Objectives/Goals

Objective: The objective of my project is to determine which model car will travel the furthest when released from a ramp, based on its aerodynamic design. My hypothesis was that the teardrop shaped car, due to its highly streamlined design, would be the most aerodynamic model and travel the furthest.

Methods/Materials

Materials and Methods: Four Styrofoam blocks, all the same size, were cut and shaped into four different body styles: a block (the control), a wedge, a standard sedan, and a futuristic teardrop designed car.

Each model was weighed on a postal scale and washers added to the lighter models in order for them to weigh the same.They were then sent down a ramp, ten times each. Their distances were then charted.

Results

Results: The wedge car went further on average than the other models, while the unshaped block traveled the shortest average distance.

Conclusions/Discussion

Conclusion: My conclusion is that aerodynamics is an important factor in the distance a model car can travel and that compromises between downforce and drag must be met to design an efficient chassis. 3rd party site
