Simple pendulum amplitude

  1. Oct 28, 2011 #1
    How to calculate g if amplitude of a simple pendulum is negligible and the length is known?




    T=2π[itex]\sqrt{}l/g[/itex]

    In terms of the period? Just solve for g in terms of T and L.

    No, only in terms of L.

    Check your problem:
    Why should the length L depend on the strength of gravity? This is usually something you just cut to whatever length you like - 1m on Jupiter is the same as 1m on the moon... unless, I suppose, you are doing the measuring from a different gravity from the one the meter is in? (This forum I don't want to make too many assumptions!)
