Homework Help Overview

The discussion revolves around estimating the amount of power generated by a person while climbing stairs, focusing on the relationship between energy expenditure and time.

Discussion Character

  • Exploratory, Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • Participants explore how to estimate power by considering energy and time. Questions arise regarding the estimation of energy involved in the process, particularly the energy from chemical reactions in the body versus gravitational potential energy.

Discussion Status

Some guidance has been offered regarding the relationship between work done against gravity and gravitational potential energy, while participants continue to question the accuracy of approximations and the nature of energy involved.

Contextual Notes

There is a mention of the difficulty in estimating real energy due to the complexities of biological processes, and assumptions are made about climbing at a constant speed.

Can anyone give me an idea on how to estimate the amoung of power that a normal person will general as he climbs stairs?

Power is energy in unit time.Estimate the time in which energy is being expended and that amount of energy.

But how about energy?

How can I estimate energy?
 
Unfortunately,u can't estimate the real energy involved,namely the energy released from the chemical reactions that take place in your body while u're climbing that ladder.But you can approximate (i don't know how accurate,though) that with the work done by your body against gravity (equivalently,the variation in gravitational potential energy of your body),assuming you climb at constant speed wrt the ground...
