Homework Help: Distance v.s Time graph shape?

  1. Sep 8, 2010 #1
    1. The problem statement, all variables and given/known data
    What would be the shape of Distance vs Time Graph when a ball is falling?
    Please explain. Thanks you



    3. The attempt at a solution

    I think it will be a curve since the acceleration is constant (9.8 m/s^2) . the slope under the curve will be velocity which will change uniformly overtime? It can't be a straight line since that will make the velocity constant and acceleration zero? I am not sure , need to verify :/

    It will curve upward if you plot the distance increasing on the y axis. If you plot it starting at the height from which it was dropped, it will look like the second half of the trajectory of a cannonball (where the velocity along the ground functions just like time on the x axis).
