# relation of distance to displacement

## Summary

## relation of distance to displacement:

- Distanceis a
*scalar* measure of the interval between two locations measured along the *actual path* connecting them.- As a scalar it has magnitude only.
- Δ
*s*(italic) is the symbol for distance.

- Displacementis a
*vector* measure of the interval between two locations measured along the *shortest path* connecting them.- As a vector it must be stated with both magnitude and direction.
- Δ
**s**(boldface) is the symbol for displacement.

- The origin of the symbols for distance (Δ
*s*) and displacement (Δ**s**) is *spatium*, Latin for space. - The relation of distance to displacement
- The distance traveled to get from one location to another is always greater than or equal to the magnitude of the displacement between the two locations.

#### Δ*s* ≥ |Δ**s**|

- Distance approaches the magnitude of displacement as distance approaches zero.

- The SI unit of distance and displacement is the meter[m].
