What is aerodynamic?

Aerodynamic means something moves smoothly through air, just like how you glide on a slippery slide.

Imagine you're riding your bike down a hill. If the wind pushes against you and makes it hard to go fast, that’s not very aerodynamic. But if you bend forward and tuck in your arms, the wind flows around you more easily, that's when you become more aerodynamic, like a superhero zooming through the sky.

Think about a feather falling slowly to the ground, it’s not aerodynamic. But if you drop a rock, it falls faster because less air gets in the way. That's how aerodynamic shapes work: they let things move through air with less pushback.

Cars and planes are made aerodynamic so they can go fast without using too much energy. Like when you wear a tight suit to run faster, it helps you cut through the air, just like a car or plane!
