Which of the following is a vector quantity?
Correct answer: C. Displacement
- A. Speed
- B. Distance
- C. Displacement
- D. Time
Explanation
Displacement has both magnitude and direction, whereas distance records only how far was travelled with no direction attached. Speed is the scalar partner of velocity, and time has no direction at all. This is why a runner completing a circular track has covered a large distance but has zero displacement.

About Displacement and Velocity
Displacement is the directed change in position, while velocity is the rate of change of displacement and includes both magnitude and direction. The topic connects position-time and velocity-time graphs with average and instantaneous values, and distinguishes displacement from distance and velocity from speed.
