Procedure : 1. Measure the mass of each physics student, in kilograms. Set up a suitable table in your notebook and start recording your data. 2. Measure the height of one step. Count the number of steps and multiply by the step height to determine the vertical height the student will rise, in metres. 3. With the stopwatch, measure the time the student takes to run up the stairs, in seconds, from a standing start. 4. Calculate the force of gravity on each student, using F=mg. Use this value of force in your work calculation. 5. Calculate the power developed in Watts.
