高管海底 说的对, 在此我做下补充! 将卫星送到某一高度的轨道.卫星必须具有一定的速度,在这一高度卫星受到的万有引力提供向心力.速度达到一定值, 使得万有引力刚好提供向心力这样就能 持续的围绕地球运动下去. 而这一速度 是很惊人的,很大 的速度. 理想值是7.9km/s,指的是贴近地球表面飞行, 这是不可能的. 实际的卫星速度都小于这个速度, 而考试的时候考的是739km/s.同学必须搞清楚这个知识点的含义!请多做练习题 慢慢总结! 所谓坐地日行三万里.地球自转也有线速度. 所以发射卫星时,人类尽量利用这个线速度 来帮助卫星获得第一宇宙速度7.9km/s, 所以尽量在低纬度地区. 即赤道附近发射. 而 我过 由于地理条件,军事局限所以在海南地区没有发射基地.

题目意思是问:研究火箭以怎样的相对速度方向发射将他们送入太空,解释使用特定的方向发射火箭的好处 。
回答:发射速度方向跟地球自转方向相同
