Aerodynamics (shaping of objects that affect the flow of air, liquid or gas) is a branch of fluid dynamics concerned with the study of forces and gas flows.

The solution of an aerodynamic problem normally involves calculating for various properties of the flow, such as velocity, pressure, density, and temperature, as a function of space and time.

Understanding the flow pattern makes it possible to calculate or approximate the forces and moments acting on bodies in the flow.

This mathematical analysis and empirical approximation form the scientific basis for heavier-than-air flight..
