Abstract:
|
Elementary formulas for gravitational potential energy, heat capacity, and Newton’s law of cooling can be used to measure and compare the efficiencies of a person traveling uphill and downhill. Good agreement is found for their ratio with more sophisticated experiments in the literature made by measuring respiration to determine metabolic power. A simple argument explains why human muscles are less than 50% efficient at converting chemical into mechanical energy.
