Spring constant and uncertainty in spring constant calculation

  1. Oct 20, 2008 #1
    1. The problem statement, all variables and given/known data

    The spring constant (k) and uncertainty in the spring constant(sigma_k) have to be calculated with the values available for: period (T), number of oscillations (N), mass (m), time, slope and uncertainty in slope. The spring constant can be done with the first equation but I have no idea how to calculate the uncertainty in the spring constant.

    2. Relevant equations

    [k+/- (sigma_k)] = [4(pi)^2]/[slope +/- (sigma_k)]

    3. The attempt at a solution

    The only uncertainty you have in k - given your formula - is the uncertainty in the slope.
    There is no uncertainty in the constants like π, so you use the percentage uncertainty of the slope as the percentage uncertainty of k.
