What is the difference between displacement and distance?
What is the difference between displacement and distance?
- Displacement is a vector quantity, while distance is a scalar quantity.
- Displacement is the change in position of an object, while distance is the total length of the path traveled between two positions. (correct)
- Displacement is the total length of the path traveled between two positions, while distance is the change in position of an object.
- Displacement is a scalar quantity, while distance is a vector quantity.

Study Notes
Scalar and Vector Quantities
- Scalar quantity: a physical quantity with only magnitude (amount or size)
- Vector quantity: a physical quantity with both magnitude and direction
Displacement and Distance
- Displacement: the shortest distance between the initial and final positions of an object
- Distance: the total length of the path traveled by an object
- Difference: displacement is a straight-line distance, while distance is the total distance traveled
Example Problems
- Displacement of a cyclist who rides 3 km west and then turns around and rides 2 km east: 1 km west (since the cyclist ends up 1 km west of the starting point)
- Total distance a person walks: 30.0 m (20.0 m + 10.0 m)
