Homework Help: Explaining Diagrams using Physic concepts

  1. Jun 15, 2010 #1
    Here I have a question which I'm unfamilar with. I'm not sure how to answer the question by explaining what is involved with the diagram.

    Discuss the following pictures in terms of work and power outlining any assumptions that you make.

    What is work and power? Does the boy do work while moving upstairs? When does he reach the top of stairs sooner? When does he exert higher power?
