alleryStart learning →Velocity is a vector quantity because it is defined using:
ADistance, itself a vector
BTime, itself a vector
CMass, itself a vector
DDisplacement, itself a vector
Answer & Solution
Correct answer: D. Displacement, itself a vector
1. A quantity built from a vector inherits its direction.
2. Average velocity is displacement divided by elapsed time.
3. This definition indicates that velocity is a vector because displacement is a vector.
4. Time and mass are scalars, so neither could supply the direction.
