摘要
从牛顿运动方程解出了落体偏东的精确值，并指出北半球的自由落体除有偏东外，还有偏南情形。结果表明：偏南值仅与地球自转角速度Ω的平方有关；偏东值则与Ω的一次方和三次方有关。
The precise value of the eastward drift of a free-falling body can be drawn from Newtonian dynamical equation,This paper points out that a free-falling body in the northern hemisphere will drift not only to the east but also to the south. The solution shows that the southward drift has on ly second-order effect of the angular velocity Ω of rotation of the earth, while the eastward drift has first-order and third-order effect of Ω.
