OverviewAI-generated

Gravity is a fundamental interaction and physical phenomenon. It is distinct from gravitational force, Gravity, Gravitation, and gravity of Earth. The subject has effects such as fall and is caused by spacetime curvature and matter. Its characteristics include gravitational force and spacetime curvature.

Isaac Newton is a discoverer or inventor associated with gravity. The phenomenon is studied by Newton's law of universal gravitation and general relativity. It is described by sources including the Brockhaus and Efron Encyclopedic Dictionary, Encyclopædia Britannica 11th edition, Tietosanakirja, and Pieni tietosanakirja.

The topic appears in the Commons category "Gravitation" and the main category Category:Gravity. It is referenced by 2,812 other encyclopedia articles. PubMed lists a count of 50,148 for the query gravity. It is on the focus lists for Wikipedia:List of articles all languages should have and Wikipedia:Vital articles/Level/4.

重力（英語：gravitation/gravity），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、弱相互作用及强相互作用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，引力现象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，月球以及太陽对地球上海水的引力，形成了地球上的潮汐。
