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.
