高中物理有一类带电粒子在复合场中运动问题,已知条件特别少,有的甚至几乎是纯文字题,给出或要求画出三维坐标系,从而考查学生的空间想象能力,重力场、电场和磁场知识规律的综合分析能力以及利用物理图景解决实际问题的能力,体现了物理与科学、技术、社会的结合和联系,符合新课程标准.现就这类试题归类解析:一、带电粒子在三维复合场中的直线运动直线运动是学生接触的最为简单的运动方式,但是由于处在了三维复合场中,需要加
High school physics There is a class of charged particles movement in the complex field, known conditions are particularly small, and some even almost purely text questions, given or asked to draw a three-dimensional coordinate system to examine the students’ spatial imagination, gravitational field, electric field And magnetic field knowledge of the law and the ability to analyze the use of physics to solve practical problems, reflects the combination of physics and science, technology, society and contact, in line with the new curriculum standards are now categorized into such questions: First, the charged particles Linear motion in a three-dimensional composite field Linear motion is the easiest way to get in touch with a student, but due to being in a three-dimensional compound field,
