Friction is defined as the resistance to movement.

Air is a viscous fluid.

A car with a Cd of 1.0 is more aerodynamically efficient than a car with a Cd of .10.

If the speed of a vehicle is doubled, drag will also double.

The best techniques to use to reduce friction in a moving vehicle are to use axle bearings, lubricate and polish moving parts, and make sure axles are straight.

A ramp test accuracy of 80 is better than a ramp test accuracy of 90.

Unbalanced wheels can cause energy to be wasted.

The eye screws on the bottom of a CO2 car are an example of a suspension system.

The plastic wheels on a CO2 car are an example of a support system.

The study of airflow and the forces involved when an object moves through the air is

The force acting on a moving vehicle that counteracts (is opposite of) thrust is

Of the following, the one with the largest coefficient of drag is the

When the boundary layers surrounding a vehicle begin to build on top of one another creating drag, this type of drag is called

Drag caused by irregularities or protrusions on outer surfaces of a vehicle is called

Shapes that permit air movement with the least amount of drag are called
