What could T^2 be? Pendulum lab

  1. Oct 9, 2012 #1
    1. The problem statement, all variables and given/known data
    I did a physics lab in high school the other week, and I did not look at the rubric for the lab report until now. The lab's purpose was to find the correlation between mass and swing periods, and length and swing periods. The rubric asks to graph T vs. m, T vs. L, and T^2 vs. L. I'm do not know for sure sure what T^2 could stand for.

    Angle of release: 20
    Sphere mass(kg) Total time for 10 swings (s)
    cork .003 9
    wood .006 10
    aluminum .0024 9
    steel .067 11
    brass .072 11
    lead .094 11

    Sphere: Steel
    Angle of release: 20
    Length total time for 10 swings (s)
    0.2 10.57
    0.3 9.73
    0.4 10.21
    0.5 9.73
    0.6 11.53
    0.7 10.81
    0.8 10.47
    0.9 16.46
    1.0 15.65
    2.0 16.35
    3.0 17.08
    4.0 18.35


    2. Relevant equations
    None.


    3. The attempt at a solution
    Could actually be time squared, or it might mean time to graph in 10 seconds compared to 1.

    T^2 = T*T

    so time squared.
