what is aerodynamics
What is aerodynamics?
  • The word comes from two Greek words:
  • aerios concerning the air
  • dynamis meaning powerful.
definition
Definition
  • Aerodynamics is the study of forces and the resulting motion of objects through the air.
forces of aerodynamics
Forces of aerodynamics
  • Frictionis the force of resistance that occurs when movement takes place between any two objects or substances that make contact

object direction

force of friction

Drag
  • Force acting on an object in motion through a fluid (in this case air) in an opposite direction to the objects motion, produced by friction.
lift or downforce
Lift (or downforce)
  • Downforce is the same as the lift experienced by airplane wings, only it acts to press down, instead of lifting up.
what are some things you can do to increase the aerodynamics of your co 2 car
What are some things you can do to increase the aerodynamics of your CO2 car?
  • shape
  • weight (lighter is not always better)
  • sanding, painting
  • precision (take your time, measure twice and cut once)
