Calculate Your Horsepower
Calculate Your Horsepower
OBJECTIVE:
To calculate the horsepower that you develop as you walk, jog, or run up a flight of stairs. This is only an approximate value. Explain why in the conclusion.
THEORY:
Power equals work divided by time. One horsepower (HP) equals 550 ft•Ibs/sec.
P = W/t = Fd/t = F(d/t) = Fv
APPARATUS:
Stopwatch, sneakers, meter stick.
PROCEDURE:
1. Measure the vertical distance between floors. You will also need to record your weight.
2. Walk up the stairs as if you were headed for class (slowly). Repeat this several times. Average these times.
3. Ascend the stairs at a trot. Again, repeat and average these times.
4. Ascend the stairs as fast as you possibly can. Repeat and average these times.

Analysis:
1. Calculate your horsepower from your three different average times. Show all your work in the space below.
2. Calculate the work done in climbing the stairs. Show all your work in the space below.
3. Did your calculation for work vary from walking to trotting to running? Explain.
4. Explain what the relationship is between horsepower and the rate (timeframe) at which the work gets done. You need to refer to your data to support your answer to this question (What trends exist?).
5. What are the sources of error in this experiment?
Conclusions: (Discuss the trends that exist in your data, and make sure you explain why your horsepower calculation is only an approximation.)
