1. Aerodynamics

2. What is Aerodynamics?
Aerodynamics is the study of the affect of airflow on a body.
The body may be anything that moves through air or has air moving past it.

3. What is Aerodynamic Drag?
When an object is moving through the air, its motion is resisted by air flow. This resistance is called drag.

4. How is Aerodynamic Efficiency Measured?
An object’s aerodynamic efficiency, or how easily it moves through the air, is determined using a unit of measure called coefficient of drag, or Cd.
This Cd is multiplied by the frontal area of the object to figure out aerodynamic efficiency. The smaller the frontal area, the more aerodynamic the object can be.

5. Testing Aerodynamic Efficiency
Technicians measure how aerodynamically efficient an object is by testing it in a Wind Tunnel.

6. What Are The Effects of Drag?
The amount of drag determines the maximum possible speed.
It determines the fuel efficiency of the vehicle.
It determines how well the vehicle will handle.

7. Car Bodies The purpose of a car body is to do three things:
Provide protection from the elements, impact and debris.
Fuel efficiency and handling through aerodynamics.
