name the physical quantity which is expressed as a dot product of force and velocity? is it scalars or vector?
Answers
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.
