摘　　要：从2021年上海市一道物理高考题说起,简单叙述通过单摆测量万有引力常量G的历史.从最早17世纪牛顿提出想法,接着18世纪的榭赫伦实验,到最近的双单摆F-P腔法,简略向读者介绍单摆测G的发展历程.Starting from a physics college entrance examination question in Shanghai in 2021,this paper briefly describes the history of measuring the universal gravitational constant G using simple pendulum.From Newton′s idea in the 17th century,the Scherren experiment in the 18th century,to the recent double simple pendulum F-P cavity method,it briefly introduces the development process of measuring G with single pendulum.

关 键 词：高考 单摆 万有引力常量
