Overall our car was not successful to the degree of completing the entire course solely with the force of gravity and did not travel as far as anticipated.
The highlights of our car, however, were a fully functional steering and braking system along with a frame that was able to support the weight of the driver.
In the future if we were to modify our car we make some engineering changes in our car. The biggest change that would effect our car’s performance would be increase the size of the back wheel compared to the front wheels. This increases would result in an increase in the magnitude of the force of gravity and decrease the magnitude of friction. As the radius of the back wheel increases the angle theta increases. When theta increases the magnitude of gravity (mg sin theta) increases and decreases the magnitude of friction (cmg cos theta, c= coefficient of rolling friction).
