Which is the best description of power? A. the amount of kinetic energy lost during motion B. a measure of how fast an object can travel
C. the amount of energy transfer during motion
D. a measure of how fast a machine performs work

D. a measure of how fast a machine performs work

Explanation:

Power can be defined as the energy required to do work per unit time.

Mathematically, it is given by the formula;

Hence, the best description of power is that, it is a measure of how fast a machine performs work.

This can be calculated by using the mathematical expression below;

But we know that,
