带电粒子在复合场中的运动在高考考查中一直处于重点考查的内容。从受力角度看:复合场中粒子可能受到重力、电场力、洛伦兹力。如果有轨道约束粒子的运动,那么粒子还可能受到弹力、摩擦力等力。从运动形式的角度看:带电粒子在复合场中可能做直线运动、匀速圆周运动、类平抛运动、非匀变速曲线运动等,正是由于研究对象受力个数
The movement of charged particles in the composite field has always been the focus of examination in the college entrance examination test. From the force point of view: the composite field particles may be subject to gravity, electric field force, Lorentz force. If there is orbital movement of particles, then the particles may also be elastic, friction and other forces. From the perspective of the form of motion, charged particles can make linear motion, uniform circular motion, flat throw motion and non-uniform velocity curve motion in the composite field. It is because of the number of objects
