I need help answering these questions. They are generalized and do not need data to answer them. I just need the answers explain to better understand physics.

Questions: 1. Is there a difference in your work done while walking or running up a flight of stairs? Why or why not? 2. Is there a difference in the power exerted while walking or running up a flight of stairs? Why or why not? 3. How is it possible that a student might have the fastest time up the stairs and still not have the most power? 4. If you carried a kid up the flight of stairs in the same amount of time that it takes you to go up alone, was your horsepower higher or lower? Explain. Conclusion: Write a conclusion that addresses the objectives. Indicate lessons learned, possible sources or error, and suggestions to improve the results
