万有引力是自然界最普遍的规律之一,所有有质量的物体间都有万有引力,在一般情况下万有引力微不足道,只有在天体与一般物体之间,或者天体之间才有意义,作为中学唯一涉及并用于讨论天体运动问题的万有引力定律,是高考的一个重点内容,几乎每年都考。万有引力定律知识点不多,而且思路简单,即把天 Gravitation is one of the most common laws in nature. All mass objects have gravitational attraction. In general, gravitation is insignificant. It is only meaningful between celestial bodies and general objects, or between celestial bodies. The law of universal gravitation that discusses the movement of celestial bodies is a key content of the college entrance examination. It is tested almost every year. There is not much knowledge of the law of gravity, and the idea is simple:
