displacement
Let an agent explain displacement as a physical vector, relay its definition, related vectors and units from physics sources, describe the named forms, and distinguish physical displacement from distance travelled, velocity, ship displacement, fluid displacement and psychological displacement.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain displacement as a physical vector, relay its definition, related vectors and units from physics sources, describe the named forms, and distinguish physical displacement from distance travelled, velocity, ship displacement, fluid displacement and psychological displacement.
In physics, a vector quantity describing the change in position of a point, the straight-line distance and direction from an initial to a final position, distinct from the path length travelled, measured in metres; specialised forms the registry aliases name include the displacement vector in mechanics, sound particle displacement and its root-mean-square value in acoustics, the lattice vector describing periodic positions in crystals, and the Burgers vector characterising a dislocation in a crystal. Displacement also has other senses in fluid mechanics, ship tonnage, psychology and geology, which are distinct concepts.
What it is for: Describing change in position.
It can be explain the concept; relay related vectors; describe named forms; distinguish other senses.
Distinguishing features
Vector quantity
Start-to-end, not path
Direction and magnitude
Specialised forms
What it looks like
Not a physical object; an arrow from start to end position in diagrams.
Physical character
SI unit: metre unit
vector or scalar: vector note - has direction
Burgers vector: characterises dislocations note - crystallography
How it is recognised
Vector from initial to final position
Sound particle displacement, lattice vector, displacement vector, Burgers vector, root-mean-square sound particle displacement
Distance travelled is path length; velocity is rate of displacement; ship displacement is weight of water displaced; psychological displacement is a defence mechanism
