Is there a difference in your work done while walking or running up a flight of stairs? Why or why not? The difference in work between walking and running up a flight of stairs comes from the time taken to complete the objective. Both activities require the same work to overcome gravitational force, running achieves this in less time compared to walking. This shorter duration of exertion during running results in less total work done, despite a higher power output due to my quicker pace. Although running expends more power per unit time, the total work done may be lower than when walking due to the faster pace. 2. Is there a difference in the power exerted while walking or running up a flight of stairs? Why or why not? When comparing walking and running upstairs, there’s a difference in the power exerted. Power is how fast you can do work, and it depends on how quickly you finish the task. While both walking and running need the same amount of effort to J. Regalado 10/26/23 Page 2 of 4
