Car Aerodynamics: How to Reduce Drag | Science Project

What is the purpose of using yarn and tape in car aerodynamics experiments?

• To measure the car's speed

• To decorate the car

• To improve the car's color contrast

• To visualize airflow patterns

What happens to the yarn streamers when there is attached flow?

• They point straight along the car's body

• They change color

• They flap all over the place

• They fall off the car

Which experiment involves observing the effect of driving with windows down?

• Mounting a camera as a hood ornament

• Using vortex generators

• Adding a roof extension

• Driving with windows down

What is a potential risk when testing car modifications on public roads?

• Increasing car speed

• Changing the car's color

• Modifications flying off and hitting another car

• Improving fuel economy

What is suggested as an easier way to film the experiments?

• Using a drone

• Having a second person film from inside the car

• Filming at night

• Using a stationary camera
