I answered the questions(not sure if they are right) but I would like to know the best way to explain these questions on a test/quiz.
1) Describe the transfer of energy that enables a person to climb stairs.
I put: The person's body first uses the chemical energy from food/water as potential energy. It is then converted into kinetic energy in the form of the action of climbing stairs.
2)How is energy expenditure and potential of the person at the top of the stairs related?
I put: Energy is spent in form of kinetic energy by climbing stairs, equals the gravitational potential energy at the top of the stairs.
3) What would be the most important physical characteristics required for maximum power.
Not sure what I would put for this one :O
Thanks
