Homework Help: Period T and length

  1. Nov 13, 2006 #1
    Using Newton’s laws, we could show that for some pendulums, the period T is related to the length and free-fall acceleration g by

    T=2pi(sqrt l/g)

    Can the term in parentheses be treated as a constant of proportionality?

    No, because g is always the same, and l varies depending on the pendulum

    mathematics, two quantities are called proportional if they vary in such a way that one of the quantities is a constant multiple of the other, or equivalently if they have a constant ratio.

    I have graphs of T vs. A, T vs L, T vs m

    m=bob mass

    It's a pendelum experiment
    I have graphs but how would i explain it in the graph
