动能定理无论是在机械能题目中还是在带电粒子在电场中的运动中解题都能够成为一个简单的方法,高考压轴题中,涉及它的题目所占比例极高。尽管动能定理内容简单,却仍有很多学生在使用过程中往往出现这样或那样的问题,为了高效 The kinetic energy theorem can be a simple method both in the mechanical energy problem and in the movement of the charged particle in the electric field. In the college entrance examination, there are a great deal of problems involved in it. Although the kinetic energy theorem is simple, there are still many students who often have this or that problem during their use. In order to be efficient
