Human Power Lab

  1. Purpose – The purpose of this experiment is to determine your horsepower.
  2. Materials and Methods
    1. Use scale or knowledge of your weight to determine your mass in kg.
    2. Measure the height of one step.
    3. Count the number of steps you will climb up.
    4. Start at the first stair and have your partner time you as you run as fast as possible up to the top of the bleachers.
    5. Repeat 3 times.
    6. Calculate your power.
    7. Calculate your horsepower using the conversion in your book cover.
    8. Calculate your horsepower per body mass.
    9. Record the classes horsepower and horsepower per body mass in a data table.

IV. Conclusion: Which value is more consistent in the class data? Why? If we recorded work for everyone, how would the values compare? Why? What type of person has the most horsepower per mass (small, fast, etc.)
