Abstract

In this work is presented a discussion about the Galileo’s inclined plane showing aspects from its evolution and scientific development together with a didactical proposal to teaching move concepts from learning sciences. After an introduction of physicalmathematics concepts, it is showing the construction of an experimental aparatus with Mindstorms NXT LEGO© pieces and light sensors to measure time steps in mechanical experiments. The experiment consists of measuring the time of rolling a ball along a plane with different degrees of inclination. The getting and analysis of space and time data allow an assessment of the movement. The experimental setup allows a direct comparison between Newtonian mechanics considering the existence of a pure rolling (without sliding) showing the friction force as a precursor of the rotation of the sphere with the equation of uniform motion (without bearing). The comparison suggests that there is no pure rolling. Taking into account the easy handling of the equipment involved and the method used, it is believed that he can help spread the use of technology in teaching Physics.
