Homework Help: Which of the following things DOESN'T change if you double this?

  1. Dec 1, 2012 #1

    Why is the answer to this period?

    I know

    T = 2π√(L/g)

    But I don't know how period doesn't change if you double amplitude, when amplitude isn't even in the equation (?)

    Perhaps the fact that amplitude is not in this formula for period means that the period does not depend upon the amplitude.
