Answer 2

║⊕ANSWER⊕║

The amount of energy transferred or converted per unit time is called power.

The SI unit of power is Watt.

1 Watt  is equal to one joule per second.

• Power on its own is defined as being the rate of energy transfer, and it has no additional information as to its direction, so it is a scalar.

Power is energy (or work) per unit time.

Time is not considered a vector quantity, and neither is energy or work — work isn't directional.

So power is the ratio of two scalar quantities, and is thus scalar, not vector.
