Power is defined as the rate at which work is done upon an object. Power is a time-based quantity. Which is related to how fast a job is done. The formula for power is given below.
Power = Work / time
P = W / t
Unit of Power
The unit for standard metric work is the Joule and the standard metric unit for time is the second, so the standard metric unit for power is a Joule / second, defined as a Watt and abbreviated W.
Vector of scalar?
As power doesn’t have any direction, it is a scalar quantity. Also, power is the ratio of two scalar quantities.
