万有引力定律与天体问题是历年高考必考内容,考查形式多以选择题型出现。本部分内容常以天体问题(如双星、黑洞、恒星的演化等)或人类航天(如卫星发射、空间站、探测器登陆等)为背景,考查向心力、万有引力、圆周运动等知识。这类以天体运动为背景的题目,是近几年高考命题的热点,特别是近年来我们国家在航天方面的迅猛发展,更会出现各类天体运动方面的题。笔者根据多年的教学实践,对其进行归纳整理发现,天体运动背景知识复杂,求解参量众多,向心
The law of universal gravitation and the celestial body problem are the contents of the exams that will be taken in the past years of college entrance examination. The forms of examinations are mostly multiple choice questions. In this section, knowledge of centripetal force, universal gravitation, and circular motion is often examined against the background of celestial bodies (such as binary stars, black holes, evolution of stars, etc.) or humankind (such as satellite launches, space stations, and detector landed) This kind of subject with celestial movement as the background is the hot topic of the college entrance examination in recent years. Especially in recent years our country has witnessed rapid development in space and space, and more problems in celestial movement will emerge. Based on many years of teaching practice, the author summarizes and finds out that there are complex background knowledge of celestial bodies and many parameters to solve
