If you plot the distance d as an ordinate (y-axis) versus the time of fall t as an abscissa (x-axis), do you expect to get a straight line? What type of curve do you expect to get?

Since a straight line on a distance time graph implies uniform speed, and falling is an acceleration - a non uniform speed - I woul not expect a straight line. I would expect to get a parabola. This is based on the kinematic equation s=ut + (1/2) at^2. If something is dropped from rest, u = 0; so s = (1/2) at^2Which is, I think, the equation of a parabola.
