Scalars and vectors — practice question

The equation below gives the power generated when a force causes an object to move. $\text{power} = \frac{\text{work}}{\text{time}} = \frac{\text{force} \times \text{displacement}}{\text{time}}$ Which of these quantities are scalars, and which are vectors?

  • Ascalars: displacement, time; vectors: force, power
  • Bscalars: power, work; vectors: displacement, force
  • Cscalars: power, force; vectors: displacement, work
  • Dscalars: work, time; vectors: power, displacement
