Car Science

Mrs. Stanek's car traveled 300 inches in 5 seconds. What was her car's speed?

• 60 in/s

• 70 in/s

• 80 in/s

• 90 in/s

What effect did adding weights have on the performance of most of the cars that were UNBALANCED?

• There was no effect.

• It made the car travel a farther distance.

• It made the car travel a longer distance

• The cars spun out, did a wheely, or a stoppy.

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

Aerodynamic balance is complicated, which makes it impossible for engineers to use it to improve a race car's performance.

• true

• false

What is the primary purpose of a car's spoiler in terms of aerodynamics?

• To increase the car's speed by reducing drag

• To provide downforce and improve traction

• To enhance the car's aesthetic appeal

• To reduce the car's weight
