(i) Displacement is a vector quantity as it possesses both magnitude and direction.
(ii) Displacement of a body in a given time is represented by a vector drawn from the initial position to its final position.
(iii) The unit of displacement is that of length.
(iv) The value of displacement can be positive, zero or negative.
(v) The value of displacement can never be greater than the distance travelled.
