摘要
高中阶段通常会用运动合成或分解的方法来处理匀变速直线运动、平抛运动、类平抛运动及一般的匀变速曲线运动,但能否用运动合成或分解的方法处理高中阶段另一种重要的运动——圆周运动呢?本文以带电粒子在匀强磁场中的匀速圆周运动为例进行分析与验证,得出相关结论,并用这种方法分析两个具体的问题。
In senior middle school physics course,the method of composition and resolution of motions is usually used to deal with uniform variable rectilinear motion,horizontal projectile motion,quasi flat throwing motion and general uniform variable curvilinear motion.Could this method be applied to deal with circular motion that is another important motion in senior middle school physics course?In this paper,the uniform circular motion of charged particles in a uniform magnetic field is analyzed and verified,and relevant conclusions are obtained.Besides,two specific cases are analyzed by this method.
