在普通高中课程标准实验教科书必修物理2第六章第二节《太阳与行星间的引力》中太阳与行星间的引力是这样进行推导的:一、太阳对行星的引力根据开普勒行星运动第一、第二定律,行星以太阳为圆心做匀速圆周运动。太阳对行星的引力,就等于行星做匀速圆周运动 The gravitation between the sun and the planet in the ordinary high school curriculum standard experimental textbook Compulsory Physics 2, Chapter 6, Section 2, “The Gravitation Between the Sun and Planets” is deduced as follows: 1. The gravitational pull of the Sun on the planet is determined by Kepler’s planetary motion The first and second laws, the planets do a constant circular motion with the sun as its center. The sun’s gravitational pull on the planet is equal to the planet’s uniform circular motion
