众所周知,由于万有引力定律与日常生活和工农业生产紧密相连,对人造卫星、载人航天和深空探测等高精尖端领域都起着重要的理论支撑作用,它不但是高中物理教学的重点,而且是高考命题的热点,同步地球卫星因为有着不可替代的特殊优势而备受命题人的关注.这类试题多以理 It is well-known that as the law of gravity is closely linked to daily life and industrial and agricultural production, it plays an important theoretical support role in high-precision fields such as satellite, manned spacecraft and deep space exploration. It is not only the focus of high school physics teaching, but also Is the hot topic of college entrance examination, synchronous satellite because of the irreplaceable special advantages and much propositions attention.
