Which of the following quantities is not a vector?
Correct answer: D. Distance
- A. Velocity
- B. Force
- C. Displacement
- D. Distance
Explanation
The correct answer is Option D: Distance. Scalars are quantities that have only magnitude, such as distance. Vectors, on the other hand, have both magnitude and direction, like velocity, force, and displacement. Therefore, distance is not a vector because it lacks directional information, unlike the other options provided.

About Force and Motion
Displacement, velocity and acceleration describe motion, including the horizontal and vertical components of projectile motion. The chapter connects these quantities with Newton's laws, momentum and impulse, then applies conservation of momentum to collisions, distinguishing elastic collisions from inelastic ones.
