Expression for time period of simple pendulum

  1. Dec 24, 2011 #1
    Which of the two is a better expression for the time period of a simple pendulum?
    t-=2∏[itex]\sqrt{(l/g)}[/itex] or t=2∏[itex]\sqrt{(1/T/m)}[/itex] ; l=length of the pendulum
    T=time period of the pendulum
    m=mass of bob
    Note:g is not equal to T/m as there is pseudo centrifugal force such that T + centripetal force=mg

    The first one is the useful expression...
