Abstract:

The Physics more than no other science, offers the possibility of demonstrating their principles with simple and direct experiences that allow to catch the attention of the pupil making the educational act the most attractive.
These small experiments can be carry out in the classroom allow us to visualize slightly obvious concepts or that need specify certain degree of abstraction. An example of the above mentioned, constitutes, the topic related to the relative movement widely indexed in texts of university Physics.
It is known well that the problems of kinematics of the systems of points are necessary the knowledge what a mobile observer "sees" to obtain the solution. Nevertheless, not always it is obvious for the pupil the kinematics for the mobile observer, fundamentally if this one is animated by a movement of rotation.
In this work we have designed and constructed a device that allows us to incorporate new audio-visual applicable technologies in the classroom to show of qualitative form the different path and cinematic variables of a body in movement that there measures a fixed observer and a mobile observer.
