力学知识难、繁、知识点琐碎,要想把力学知识弄懂弄通,对于刚学物理的学生来说确实困难,因此要使前后知识联系起来加以理解才能起到一定的效果。下面以一道力学综合题为例谈谈怎样化难为易,融会贯通地理解知识和总结解题规律的。 Knowledge of mechanics is difficult, complex, and trivial. If you want to understand mechanical knowledge, it is really difficult for students who just studied physics. Therefore, it is necessary to make sure that before and after the knowledge is linked and understood. The following uses a comprehensive example of mechanics as an example to talk about how to make it difficult to understand, understand the knowledge and sum up the laws of problem solving.
