Data & Results

Procedure in Constructing the Car:

1. Cut the styro and roll the papers and glue the papers to the styro.
2. Cut the illustration board the same size as your cd.
3. Insert the bbq stick in the paper rolls
4. Make a hole in the bottle caps
5. Glue the bottle caps in the cd
6. Insert the cd into the bbq sticks.
7. Put clay in the end of the sticks
8. Put rubber in the styro and paper clip
9. Glue the illustration board to the styro.

Explanation:
The first trial of our car is 0.61 m for 5.27 s. The second trial of our car is 0.92 m for 5.76 s. It went further. The third trial of our car is 0.58 m for 3.59 s. It decreased in time and distance. The fourth trial of our car is 0.71 m for 5.60 s. It went further again. The fifth trial of our car is 2.35 m for 13.44 s it went further and the time sped up. Forces acting on the car while at rest:

Conclusion and Recommendation:
How does the design of a “rubber-powered car”
