In physics, displacement and distance are two crucial concepts. We’ll put your knowledge to the test today with this quiz on displacement and distance. You can test your understanding of distance, and displacement by taking the quiz below. Try it out to see how well you do.

Distance and displacement are the only topics that are used in the questions on this quiz. But students should already know about right-angle triangles and Pythagoras’ theorem, which is used to figure out displacement.

(a) 9 Km, 4 Km

(b) 5 Km, 5 Km

(c) 9 Km, 5 Km

(d) 5 Km, 9 Km

### Important points to remember

- The smallest distance that can be traveled between two positions determines the magnitude of the displacement.
**$distance\geq displacement$** - There can never be zero distance for a moving particle. However, a particle’s displacement can be zero, positive, or negative.
- Zero displacements indicate that, after motion, the particle has returned to its starting position.
- While displacement can decrease over time for a moving object, distance can never do so.
- When displacement lessens over time, the body is returning to its starting position.
