The speed and flight of objects
The movement of air
The sound of air
What are three key aerodynamics principles?
Drag, height, and acceleration
Drag, downforce, and drafting
Acceleration, downforce, and motion
Acceleration, height, and motion
What word describes a force that slows an object when air pushes against it?
Drag
Downforce
Drafting
Deceleration
What aerodynamics force is used to create both lift and downforce?
Air speed
Air pressure
Both A and B
Neither A nor B
A race car is aerodynamically balanced when there is balanced force on:
The front and back wheels
The spoiler and the roof
The splitter and the rear bumper
None of the above
True or false? Downforce is the opposite of lift.
True
False
True or false? Aerodynamic balance is complicated, which makes it impossible for engineers to use it to improve a race car’s performance.
True
False
Drafting happens when:
Two or more race cars accelerate next to each other with inches between them.
Two or more race cars line up, one behind the other, with inches between them.
Two or more race cars tap the bumpers of the cars in front of them.
None of the above
The goal of adaptations to NASCAR race cars is:
To prevent race cars from flipping over or lifting.
To provide more downforce to improve tire traction.
To force high-pressure air over the car to make sure it “sticks” to the track.
To create more contact between the tires and the track.
All of the above
Why is the science of aerodynamics important to racing?
Aerodynamics helps improve the safety of the race cars, keeping them on the track.
Aerodynamics enhances the speed of the race cars, helping drivers zoom past the competition.
Aerodynamics helps improve the performance of the cars, keeping them running smoothly and consistently.
All of the above
