How do we calculate slope of a acceleration vs.time graph?

  1. Feb 15, 2010 #1
    Im doing a lab about acceleration due to gravity.
    And one of the things we had to do is make a a-t graph using the Aave and Ttotal.
    Interval ∆t Ttotal ∆d Dtotal Vave ∆v Aave(cm/s^2)
    1 0.050 0.050 2.0 2.0 40 - -
    2 0.050 .100 4.0 6.0 80 40 800
    3 0.050 .150 6.8 12.8 136 56 1120
    4 0.050 .200 8.5 21.3 170 34 680
    5 0.050 .250 11.0 32.3 220 50 1000
    6 0.050 .300 13.9 46.2 278 58 1160
    7 .050 .350 15.5 61.7 310 32 640
    8 .050 .400 17.4 79.1 348 38 760

    my graph looks something like this [PLAIN]http://www.kwantlen.bc.ca/...xtgraphquiz/images/image002[/PLAIN] [Broken].

    My question is how do we calculate slope on a a-t graph and what does this slope tell us about falling objects. Thanks

    How about this: http://img370.imageshack.us/img370/9488/96191446sb5.jpg [Broken]
    It looks similar to it
