Work done by friction/gravity

  1. Oct 31, 2012 #1
    1. The problem statement, all variables and given/known data

    In a lab experiment, we pushed a cart up an inclined plane. The cart had wheels and we are taking friction into account. I'm told to describe both qualitatively and quantitatively the work done by force of gravity on way up track and then once again for back down. I also have to compare this with the force of friction.

    2. Relevant equations
    Work by gravity = -Ugravity = -Fd


    3. The attempt at a solution
    I'm just having trouble putting this into words. Can anyone help?
