Uniform linear motion with the 2-1 timer

Product No: P1003505

Principle

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 them.

Task

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 time.

Express in grafic form the principles which have been established.

Speed is measured by determining the distance and time associated with a motion.
