牛顿万有引力定律 Newton's law of universal gravitation

(重定向自Gravitational Force)
两个物体互相吸引
地球重力示意图
地球附近空间内的重力示意图:在此数量级上地球表面的弯曲可被忽略不计,因此力线可以近似地相互平行并且指向地球的中心
球状星团 M13 证明重力场的存在。

万有引力定律 (Newton's law of universal gravitation) 是艾萨克·牛顿在1687年于《自然哲学的数学原理》上发表的。牛顿的普适万有引力定律表示如下:

任意两个质点有通过连心线方向上的力相互吸引。该引力的大小与它们的质量乘积成正比,与它们距离的平方成反比,与两物体的化学本质或物理状态以及中介物质无关。

以数学表示为:F=G\frac{m_1m_2}{r^2}

(更严谨的表达请见下文中的矢量式方程。)

其中:

依照国际单位制,F的单位为牛顿(N),m1m2的单位为千克(kg),r 的单位为米(m),常数G近似地等于6.67 × 10 N m kg(牛顿米的平方每千克的平方)。

Newton's law of universal gravitation 牛顿万有引力定律

(重定向自Gravitational Force)
Gravitational field strength within the Earth
Gravity field near the surface of the Earth – an object is shown accelerating toward the surface
Field lines drawn for a point mass using 24 field lines

Newton's law of universal gravitation states that a particle attracts every other particle in the universe using a force that is directly proportional to the product of their masses but also inversely proportional to the square of the distance between them. This is a general physical law derived from empirical observations by what Isaac Newton called induction. It is a part of classical mechanics and was formulated in Newton's work Philosophiæ Naturalis Principia Mathematica ("the Principia"), first published on 5 July 1687. (When Newton's book was presented in 1686 to the Royal Society, Robert Hooke made a claim that Newton had obtained the inverse square law from him; see the History section below.)
