带电粒子在匀强电场中由于受力和初速度不同,所以运动情况就不同,带电粒子在匀强电场中可以做直线运动,也可以做曲线运动,还可以做往返运动等。带电粒子在匀强电场中运动问题是高中物理的重要知识点,也是同学们学习的难点,同时也是高考的一个热点。解决这类问题的方法是:首先对带电粒子的运动状态特点和受力情况进行分析,然后根据带电粒子的运动情形,恰当选用力学观点或能量观点列方程求解。下面举例分析,请同学们参考。
Charged particles in a uniform electric field due to force and the initial velocity is different, so the movement is different, charged particles in the uniform electric field can do a straight line, you can also do the curve movement, you can also do back and forth movement. Charged particles in uniform electric field movement problem is an important high school physics knowledge, but also difficult for students to learn, but also a hot college entrance examination. The way to solve this kind of problem is as follows: First, we analyze the characteristics of moving state and the force of charged particles, and then use the mechanics viewpoint or the energy viewpoint equation to solve them according to the movement of charged particles. The following example analysis, please students reference.
