The principle of the pendulum was discovered by Italian physicist and astronomer Galileo who set out that the period for the back-and-forth oscillation of a pendulum of a given length remains the same,no matter how large its arc,or amplitude.This phenomenon is called isochronism,and Galileo noted its possible applications in timekeeping.Because of the role played by gravity,however,the period of a pendulum is related to geographical location,because the strength of gravity varies as a function of latitude and elevation.For example,the period will be greater on a mountain than at sea level.Thus,the pendulum can be used to determine accurately the local acceleration of gravity.
