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.

Question

can you verify if my answers in the "calculation chart" are correct? (all final answers should include correct significant digit/decimal places/units.)

the height of one step = 170mm and the number of steps the students ran = 24 steps.

 

Purpose
The purpose of this lab is to measure the maximum power generated from six students when running up the stairs and discover which student
can generate the maximum power.
