Fluid Mechanics - The study of movement through air and water
Air Resistance - The force that opposes the direction of motion travelling at high velocity through the air
Drag - The force that opposes the direction of motion through water
Frontal Cross sectional Area
Track cycling and Skiing are largely affected due to the large frontal cross-sectional area facing the oncoming air
The larger the frontal cross sectional area the larger the air resistance or drag
Streamlining and Shape
The more streamlined or aerodynamic the body in motion the lower the air resistance or drag
Streamlining is the creation of smooth air flow around an aerodynamic shape
Many sports use a tear drop or aerofoil shape for helmets Eg Cyclists
Surface Characteristics
Eg clothing (Lycra)
The smoother the surface the lower the air resistance or drag
Increasing Friction
Football and Rugby Boots
Chalk on bars (Gymnastics)
Grips of Bats and Rackets
Decreasing Friction
Swimming Caps
F1 Tyres
Waxing Ski's
