在高中物理学习中,学生碰到天体问题时常常有惧怕心理,要么是找不到关键的切入点而无从下手,要么是看不出题目所给的已知条件和所提问题之间的联系。对于一般的高中物理天体问题,笔者做了一些总结,发现高中物理天体问题大致可分为两大类。一、环绕问题环绕天体围绕中心天体运动的问题一般由万有引力充当向心力,表达式为F=F n。在这里,万有引力的公 In high school physics study, students often have fear of encountering celestial bodies, either can not find the key entry point and can not get started, or can not see the relationship between the given conditions given and the questions raised . For the general problem of high school physics celestial bodies, the author made some conclusions and found that the problems of high school physics celestial bodies can be broadly divided into two categories. First, the issue of surround Surrounding celestial bodies around the center of the celestial movement problem is generally centripetal force acting as a centripetal force, the expression F = F n. Here, the gravitation of the public
