Displacement. It is the action and effect of displacing. This verb has various uses, such as moving (going from one place to another) and moving or removing someone or something from the place where they are.

  • 1 Displacement can refer to:
  • 2 Path vs. displacement
    • 1 Trajectory
    • 2 Displacement
  • 3 Sources

Displacement may refer to:

  • Displacement, in physics, is the length of the path between the initial position and the final position of a material point. A particular case of displacement is due to diffusion.
  • Displacement, in nautical, is the weight of the water displaced by the submerged part of the hull of a ship .

In sailing, displacement is the volume and weight of the water that a ship displaces and which is equal to the space that its hull occupies up to its waterline. This is based on the Archimedean principle , a physical principle that holds that a body totally or partially submerged in a static fluid , will be pushed with a force equal to the weight of the volume of fluid displaced by said object.

The units used to measure displacement are meters and tons . It can be referred to as a displacement in thread (the weight of the ship as delivered by the shipyard: without fuel , supplies, provisions or crew, displacement in ballast (the weight of the ship in thread plus everything necessary for it to navigate, but without load) and maximum displacement (the weight a ship achieves when submerged to the maximum load line).

  • Displacement, in psychoanalysis is the transfer of emotions towards a human or animal being that is not the real object of the anger of the one who displaces his affections.

For psychology , displacement is an unconscious defense mechanism , in which the mind redirects some emotions from an object or psychic representation that is perceived as dangerous or unacceptable towards an acceptable one.

  • Internal displacement means forced migration within the same country.

It refers to those people who are forced to flee their homes due to a crisis but who, unlike refugees, remain within the borders of their country of origin.

Path vs. displacement

The change in position of an object leaves a trail on the background in which it moves that marks its path. The path, in physics , can be represented by two different magnitudes : trajectory and displacement .


The succession of points that the mobile passed through on its route is called a trajectory, and its value in the International System is that distance, measured over the trajectory, normally irregular, in meters.


Displacement is called the distance in a straight line between the starting and ending position. It is represented by a vector with its characteristics: module-distance in meters-, direction- that of the line, direction -from start to end-, point of application-start-.
