Velocity is described as a vector because which quantity it is built from is a vector?
ATime span
BDisplacement
CTemperature
DMass value
Answer & Solution
Correct answer: B. Displacement
1. A quantity inherits its vector nature from its definition.
2. Average velocity is displacement divided by elapsed time.
3. This definition indicates that velocity is a vector.
4. That is because displacement is a vector.
