高中物理中的双星,三星,多星系统是非常重要的内容,也是一种自然的天文现象,天体之间的相互作用遵循牛顿万有引力规律,他们的运动规律也同样遵循开普勒行星运动的三条基本规律.关于双星、三星系统的等效质量的计算,运行周期的计算等都是以万有引力提供向心力为出发点的.一、双星问题1.要明确双星中两颗子星做匀速圆周运动的向心力来源双星中两颗子星相互绕着旋转可看作匀速圆周运动,其向 The binary, samsung and multi-satellite system in high school physics is a very important part as well as a natural astronomical phenomenon. The interaction between celestial bodies follows Newton’s law of universal gravitation, and their laws of motion follow the same three principles of Kepler’s planetary motion The basic law The binary system, the Samsung system equivalent mass calculation, the calculation of the operating cycle and so on is the gravitation to provide centripetal force as a starting point .One, double star problem 1 should be clear double star in the two stars to do uniform circular motion centripetal force The two binary stars in the source binaries rotate around each other, which can be regarded as a uniform circular motion
