Answer:

Explanation:

Power: The rate of doing work or the amount of energy transferred is called power. The unit of power is joule per second .

The physical quantity obtained by dot product of force and velocity is Power. It is Scalar quantity.

Proof:

F.v = F.d/t

Which implies,

W/t = P

Where,

F - Force

v - Velocity

As power has no direction and is one dimensional measurement. So, it is regarded as a scalar quantity.
