Experimental pedagogical approach: Foucault's Pendulum

The objective of this paper of explaining in a simple way, the rotation of the earth from the relative trajectories of Foucault's pendulum on a rotating turntable, a pedagogical approach based on the history of science. University students with the opportunity to achieve and improve the understanding of the rotation helped plan cycle in which the pendulum oscillates in a rotating frame without external intervention, can only be explained because the earth insists on turning on itself, and for several billion years, en particular the existence of the effect of inertia forces. On the other hand a digital camera Sony 10 Megapixel Cybers hot shooting to take snapshots of the swinging pendulum has been used, is to transform the video taken by the camera in kinematic trajectory. This is possible using suitable software such as Latis-Pro, etc ... avemica. We opted Latis-Pro, more user-friendly, feature-rich processing and compatible with Excel, simulates the relative motion of the pendulum.
