The Concept of Position
The position of an object is its location in space. It is usually expressed in relation to a reference point. To locate an object in space, a co-ordinate system is needed. It is usually a mathematical construct with co-ordinates.
A coordinate system could be two-dimensional as in P(x,y) or three dimensional as in P(x,y,z).
The Concept of Distance and Measurement
Distance can be defined as a physical measurement of length between two points. It does not take into consideration the direction between the two points it measures; hence, it is a scalar quantity. This therefore means that distance has only magnitude but no direction. E.g, 10km.
Distance could be measured using instruments like measuring tape, ruler, venier calliper, micrometer screw gauge, etc.
The Concept of Displacement
Displacement is defined as the distance travelled or moved in a specific direction.
