Would it require less speed to launch a satellite (a) toward the east mk: a*wob+s1 tor (b) top5 v0 wbnxon58ward the west? Consider the Eavp8x05b onnw5rth’s rotation direction.
参考答案:
In order to orbit, a satellite must reach an orbital speed relative to the center of the Earth. Since the satellite is already moving eastward when launched (due to the rotation speed at the surface of the Earth), it requires less additional speed to launch it east to obtain the final orbital speed.
