaning of the answer. If you count
