Very small question!

  1. Sep 14, 2010 #1
    1. The problem statement, all variables and given/known data


    http://www.worsleyschool.net/science/files/average/graph1b.gif


    Is the acceleration zero for this entire velocity graph?


    2. Relevant equations

    v = delta x/ delta t
    a= delta v/ delta t


    3. The attempt at a solution

    If i were to convert this velocity graph to an acceleration graph, i think it would be a straight line on the t-axis.

    yes, the velocity is constant all the time, it just changes instantaneously at t=3 and at t=6. If there were non-zero acceleration the velocity would change over time and you would see a slope (upwards or downwards) in a velocity versus time graph.

    thank you very much for the reply,

    but just to make sure: so the acceleration graph of this velocity graph would be just a straight line on the t-axis ( 0 acceleration) ?

    yes that's correct
