Very Quick Force-Acceleration Graph Question

  1. Sep 27, 2009 #1
    1. The problem statement, all variables and given/known data

    What quantity does the slope of a force-acceleration graph represent?

    2. Relevant equations

    N = kg*m/s/s

    A=m/s/s

    3. The attempt at a solution

    Well since the slope = rise/run, and the y axis is the N and the x axis is the acceleration, the slope is therefore (kg*m/s/s)/(m/s/s) or simplified just kg.

    So the slope represents simply the mass quantity expressed in kg?

    yes that is correct.

    But wouldn't that just be the units of the slope, kg, instead of what the slope actually means? Would the slope mean the mass of the object ... i am totally confused

    the slope gives the mass of the object. The slope is the same as finding F/a . From Newton's 2nd Law, if F=ma then m=F/a
