笔者在十几年的高中物理教学生涯中,闲暇之余喜好对各种高中物理教学资料中的数据及观点进行考究思考。认为有时资料中的观点数据也未必正确,现就有关月亮的引力问题和同步卫星的相对静止的问题提出一些自己的想法。供各位高中物理教师同行们参考。在高中阶段学习牛顿万有引力定律时,为了佐证引力的大小与距离的平方成反比,往往用太阳、地球对月亮的引力大小来比较。
During my career in high school physics teaching for more than ten years, I spent my free time studying and thinking about the data and viewpoints of various high school physics teaching materials. It is considered that sometimes the data on the viewpoints in the data may not be correct. Some ideas on the gravitational problems of the moon and the relative quiescence of the geostationary satellites are proposed. For your high school physics teachers counterparts. When studying Newton’s law of gravitation in high school, in order to prove that the magnitude of gravitation is inversely proportional to the square of the distance, it is often compared by the magnitude of the sun and the earth’s gravity to the moon.
