Aerodynamics Science Fair Project

Wind Resistance and Automobile Shapes

Wind Resistance and Automobile Shapes | Science Fair Projects | STEM Projects
Wind resistance is a force that opposes the movement of an object through the air. In this project, you will explore how the shape of a car affects the amount of wind resistance it experiences.


The hypothesis is that cars with low profile, streamlined shapes will experience a lower amount of wind resistance.

Method & Materials

You will carve three shapes from polyfoam, measure the wind resistance on each shape using a Newton spring balance, and observe the results.
You will need 3 pieces of polyfoam, a paper knife, a Newton spring balance, an industrial fan, a table with a smooth surface, and a nail.


The results showed that the foam cut out with a low profile streamlined shape had the least wind resistance, while the cuboid-shaped foam had the most wind resistance. This proves that the hypothesis is true.

Why do this project?

This science project is interesting because it explores how the shape of a car affects the amount of wind resistance it experiences, which is an important factor for vehicle manufacturers to consider when designing a vehicle.

Also Consider

Consider repeating the experiment with different shapes, or with different wind speeds. Also, explore the results for water resistance.
