Homework Help: How do I calculate speed in a velocity-time graph? Displacement-time graph?

  1. Feb 17, 2009 #1
    1. The problem statement, all variables and given/known data
    How do I calculate speed in a velocity-time graph? And in a displacement-time graph?

    2. Relevant equations

    3. The attempt at a solution
    I'm quite at a lost at how to calculate these =S
    Any help is appreciated.

    If your graph is V(t) vs. t then isn't the graph at any point the V at that particular t?

    For displacement and time, what is the definition of speed? Change in displacement for a change in time? And if you examine an extremely small time change at a point then what is that?
