能量问题在高中物理当中占有很大比重,而且一向是高考的重点考查内容.尤其是在客观题中往往考查的非常灵活,但是只要在平时的学习中留心抓住能的一些特点,一定能找到迅速解决问题的妙法.下面我针对能的标量性 Energy problems account for a large proportion of high school physics, and has always been the focus of examination of the college entrance examination content, especially in the objective questions are often very flexible test, but as long as the usual learning to seize some of the features can be found Quick way to solve the problem. Below I can target the scalar
