Application: 1. Will your hp change if you performed the activity for a longer duration (for example, climbed the CN tower staircase)? In what way? Explain. 2. Research the horsepower generated by a car. How does the average person's peak power rating compare to it? How many average people would it take to generate the same horsepower as the typical car?

Are you as strong as a horse?
Purpose: To understand the concept of work and power and to calculate the power
generated by yourself or a friend.
Materials: A tape measure, stairs, and a stopwatch, cell phone, or wristwatch.
Key Physics Concept: Power is the rate of doing work. Power can be calculated by
dividing the work done by the time it takes to do the work; in this case we will do work
against gravity on a stair case (you may add your power in doing pushups to test your
arm power). Can you guess what your peak horsepower is?
You may do the stairs one at
at time or multiple stairs at a
a time; whatever is most safe
and efficient for you.
