How does Aerodynamics work?

Aerodynamics how does it effect us in our daily life?

Aerodynamics keeps us from going fast so we do certain stuff, but if we cut through the air we can go as fast as it let's us.

What do we do to keep it from holding us back as much?

We out car windows at an angle so that the car can cut through the air easier and it saves gas.
If your running a race and your leaning but the other person is standing straight up you have an advantage when you start.
on roller coasters they build it to were it can go as fast as it can through the air to make it as aerodynamic as they can.
