在利用万有引力定律解决物理问题时,由于解答的问题类型多,公式繁琐,记忆困难,容易发生错误.但是我们只要抓住这类问题的处理方法也就容易解答了.这类问题的处理方法是:第一:抓住万有引力定律的适用条件;第二:天体的运动视为匀速圆周运动,即F引=F向;第三:将运动学和动力学知识迁移到其他天体;第四:利用牛顿运动定律和万有引力定律公式相结22
When using the law of universal gravitation to solve physical problems, we can easily solve the problem because of the many types of problems we solve, the complicated formulas, the memory difficulties and the mistakes, but we can easily solve the problem by just grasping such problems : First: to seize the applicable conditions of the law of universal gravitation; second: the celestial movement as a uniform circular motion, that is, F = F; Third: the kinematics and kinetics of knowledge transfer to other celestial bodies; Fourth: Newton’s Law of Motion and the Law of Gravitation Laws 22
