摘要
The use of multiple photos, available in most popular digital cameras, is used here in the organization of a learning situation in kinematics. This work focuses the didactic transposition that could make a significant learning, achieved through the involvement of students in the collection, manipulation and interpretation of data, besides the re-signification given to objects of everyday life. The motion of a car is studied, on the basis on data taken directly from the speedometer. The direct measurement of distance is compared with that obtained from the area in a graphic v vs. t. Uncertainties of measurements are discussed on the basis of current traffic laws.
