Question

Is power a scalar quantity or a vector quantity?

Answer 1

1. Power is defined as the rate of doing work.
2. It is also defined as the amount of energy transferred or converted per unit time.
3. Power depends upon the amount of work done and the time or which work has been done.
4. Hence, the expression of power is given by $Power=\frac{Workdone}{time}$.
5. Power is a scalar quantity as it has only magnitude, not direction.
