Displacement at constant velocity
Displacement is signed; distance is the length of the path.
The key idea
Displacement is signed; distance is the length of the path.
Δx = vΔt
Worked examples
An object moves at constant velocity 15 m/s for 16 s. Find displacement in m.
15 × 16 = 240
240 m
An object moves at constant velocity -13 m/s for 34 s. Find displacement in m.
-13 × 34 = -442
-442 m
Try it yourself
An object moves at constant velocity 17 m/s for 39 s. Find displacement in m.
An object moves at constant velocity 28 m/s for 21 s. Find displacement in m.

Answers and marking notes
- 663 m
17 × 39 = 663
- 588 m
28 × 21 = 588
