[edit] Physical sciences

[edit] Physics

• Displacement (vector), in Newtonian mechanics, specifies the position of a point in reference to an origin or to a previous position
  • 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

[edit] Geology

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

[edit] Medicine

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

[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
