Displacement may refer to:
Physical sciences
Mathematics and physics
-
Displacement (geometry), is the difference between the final and initial position of a point trajectory (for instance, the center of mass of a moving object). The actual path covered to reach the final position is irrelevant.
-
Particle displacement, a measurement of distance of the movement of a particle in a medium as it transmits a wave (represented in mathematics by the lower-case Greek letter ΞΎ)
-
Displacement field (mechanics), an assignment of displacement vectors for all points in a body that is displaced from one state to another
-
Electric displacement field, as appears in Maxwell's equations
-
Wien's displacement law, a relation concerning the spectral distribution of blackbody radiation
-
Angular displacement, a change in orientation of a rigid body, the amount of rotation about a fixed axis.
Engineering
-
Engine displacement, the total volume of air/fuel mixture an engine can draw in during one complete engine cycle
-
Displacement (fluid), an object immersed in a fluid pushes the fluid out of the way
-
Positive displacement meter, a pump or flow meter which processes a definite fluid volume per revolution
-
Displacement has several meanings related to ships and boats
-
Displacement hull, where the moving hull's weight is supported by buoyancy alone and it must displace water from its path rather than planing on the water's surface
-
Displacement speed, a rule of thumb for non planing watercraft to estimate their theoretical maximum speed
-
Displacement (ship), the weight of a ship
-
Insulation displacement connector, a type of electrical connector
-
Displacement mapping, a technique in 3D computer graphics
Chemistry
-
Single displacement reaction, a chemical reaction concerning the exchange of ions
-
Double displacement reaction, a chemical reaction concerning the exchange of ions
-
Radioactive displacement law of Fajans and Soddy, elements/isotopes created during radioactive decay
Geology
-
Earth Crustal Displacement, an aspect of the Pole shift hypothesis
Medicine
-
Displacement (orthopedic surgery), change in alignment of the fracture fragments
Social sciences
-
Displacement (linguistics), the ability of humans (and possibly some animals) to communicate ideas that are remote in time and/or space
-
Forced displacement, by persecution or violence
-
Displacement (psychology), a sub-conscious defense mechanism
-
Displacement (parapsychology), a statistical or qualitative correspondence between targets and responses.
-
Development-induced displacement, the displacement of population for economic development
-
Displacement may occur during gentrification.
