RESUMO

We have made a mechanical system that consists of a base and a vertical axis that supports a rail. In the ends of the rail two photogates have been prepared. The photogates have been designed and constructed to measure time intervals of rigid solids that move on the rail and that happen for the photogates. The prototype is of low cost and is used for practices of laboratory concerning with kinematics and dynamics of translation, and dynamics of the rigid solid in mechanics courses.
