Aerodynamics is a branch of dynamics concerned with studying the motion of air, particularly when it interacts with a moving object.

Aerodynamics is a subfield of fluid dynamics and gas dynamics, with much theory shared between them. Aerodynamics is often used synonymously with gas dynamics, with the difference being that gas dynamics applies to all gases.

Understanding the motion of air (often called a flow field) around an object enables the calculation of forces and moments acting on the object.

Typical properties calculated for a flow field include velocity, pressure, density and temperature as a function of position and time.
