Aerodynamics is the study of the dynamic motion of air as it meets an object. The field is related to gas dynamics and fluid dynamics.Infocell: Gas Dynamics in Areotechnology Fluid Dynamics Inc.: Definition of Fluid Dynamics Analyzing the flow of air around an object enables the accurate calculation of forces acting upon it. Calculations include pressure, temperature, velocity and density.NASA: Beginners Gide to Areodynamics This allows the development of equations for momentum, energy and conservation of mass. The use of aerodynamics permits scientific experimentation of heavier than air flight.

Sound Barrier
The sound barrier is the point at which an aircraft changes from transonic to supersonic speed. The term originates from World War II when pilots began to experience a range of aerodynamic effects including compressibility. In the 1950s more planes began to break the sound barrier on a regular basis. -
