历年高三复习到天体运动这章内容时,学生总是分不清近地卫星、同步卫星以及在地球赤道上跟随地球一起自转的物体这三个不同模型的圆周运动参量间的关系。对于这里的一套公式,由GMmr2=ma=mvr2=mω2r=m4Tπ22r解得的一组结论a=GMr2,v=GrM,ω=GrM3,T=2πr3GM不知道什么时候可以用, During the third year of the third year review of the celestial body movement, the students could not tell the relationship among the three different models of the circular motion parameters of near-earth satellites, geosynchronous satellites, and objects that orbited the earth along the Earth’s equator. For a set of formulae here, a set of conclusions solved by GMmr2=ma=mvr2=mω2r=m4Tπ22r a=GMr2, v=GrM, ω=GrM3, T=2πr3GM do not know when it can be used,
