Which quantity has both magnitude and direction?

• A. Vector
• B. Scalar
• C. Mass
• D. Time

Answer: (A)

Quantities that have both magnitude and direction are vectors. The magnitude is how much there is, and the direction tells which way it acts. A vector can be drawn as an arrow where the length represents magnitude and the arrow points in its direction, or described by components along axes. In sports science, examples include velocity (how fast and in which direction an athlete moves), displacement (overall change in position), and force (the push or pull in a specific direction). Scalars, on the other hand, have only magnitude; mass and time are classic examples. So the quantity that has both magnitude and direction is a vector.
