displacement

from: one point in space to another

is: the change in position from the first point to the second. [P2.1]

is represented: by a vector. The displacement from a point with position vector to a point with position vector is given by [P2.2]

has magnitude: equal to the distance between the two points. [P2.2]

has direction: along the line from the first point to the second. [P2.2]

may be measured: from any selected reference point, unlike a position vector. [P2.2]

has as its SI unit: the metre (m). [M2.4]

in one dimension can be represented: by a single scalar component If the selected reference point is at the initial position of the particle, then the displacement of the particle at time is [M4.1, P2.1]

in linear motion is given: for displacement of an object from its position at time to its position at time by the area under the corresponding velocity-time graph between and [M5.1]
