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 ...
Displacement is the shift in location when an object in motion changes from one position to another. [2] For motion over a given interval of time, the displacement divided by the length of the time interval defines the average velocity (a vector), whose magnitude is the average speed (a scalar quantity).
Electric displacement field. In physics, the electric displacement field (denoted by D) or electric induction is a vector field that appears in Maxwell's equations. It accounts for the electromagnetic effects of polarization and that of an electric field, combining the two in an auxiliary field. It plays a major role in topics such as the ...
A displacement field is a vector field of all displacement vectors for all particles in the body, which relates the deformed configuration with the undeformed configuration. It is convenient to do the analysis of deformation or motion of a continuum body in terms of the displacement field, In general, the displacement field is expressed in ...
Motion is mathematically described in terms of displacement, distance, velocity, acceleration, speed, and frame of reference to an observer, measuring the change in position of the body relative to that frame with a change in time. The branch of physics describing the motion of objects without reference to their cause is called kinematics ...
Mechanics (from Ancient Greek: μηχανική, mēkhanikḗ, lit. "of machines ") [1][2] is the area of physics concerned with the relationships between force, matter, and motion among physical objects. [3] Forces applied to objects result in displacements, which are changes of an object's position relative to its environment.
In electromagnetism, displacement current density is the quantity ∂D/∂t appearing in Maxwell's equations that is defined in terms of the rate of change of D, the electric displacement field. Displacement current density has the same units as electric current density, and it is a source of the magnetic field just as actual current is.
In mechanics, a displacement field is the assignment of displacement vectors for all points in a region or body that are displaced from one state to another. [1][2] A displacement vector specifies the position of a point or a particle in reference to an origin or to a previous position. For example, a displacement field may be used to describe ...
