Question

Imagine that two people of equal weights climbed the same flight of stairs. One runs and the other walks.Do they burn the same amount of calories? Explain

Answer 1

Take into account that the amount of calories burnt comes from the work done by the two peoples when the clim the stairs.

Now, consider that the work done by the two people is the same, because ir depends on the force required to clim the stairs and the distance of the application of the force. It means that work done (an so the calories burnt) does not depend on the speed of the person.

Hence, you can conclude that the two peoples burn the same amount of calories.
