What word describes a force that slows an object down when air pushes against it?

• drag

• drafting

• downforce

• deceleration

What does the science of aerodynamics study?

• the weight of objects

• the speed of flight of objects

• the movement of air

• the sound of air

What are three key aerodynamic rules or principles?

• drag, height, acceleration

• drag, downforce, drafting

• acceleration, downforce, motion

• acceleration, height, motion

What aerodynamics force is used to create both lift and downforce?

• air speed

• air pressure

• Both A and B

• Neither A or B

A race car is aerodynamically balanced when there is a balanced force on :

• the front and back wheels

• the spoiler and the roof

• the splitter and the rear bumper

• none of the above
