Uniform circular motion radius

  1. Feb 28, 2008 #1
    In uniform circular motion, how is frequency proportional to:
    tension force???

    We did a lab where we connected rubber stoppers on one side of the string and masses to the other and spun it overhead and measured time taken for 10 cycles.
    I came up with:
    frequency is proportional to 1/(root(radius))
    frequency is proportional to 1/(root(mass))
    frequency is proportional to root(tension force)
    from graphing... but i'm not sure if these are right...

    I have to combine the three proportionality statements to get this equation:
    sumF = 4pi^2mrf^2

    Please help me~~~ T.T
