万有引力定律和牛顿运动定律、圆周运动、天体运动联系紧密,牵涉知识面广,综合性较强,是考查学生综合运用知识分析问题的较好内容。对万有引力定律,高考试题深入分析的大致分为两大类。第一类是直接运用万有引力提供物体作为圆周运动的向心 The law of universal gravitation is closely related to Newton’s law of motion, circular motion and celestial movement, involving a wide range of knowledge and strong comprehensiveness. It is a good content for examining students’ comprehensive use of knowledge analysis. The law of gravity, entrance examination questions in-depth analysis can be broadly divided into two categories. The first category is the direct use of gravitation to provide objects as centripetal motions
