2.1 REST AND MOTION

AspectDistanceDisplacement
DefinitionLength of the path traveled between two positionsShortest distance from initial to final position
CharacteristicsScalar quantity (no direction)Vector quantity (has direction)
Notation\( \Delta x, \Delta r, \Delta s, \Delta d, \Delta l \)\( \Delta d \)
SI UnitMeter (m)Meter (m)
ExampleTraveling from Faisal Masjid to Blue Area via a twisted pathMoving directly from one point to another
Points to PonderDistance covered on a 400 m track with starting and ending point the same is 400 meters; Displacement is 0 meters.Displacement cannot be greater than distance. Distance and displacement can be equal if the path is a straight line.
