在中学物理中,涉及到圆周运动的情形有:①地球表面常见的圆周运动;②涉及到万有引力的天体运动(行星绕恒星的运动,卫星绕行星的运动);③涉及到库仑力的微观粒子的圆周运动.本文对前两种情形的复习及相关问题作些分类导析. In the middle school physics, the situations involving circular motions are: 1 The common circular motions on the surface of the earth; 2 The celestial motions involving gravitation (the movement of the planets around the stars, the movement of the satellites around the planets); 3 The microscopic view of the Coulomb force The circular motion of particles. This article makes some classification and analysis of the review of the first two situations and related problems.
