Gravity displacement is not a standard term in physics. The phrase is used informally to describe the vertical or spatial change of a body under gravitational influence, or more generally to refer to gravity-related distortions in systems. Because it does not have a universally agreed definition, discussions of gravity displacement typically specify the context, whether Newtonian motion, spacetime curvature, or gravitational loading of materials.

In Newtonian mechanics, displacement due to gravity refers to the vertical movement of a body under acceleration g. If an object is released from rest at position s0, its height as a function of time is s(t) = s0 + 0.5 g t^2, neglecting other forces. This sort of displacement is routine in introductory physics, engineering, and experiments that measure free fall or height changes.

In the general theory of relativity, gravity is not a force but the curvature of spacetime. The relative displacement of nearby free-falling test masses is described by geodesic deviation, while time-varying gravitational fields can cause oscillatory displacements in the presence of gravitational waves. In this sense, gravity displacement can be framed as the observable change in position caused by spacetime curvature or waves, rather than by a direct force.

In geophysics and civil engineering, gravity can induce notable displacements through vertical loading, subsidence, tides, and crustal deformations. Models of gravity-induced displacement are used to study Earth tides, fluid pressure effects, and the response of structures to weight changes.

Quantitative study of gravity-related displacement relies on precise sensors such as gravimeters and laser interferometers, and is subject to noise from seismic activity, temperature variation, and local mass changes.

The term gravity displacement remains informal and context-dependent; authors typically replace it with more precise terms such as gravitational displacement, gravitational settling, geodetic displacement, or geodesic deviation depending on the topic.
