How is power defined?
a. the quantity of work accomplished
b. the direction of the work
c. the total distance an object is moved
d. the rate at which work is accomplished

The correct answer to this question is D) The rate at which work is accomplished.

EXPLANATION:

Let us consider a body performs W amount of work due to the application of some external forces.

Let the body does that work during the time interval of t seconds.

Hence, the power of the body is defined as the rate of doing work or the work done per unit time. We know that energy is the capacity to do work. So, power can be defined as the rate of consumption of energy.

Mathematically power can be written as -

                              Power P = .

Hence, the correct definition of power is that the rate at which work is accomplished.
