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.

In physics, gravity (), also known as gravitation or a gravitational interaction, is a fundamental interaction, which may be described as the force that draws material objects towards each other.
