Distance

Displacement

Length of a path between two points is called the distance between those points. 

Displacement is the shortest distance between two points which has magnitude and direction. 

Distance is a scalar quantity.

Displacement is a vector quantity.

Distance is denoted by “S”

                S = vt

Its SI unit is meter (m).

Displacement is denoted by “d”

                   D = vt

Its SI unit is metre (m).

Distance S (dotted line) and displacement d(dark line) from points A to B,
