Answer 1

Answer:

Power—the word conjures up many images: a professional football player muscling aside his opponent, a dragster roaring away from the starting line, a volcano blowing its lava into the atmosphere, or a rocket blasting off, as in Figure 1.

These images of power have in common the rapid performance of work, consistent with the scientific definition of power (P) as the rate at which work is done.
