Homework Help: Velocity Time Graph Clarification and Insight Please

  1. Sep 3, 2009 #1
    1. The problem statement, all variables and given/known data

    What type of motion is occuring when the slope is changing and the graph is therefore curved on a velocity time graph?

    2. Relevant equations


    A= (delta)v/(delta)t

    3. The attempt at a solution

    my thought is that when the slope is changing the acceleration is either increasing or decreasing ...

    So if I were to have an upward sloping curved v-t graph, this would mean that the average acceleration is increasing with time, while if i were to have a downward sloping v-t graph the average acceleration would be decreasing with time...

    and if i had a line (linear) slope on a v-t graph, we would have uniform acceleration...

    Yep. The slope of a velocity-time graph is acceleration. So if the function is linear ie slope is constant, then acceleration is constant. It the slope isn't constant you have a changing acceleration.
