As a pendulum can be used to calculate the gravitational field strength by using the equation(adsbygoogle = window.adsbygoogle || []).push({});

Time period= 2(pi) sqrt (length/g)

this equation assumes that the pendulum bob is moving in Simple harmonic motion. However at very small lengths the pendulum bob tends to move in a more circular motion will this at all effect the time period and hense my value for g?

hopefully that makes sense =]

cheers
