Question
Which of the following correctly describes power? force measured on an ergometer multiplied by the time pedaling. work performed on the ergometer divided by the time pedaling. force measured on an ergometer divided by the time one exercises. force measured on an ergometer times the distance pedaled.
Solution
The correct description of power is "work performed on the ergometer divided by the time pedaling."
Here's why:
-
Power is defined as the rate at which work is done or energy is transferred. In other words, it is the amount of energy consumed per unit time.
-
In the context of an ergometer (a device that measures work or energy expended during a period of physical exercise), the work performed would be the force applied to the pedals multiplied by the distance pedaled.
-
Therefore, to calculate power, you would divide this work performed by the time spent pedaling.
So, the correct answer is "work performed on the ergometer divided by the time pedaling."
