Atwood's Machine Question

  1. Nov 1, 2009 #1
    1. The problem statement, all variables and given/known data
    What is the relationship between the total mass and the acceleration of an Atwood’s machine?

    3. The attempt at a solution
    I have a graph from the lab, but the regression value for the best fit line is very poor, so it is difficult to tell much from the values. I can see that as the total mass increases the acceleration goes down, but I don't know how to explain this. I don't even know what sort of graph the best-fit line would have (straight or parabola). I would appreciate any help.
