带电体在电场中的圆周运动是近几年高考和高校自主招生考试的的热点问题.为应对新的自主招生考试模式,笔者根据几例自主招生考题和它的母题谈带电体在电场中圆周运动这一重要的模型.并将这一模型用于开放式探究性复习课的课堂,这将有助于培养学生的联想能力、知识与方法的迁移能力、空间想象能力、总结归纳能力,更为突出的是培养学生在物理学习中作图这一技术素养.1.带电体在点电荷电场中的匀速圆周运动
The circular motion of the electrified body in the electric field is a hot issue in the college entrance examination and college entrance examination in recent years. In response to the new independent enrollment examination model, the author discusses the electrification of the electrified body in the electric field based on several independent enrollment questions and its motif. This important model of circular motion, and the use of this model in an open inquiry review class, will help develop students’ ability to associate, transfer knowledge and methods, spatial imagination, and sum up What stands out more is the cultivation of students’ literacy in physics learning. 1. The uniform circular motion of a charged body in a point charge electric field.
