Finally, launch the acquisition and release mass m.

3.3 Results and interpretation
Applying Newton's second law on the car and ignoring friction of car on the bench. We
have acceleration:
Right-click on the graph then click on "Droite", place line on top of area which the
acceleration is "constant" (figure 11). We have a=-0,078, therefore ||aexp||=0,078g.
Numerical values:
ENGLISH
Put the car on the test bench, and calibrate accelerometer value to zero:
→ "Réglage" → "Régler" (figure 11)
m=16,1-gram
