带电粒子只在电场力作用下直线运动是我在广东省珠海市牛顿奖现场赛中的一节开放式的教学实践,在这里与同行分享。本节课是系统复习了电场的力的性质和能的性质,且学生已经理解并初步掌握了两个内容之后,进一步理解力与运动,功与能的关系,运用力学知识来处理电学问题,从而提高学生分析问题的能力,综合能力,运用数学方法解决物理问题的能力。以例题的形式设计带电粒子只在电场力作用下直线运动以及带电粒子在电场力、重力作用下直线运动两个探究
Charged particles only under the linear motion of electric field force is an open-ended teaching practice in the on-site contest of Zhuhai Newton Festival in Zhuhai, Guangdong Province, where I share with my colleagues. This lesson is a systematic review of the nature and nature of the force of the electric field. After the students have understood and mastered the two elements initially, they further understand the relationship between force and movement, work and energy, use mechanical knowledge to deal with electrical problems, Thereby enhancing students ability to analyze problems, comprehensive ability, the ability to use mathematical methods to solve physical problems. In the form of the example of the design of charged particles only under the action of electric field linear motion and charged particles in electric field force, the linear motion of gravity under two
