处理天体运动的问题主要有两大前提,一是对环绕天体做受力分析,我们这里研究只受中心天体万有引力作用的环绕天体;二是对环绕天体做运动分析,我们这里研究环绕天体做匀速圆周运动。那么,我们如何入手处理只受中心天体万有引力作用的,环绕天体做圆周运动的问题呢?只在中心天体的万有引力作用下,
There are mainly two major prerequisites for dealing with celestial movement. One is to analyze the forces around the celestial bodies, and here we study the celestial bodies that are only subject to the gravitational attraction of the central celestial body. The other is the analysis of the movement around the celestial bodies. Circular motion. So, how do we deal with the problem of circular motion around the celestial body only by the universal gravitation of the celestial body? Only under the universal gravitation of the central celestial body,
