中学物理中所涉及到的圆周运动大致可分为两类:一类是物体只受主动力(如万有引力、库仑力)作用下的圆周运动,称为无约束圆周运动.如人造地球卫星在地球引力作用下所做的匀速圆周运动;负电荷在库仑力作用下绕固定正电荷所做的匀速圆周运动等.另一类是物体除受主动力外,还受...
The circular motion involved in middle school physics can be roughly divided into two categories: one is that the object is only subjected to the circular motion under the action of the main force (such as universal gravitation and Coulomb force), which is called unconstrained circular motion. For example, the artificial earth satellite is on the earth. Uniform circular motion under the action of gravitational force; the uniform circular motion of a negative charge around a fixed positive charge under the action of the Coulomb force; the other is that the object is subject to subjective power, but also subject to...
