Presentation transcript:

A rock climber takes an abnormally long time to elevate her body up a few meters along the side of a cliff. On the other hand, a trail hiker (who selects the easier path up the mountain) can elevate her body a few meters in a short amount of time. Assuming that each of them exerts the same amount of force to reach the same final height, who has the most power? The two people might do the same amount of work, yet the hiker does the work in considerably less time than the rock climber. The hiker has a greater power rating than the rock climber.
