Physical sciences

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

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

Chemistry

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

Geology

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

Medicine

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

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

Sport

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

See also

• Offset (disambiguation)

In Physics, displacement is the vector that specifies the position of a point or a particle in reference to a previous position or to the origin of the chosen Particle displacement or particle amplitude (represented in Mathematics by the lower-case Greek letter &xi) is a Measurement A displacement field is an assignment of displacement vectors for all points in a body that is displaced from one state to another In Physics, the electric displacement field (also called electrical field/flux density is a Vector field \mathbf{D} that appears in Maxwell's equations Engine displacement is defined as the total Volume of air/fuel mixture an Engine can draw in during one complete engine cycle it is normally stated in Cubic In Fluid mechanics, displacement occurs when an object is immersed in a Fluid, pushing it out of the way and taking its A hull is the body of a Ship or Boat. It is a central concept in floating vessels as it provides the Buoyancy that keeps the vessel from sinking Hull speed, sometimes referred to as displacement speed, is a Rule of thumb used to provide an approximate maximum efficient speed for a hull A ship's displacement is its mass at any given time generally expressed in metric tons or Long tons The term is often used to mean the ship's mass when it is loaded Displacement mapping is an alternative computer graphics technique in contrast to Bump mapping, Normal mapping, and Parallax mapping, using a ( procedural A single-displacement reaction, also called single-replacement reaction, is when an element or ion moves out of one compound and into another Metathesis is a bimolecular process involving the exchange of bonds between the two reacting Chemical species, which results in the creation of products with similar Displacement in Orthopedic surgery refers to change in alignment of the Fracture fragments Forced migration (also called deracination) refers to the coerced movement of a person or persons away from their Home or home Region. In Psychology, displacement is an Unconscious Defense mechanism whereby the mind redirects affects from an object felt to be dangerous or unacceptable Displacement is a characteristic quality of psi, or anomalous cognition In Fencing, a displacement is a movement that avoids or dodges an attack In Mathematics, a transformation could be any Function from a set X to itself
