The displacement has _.
Correct answer: C. Magnitude and direction
- A. Magnitude only
- B. Direction only
- C. Magnitude and direction
- D. No unit is required
Explanation
Option A) Magnitude only is incorrect because displacement does not just include the magnitude or amount of the change in position, but also includes information about the direction of the change.Option B) Direction only is also incorrect because displacement does not just include the direction of the change in position, but also includes information about the magnitude of the change.Option C) This is because displacement is a vector quantity. A vector quantity has both magnitude and direction. Option D) No unit is required is incorrect because displacement has units of length (e.g. meters, feet, etc.), just like other vector quantities such as velocity and acceleration.

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.
