What are aerodynamic forces?

Aerodynamic forces are like invisible pushes and pulls that happen when something moves through air, just like how you feel a breeze on your face when you run outside.

Imagine you're riding your bike down the street. When you pedal fast, it feels easier to move forward, that’s because the air is helping you go faster. But sometimes, like when you try to ride into the wind, it feels harder, the air is pushing back against you. These invisible pushes and pulls are what we call aerodynamic forces.

Think of your bike as a superhero flying through the sky. The air around it is like a crowd cheering or booing. When your bike moves forward, the air gets pushed aside, that’s the force helping you move. But if there's wind coming from the front, it’s like someone giving your superhero a big hug, making it harder to go forward.

These invisible pushes and pulls are what make planes fly, cars zoom down the road, and even help you ride your bike faster! They're all around us, working quietly in the background.
