Final answer:

Power in physics is the rate at which work is done, measured in watts.


Explanation:

Power is the rate at which work is done, measured in watts (W), representing work done per unit time. It is the measure of how rapidly work is done, calculated as the derivative of work with respect to time. Efficiency in machines is always less than 100% due to factors like friction and air resistance.
