 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(X₁ Y₁) and (X₂ Y₂) or assumed to be in space where they are defined by (X₁, Y₁, Z₁) and (X₂, Y_2, Z₂) the distance between them can be determined by applying this relation.

OR

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

1. What is displacement and why is it regarded as vector quantity?
   
2. Highlight three differences between distance and displacement
