Displacement

Explanation:

Displacement is the vector quantity that defines distance and direction between two positions.

Displacement talks about distance covered in a specified direction. Displacement is example of vector quantity because "it specifies direction" compare to distance that doesn't. Vector quantity is a quantity that has both magnitude and direction. Therefore anytime displacement is being calculated, the direction of movement of the body has to be specified e.g A body moves 8m in the direction is N45°E. That N45°E serves as the direction.
