Aerodynamics is the study of how air interacts with moving objects.
It is a branch of physics and engineering.
The word comes from “aero” meaning air, and “dynamics” meaning motion.
Aerodynamics explains how objects move through the air.
It is important for designing airplanes, cars, and rockets.

The main forces in aerodynamics are lift, drag, thrust, and weight.
Lift helps airplanes rise into the air.
Drag slows objects down due to air resistance.
Thrust pushes an object forward.
Weight is the force of gravity pulling it down.

Streamlined shapes reduce drag and help objects move faster.
Aerodynamics is also used in sports, like cycling and racing cars.
Birds and insects naturally use aerodynamics to fly efficiently.
Wind tunnels help engineers test aerodynamic designs.
Good aerodynamics improves fuel efficiency in vehicles.
It makes airplanes safer and faster.
Understanding aerodynamics is essential in modern technology.
Aerodynamics connects science, engineering, and everyday life.
