4-A third student repeats the experiment changing the two marks.
5-Exchange tools with your colleagues and repeat the experiment.

6-Write the results in a table.
7-In each time, calculate the speed of the car from the relation: V= d/t.
The following table illustrates some readings that a group of students made:

Trials Distance (d) Time (t) Speed (v) =d/t
1 0.4 5 0.08
2 0.6 7.5 0.08
3 0.8 10 0.08

4 1.0 12.5 o.08

*From this graph you can conclude: - The distance is directly
proportional to the time at

uniform speed.

- The relation between the
distance and the time at
uniform speed is
represented by a straight
line passing through the
origin point.
