高中物理课本必修2(人教版新课标实验教科书)中有一幅极易引起误解的插图.在该书的第71页有如下内容:“牛顿得出了万有引力与物体质量及它们之间距离的关系,但却无法算出两个天体间万有引力的大小,因为他不知道引力常量 G 的值.一百多年以后,英国物理学家卡文迪许(Henry Cavendish,1731-1810)在实验室里通过几个铅球之间万有引力的测量,比较精确地得出了 G的数值.”紧接着课本中给出了一幅插图,并配有这样的说
There is a highly misunderstood illustration in High School Physics Textbook Compulsory 2 (Pioneer New Curriculum Standards Textbook). On page 71 of the book there is the following: “Newton has drawn the gravity and quality of objects and their The relationship between distances, but it can not calculate the size of the gravitation between two objects, because he does not know the value of the gravitational constant G. More than 100 years later, the British physicist Henry Cavendish (1731-1810) in the experiment In the room, through the measurement of gravitation between several shot balls, the value of G was obtained more accurately. ”An illustration was given immediately after the textbook and it was
