可汗学院:物理

There will always be some minuscule ones, but we'll assume no gravitational interactions.

其实,总有微小的重力作用,但是,我们假设,没有重力作用。

宇宙奥秘

However, the main cause of this problem is not at all in the gravitational interaction with the earth.

然而,这个问题的主要原因根本不在于与地球的引力相互作用。

引力 Gravity

地球引力场中的引力探测器B
万有引力使行星按照自身的轨道围绕太阳运转
引力源附近扭曲的时空

引力英语:GravitationGravity),又称万有引力英语:Universal Gravitation),是指具有质量的物体之间相互吸引的作用,也是物体重量的来源。

引力与电磁力、弱相互作用力及强相互作用力一起构成自然界的四大基本相互作用。在这四种基本相互作用中,引力是最弱的一种,但同时也是一种长程有效作用力。在现代物理学中,引力一般由广义相对论来精确描述,认为引力反映了物体的惯性在弯曲时空中的表现。而经典力学中的牛顿万有引力定律则是对引力在通常物理条件下的极好的近似描述。

在地球上,地球对地面附近物体的万有引力赋予了物体的重量,并使物体落向地面。在宇宙中,引力让物质聚集而形成天体,同时也让天体之间相互吸引,形成按照轨道运转的天体系统。此外,月球以及太阳对地球上海水的引力,形成了地球上的潮汐。

Hammer and feather drop: Apollo 15 astronaut David Scott on the Moon enacting the legend of Galileo's gravity experiment. (1.38 MB, ogg/Theora format).
Sir Isaac Newton, an English physicist who lived from 1642 to 1727
Two-dimensional analogy of spacetime distortion generated by the mass of an object. Matter changes the geometry of spacetime, this (curved) geometry being interpreted as gravity. White lines do not represent the curvature of space but instead represent the coordinate system imposed on the curved spacetime, which would be rectilinear in a flat spacetime.
Ball falling freely under gravity. See text for description.

Gravity or gravitation is a natural phenomenon by which all things with energy are brought toward (or gravitate toward) one another, including stars, planets, galaxies and even light and sub-atomic particles. Gravity is responsible for many of the structures in the Universe, by creating spheres of hydrogen — where hydrogen fuses under pressure to form stars — and grouping them into galaxies. On Earth, gravity gives weight to physical objects and causes the tides. Gravity has an infinite range, although its effects become increasingly weaker on farther objects.
