having a shape that helps an object move quickly through air. You use this to describe things like fast cars or planes that are built to reduce wind resistance.

For teachers: relating to the properties of moving air and the interaction between the air and solid bodies moving through it. Often describes shapes designed to minimize drag and maximize efficiency.

## Examples

- The new sports car has a very aerodynamic shape.
- Engineers designed the bicycle helmet to be more aerodynamic, helping the racer shave seconds off her time.
