World Pendulum @ e-lab

World Pendulum is a project with the main purpose of studying the behavior of standard gravity with latitude. Several automated simple pendulums are distributed across different latitudes. Each of these pendulums can be remotely operated over the Internet, communicating in real time the measured period of the oscillations, which may then be used to calculate the value of g. This article describes the World Pendulum project and it´s implementation integrated into e-lab, a software framework that allows remote control of real experiments over the Internet[1]. Preliminary results show that a good agreement with the established spherical harmonics model is obtained, with the absolute overall error being under 0.0002 m/s².
