The aim of this paper is to present a study on a difficult concept for students to understand the concept of inertia forces. We are focused of directed an experimental bench pedagogical nature to facilitate and improve the understanding of students, especially students 'preparatory class and first university year' of confronting the theoretical simulation model with Maple experience, and acquire technological and methodological competency. On the other hand and observed to analyze the extreme sensitivity of the trajectories relative to a rotating frame without external intervention, the initial conditions of launch of the ball and the intensity of the rotational speed and position of the plate initial vector launch, the relativity of motion and in particular the study of inertial forces on a rotating turntable. Using a digital camera, the videos are processed by a pointing Latis-pro software.
