Homework Help: Free fall?

  1. Sep 8, 2010 #1
    1. The problem statement, all variables and given/known data

    The question asks me to explain why the graphs should be a straight line?
    We had to make a Distance vs Time^2 graphs.




    3. The attempt at a solution

    On a position x time graph If the ball is falling only way it can be a straight line if the velocity is constant , right?

    I don't have an electronic copy of the graphs on me but here is how the professor answered it.

    That is correct, you get a curve (what shape?) when plotting position vs. time for an object accelerating with constant acceleration. But this problem asks you to plot distance on the y axis vs. t^2 on the x axis.
