在人造卫星发射能量的相关计算中,一般有两种不同的计算方法,一种是选择以地面为参照物,另一种是选择以地心为参照物,从而我们会得出两种截然不同的结果.可是,发射卫星时消耗燃料的能量应该是一个定值,它与参照物的选择没有关系.下面首先就让我们一起来欣赏这两种不同的能量计算方法.题目在赤道上发射两颗质量均为 M 沿赤道正上方圆形近地轨道绕地心做圆周运动的卫星 A 和 B,A 向正东方发射,
There are generally two different calculation methods for calculating the launch energy of satellites. One is to select the ground as the reference, and the other is to choose the geocentric as the reference object, so we will come to two very different ways. The result, however, is that the energy used to burn the satellite should be a fixed value. It has nothing to do with the choice of the reference. Let’s start by enjoying the two different methods of energy calculation. Topic Launch on the Equator The masses are all satellites A and B orbiting the earth in a circular near-earth orbit directly above the equator, and A is launched towards the east.
