Homework Help: Uncertainty for measurement

  1. Jan 11, 2012 #1
    I want to calculate the uncertainty in the period for a spring, when I have measured the extension of it under the influence of gravity.
    Call that x and say I got:
    x=0.10m ± 0.01
    And we know that:
    T = 2∏√(x/g)
    Is it then correct to use the following formula for the uncertainty σT:
    σT = dT/dx * σx

    That would work, yep.
