A simple definition of aerodynamics is the study of the flow of air around and
through a vehicle, primarily if it is in motion. To understand this flow, you can visualize a
car moving through the air. As we all know, it takes some energy to move the car through
the air, and this energy is used to overcome a force called Drag.
Drag, in vehicle aerodynamics, is comprised primarily of two forces. Frontal pressure and
rear vaccum.
