Homework Help: Ugh i suck at this and need your help

  1. May 25, 2003 #1
    I am doing a lab on finding g using a simple pendulum experiment.

    the formula is:

    T = 2pi sqrt(L/g)

    how is that rearranged to find g?

    I got g^2=2piL / T

    is that right? thanks

    g = ((L)/((T)/(2pi))^2)

    You forgot to square the 2*pi

    Just do the same things on each side.

    e.g. if a = 1/b, then multiplying on both sides by b gives

    ab = b/b = 1

    ab = 1.

    Similar for multiplication and to invert square root, simply square both sides.
