The pupils should develop the notion of linear uniform motion
experimentally, by deriving the speed of the powered car from the
measurement of the distance and time. The experiment should be
carried out with different distances and car speeds.
From the measurement values obtained the pupils should recognize
that the speed within the distances measured in these experiments
is constant and that therefore the term "uniform" applies to
What does the term "speed" mean?
Motion means that a body changes position in space. This change
requires a certain amount of time. A position is determined by the
indication of distances or lengths.
Measure the time which a car needs to cover a given distance if
it moves evenly.
Let the car move faster and determine again the distance and the
Express in grafic form the principles which have been
Speed is measured by determining the distance and time
associated with a motion.
