Homework Help: Pendulum Graphs

  1. Nov 8, 2011 #1
    1. The problem statement, all variables and given/known data

    Using the slope from a graph of the square root of the pendulum's length vs period (which would be a linear relationship), calculate the experimental acceleration due to gravity.

    2. Relevant equations

    I'm trying to figure out what equation I can use to solve for 'g'.

    I know that T = 2*pi*√(L/g), but will that help here? I need to use the slope of the graph in order to calculate g.

    Thanks in advance!

    Use the fact that √ (a/b) = √a/√b and get your equation in the form Y = MX so that the gradient is M.
