This is known as the Cavendish experiment, in honor of H. Cavendish, who achieved the first reliable results by this method in 1797–1798. More recent determinations using various refinements yield the results: constant of gravitation G = 6.67 × 10-11 SI (mks) units; mass of Earth = ...
As one knows, strong discrepancies are found between the different precise measurements of the gravitational constant carried out in Earth-based laboratories. While the precision is increasing in different laboratories and with various methods, these measurements are even more and more discordant. We ...

The formulation of Newton’s law of gravitation involving the gravitational constant did not occur until the late 19th century. The experiment was originally devised to determine Earth’s density, which Cavendish determined to be 5.48 grams per cubic centimetre—close to the modern value of 5.51 ...

of gravity force是指重力的平方反比特性，即距离越远，互相引力越小。下文是指把无穷远处作为参照点，那么重力作用为0（r趋近无穷大，r^2也是，引力趋近为0）。而且由于当物体接近地球（以地球为例），引力做正功（移动方向与力的方向一致），那么可以把近地处的重力能量设为负值（0-正值）。
