作为中学唯一涉及并用以讨论天体运动问题的万有引力定律,被物理教学大纲和考试说明列为教学及考核的重点内容之一。诚然,万有引力定律这一章的知识点并不多。但是,需要用这个定律处理的习题题型多、综合性强,学生处理这类问题时普遍感到困难,这无疑增加了复习难度。 As the only high school law of gravity involved in and used to discuss the movement of celestial bodies, it was listed as one of the key contents of teaching and assessment by physics syllabus and examination description. It is true that the chapter on the law of gravity does not have much knowledge. However, the types of problems that need to be dealt with by this law are many and comprehensive, and students generally feel difficult when dealing with such problems, which undoubtedly increases the difficulty of review.
