众所周知,所有自然现象的变化过程都受能量守恒和转化定律的制约。除能量守恒等少数定律外,每一个物理学定律都有它的适用范围。因为无论何种定律,都是在有限的范围里,根据有限的事实,在观察和实验的基础上用理想化的方法经过分析推理总结出来的,因而都带有一定的片面性、局限性。如果我们把从有限范围中得出的结论无限制地推广,就会得出与事实相违背的结果。作为物理教师,不仅要向学生传授物理定
As we all know, the process of all natural phenomena is constrained by the law of conservation of energy and conversion. In addition to the few laws of energy conservation, every physics law has its scope of application. Because no matter what the law is, in a limited range, based on limited facts, based on observation and experimentation, it is analyzed and inferred using idealized methods. Therefore, it all has certain one-sidedness and limitations. If we extend the conclusions drawn from a limited range without limit, we will come to a conclusion that is inconsistent with the facts. As a physics teacher, we must not only teach students physical orientation
