[edit] Physical sciences

[edit] Physics

• Displacement (vector), in Newtonian mechanics, specifies the change in position of a point in reference to a previous position. In simple terms, its the difference between the initial position and the final position of an object
  • Particle displacement, a measurement of distance of the movement of a particle in a medium as it transmits a wave
  • 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

[edit] 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 it out of the way
• 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), several related measurements of a ship's weight
• Displacement mapping, a technique in 3D computer graphics

[edit] Chemistry

• Single displacement reaction, a chemical reaction concerning the exchange of ions
• Double displacement reaction, a chemical reaction concerning the exchange of ions

the reaction making the exchange of ions

[edit] Geology

• Earth Crustal Displacement, also known as "Pole shift"

[edit] Medicine

• Displacement (orthopedic surgery), change in alignment of the fracture fragments

[edit] Linguistics

• Displacement: Languages can be used to communicate ideas about things that are not in the immediate vicinity either spatially or temporally (the out of sight, out of mind concept). One of the properties that separates Human Language from Animal Language.

[edit] Social sciences

• Forced migration, by persecution or violence
• Displacement (psychology), a sub-conscious defense mechanism
• Displacement (psiology, parapsychology, psychical science), a statistical or qualitative correspondence between targets and responses.

[edit] Sport

• Displacement (fencing), a movement that avoids or dodges an attack
