Question

Is power scalar or vector?

Answer 1

Scalar and vector quantity

1. Scalar quantities have only a magnitude and do not depend upon any direction.
2. Vector quantities have both the magnitude and the direction.

Power

1. The rate at which work is done on an object is defined as power. $Power=\frac{work\left(energy\right)}{time}$
2. The Joule is the standard metric unit for work and the second is the standard metric unit for time, the standard metric unit for power is a Joule / second, abbreviated $W$.
3. As power doesn’t have any direction, it is a scalar quantity. Also, power is the ratio of two scalar quantities.

Hence, power is a scalar quantity.
