Homework Help: Net force vs position

  1. Sep 23, 2007 #1
    1. The problem statement, all variables and given/known data

    A small box is moved from position x1 to x2 by a net force which varies with position. On a graph, I plot the net force on the box vs. its position. The area in between the force curve and the x axis is ................... And I am not sure if it is the work done on the box or may be something else

    2. Relevant equations

    3. The attempt at a solution

    The area enclosed by the curve and x-axis is indeed the net work done by the force. The formal definition of work;
    [tex]\int^{x_1}_{x_0}f(x) dx[/tex]
