Distance & Displacement
Physics: Edexcel IGCSE, topic 1.1.3
Distance vs Displacement
Distance and displacement are slightly different. Be careful which one you use.
Distance
- Distance is how far an object moves.
- Distance is a scalar quantity.
- This is because it contains a magnitude (size) but not a direction.
Displacement
- Displacement is the distance an object moves in a straight line from a starting point to a finishing point.
- Displacement is a vector quantity.
- This is because it contains a magnitude (size) and direction.
