带电粒子在电场、磁场和重力场的组合场中或复合场中的运动问题是高中物理的重点内容,也是同学们学习的难点,同时也是高考考查的重点和热点之一。这类问题巧妙地把电场、磁场和重力场的概念与牛顿定律、动能定理等力学、电学有关知识有机地联系在一起,并应用数学工具解决物理问题。这类考题覆盖知识面广,综合性强,对同学们的空间
The movement of charged particles in the combined field of electric field, magnetic field and gravitational field or in complex field is the key content of high school physics. It is also a difficult point for students to study and one of the focuses and hot spots for college entrance examination. Such problems skillfully link the concepts of electric field, magnetic field and gravitational field with mechanical and electrical knowledge such as Newton’s law and kinetic energy theorem, and apply mathematical tools to solve physical problems. Such questions cover a wide range of knowledge, comprehensive, on the space for students
