Measurement of Gravity (Simple Harmonic Motion)

  1. Apr 7, 2009 #1
    1. The problem statement, all variables and given/known data

    If the slope of your gradient turns out to be 4.041 s^2.m^-1 then what value would you obtain for g? State your answer in m.s^2 and to 3 significant figures.

    2. Relevant equations

    T^2 = (4 pi^2 e1 / g) - (4 pi^2 e0 / g)

    This is the one I'm supposed to use. Other ones given are...

    T^2 = (4 pi^2 e) / g

    e = e1 - e0

    3. The attempt at a solution

    I have no idea what I'm supposed to be doing. Graph is T^2 vs. e1
    I did, however, look on the internet. There is alot of stuff about a spring constant, but thats not mentioned anywhere on my sheet. Values are different and I can't get my head around it properly.

    Thanks for your help =)

    The gradient m is supposed to be T^2/e1.
    Now g = 4*pi^2*e/T^2 = 4*pi^2/m
