所谓等效思维法,是指在保持效果不变的前提下,对物理问题中的某些因素加以变换、替代、重建,使之更简单、更符合各种理想化模型,从而快捷解决问题的一种思维方法。在近几年物理中考中,有一些旨在考查学生思维灵活性、创造性的力学试题,若利用等效思维法求解,则可化难为易、化繁为简。下面举例说明。 The so-called equivalent thinking method refers to the transformation, substitution, and reconstruction of certain factors in the physical problem under the premise of keeping the effect unchanged, making it more simple and more in line with various idealized models, so as to solve problems quickly. A way of thinking. In the physics exams in recent years, there are some mechanics questions that aim to examine students’ thinking flexibility and creativity. If they are solved using the equivalent thinking method, they can be easily solved and simplified. The following is an example.
