Dragster Engineering Concepts
Vocabulary
• Dragster: Two specially designed cars, that race side by side, down a ¼ mile track

Vocabulary
• Aerodynamics: The ability of air to move freely above, around, and beneath a moving object.
• Better the aerodynamics=faster the object will move
Good Aerodynamics
Poor Aerodynamics
Vocabulary
• Lubricants: Substance that is used to reduce friction which causes moving parts to move faster
Vocabulary
• Turbulence: Swirling around of air molecules
What does Turbulence feel like?
Vocabulary
• Contact Area: The total area that a dragster comes into contact with the wind
Vocabulary
• Force: The energy needed to move something
Vocabulary
• Friction: Is a force that holds back the movement of a sliding object
Vocabulary
• Mass: The space that an object occupies
Is the cloud heavy or massive?
Vocabulary
• Frontal Area: The front part of the car that comes into contact with the air. Keep it small!
Vocabulary
• Boat tailing: As air moves past a curved object, it creates a pinching effect which pushes the dragster forward.
Vocabulary
• Surface Effect: Rougher the surface, the slower your dragster will go due to turbulence.
Vocabulary• Wheelbase: The distance of the front axel to
rear axel. Greater the distance the less turbulence your dragster will experience
