Intro: We made this lab to determine why
John crashed his car. We had to decide whether or not it was actually his
fault.
Materials: Toy Car, Ruler, Stopwatch, and Water
Results: We found out that the water on the
road ,because of the light rain, reduced traction, made the car go faster, and
slide. We also found out that tires need good traction to stop
better.
Hypothesis- The lack of traction on the car
caused it to slide and go faster.
Our tests proved the hypothesis because
because the speed of the car without traction on water was faster than with
traction.
Conclusion: Cars need good traction to
drive well, brake and turn on the wet or dry road.
