Question: Which of the following explains the relationship between work and power when running or walking up a flight of stairs? A. Running requires the same amount of power, but more work than walking. B. Running requires the same amount of work, but more power than walking. C. Running requires more work and more power than walking. D. Running requires less work and less power than walking.
B. Running requires the same amount of work, but more power than walking. Explanation: Whether you're running or walking up a flight of stairs, the amount of work remains the same because work is defined as force times distance. However, because power is the rate of doing work or the amount of work done per unit time, more power is required when running up the stairs because this is done in a shorter amount of time compared to walking.
