Homework Help: Velocity squared vs position graph

  1. Sep 5, 2008 #1
    I calculated a slope from a best fit line of a velocity squared vs position graph but I don't understand what this slope represents. My units come out to be in cm/seconds squared, so does that mean thats my acceleration? It seems to be way off from 9.80m/sec^2 which should be my acceleration. Or does this slope help me determine to acceleration?

    Well from [itex]v^2=u^2+2as[/itex]

    If you plot v2 vs. s, your gradient should be 2a

    Isn't that only if the graph was velocity squared vs time? Because s is seconds right?

    s is displacement.

    t is usually used to inidicate time.
