## POSITION

The position of an object in space or on a plane is the point at which the object can be located with reference to a given point (the origin).

## DISTANCE

This is a measure of the separation between two points. It has magnitude but no direction. Hence, it is a scalar quantity

## DETERMINATION OF DISTANCE BETWEEN TWO POINTS

If two points A and B located in a plane are defined by two ordered pair of values(X_{1} Y_{1}) and (X_{2} Y_{2}) or assumed to be in space where they are defined by (X_{1}, Y_{1}, Z_{1}) and (X_{2}, Y_{2,} Z_{2}) the distance between them can be determined by applying this relation.

## DISPLACEMENT

Displacement is the distance covered in a specified direction. It is a vector quantity, which has the same unit as distance.
