带电粒子在场中的运动问题是高中物理的教学重点内容,也是历年高考的必考内容,且题型灵活多变,重点考查同学们分析问题和解决问题的能力,以及处理较为复杂问题的方法,能够突出高考的命题要求.带电粒子在场中的运动问题,本质上是物体的动力学问题和功能问题.为了帮助同学们更好的掌握这一核心考点,相关策略分析如下.一、带电粒子在场中运动的基本情况分析1.带电粒子在场中的运动,实际上仍是一个力学问题,分析

The movement problem of charged particles in the field is the key content of high school physics teaching and also the compulsory content of college entrance examination over the years. Moreover, the type of questions is flexible and changeable. The focus is on examining the students’ abilities to analyze and solve problems and to deal with more complicated problems. Can highlight the college entrance examination proposition requirements.The movement of charged particles in the field, is essentially the object of kinetic problems and functional problems.In order to help students better grasp of this core test sites, the relevant strategies are as follows.A charged particles present Analysis of the basic situation in motion 1. The movement of charged particles in the field is actually still a mechanical problem,
