非线性变化类问题一直是历届高考中的热点、难点,体现了对学生能力命题的立意。本文就针对高中物理常见非线性变化类问题进行梳理,归纳出一般解题思路,引发学生深入思考、提升学生思维能力。1.利用图象法处理v-t非线性关系对于非匀变速运动而言,无法用匀变速运动的规律去处
The problem of non-linear change has always been a hot and difficult issue in the previous college entrance examination, reflecting the intention of the proposition of student ability. This article sorts out the common nonlinear changes in high school physics, sums up the general problem-solving ideas, and triggers students to think deeply and improve their thinking ability. 1. Using image method to deal with v-t nonlinear relationship For non-uniform speed-changing motion, it is impossible to use the law of uniform variable speed motion
