Bernoulli Principle - The faster fluids flow the less pressure they exert. The slower fluids flow the more pressure they exert

Aerofoil - A streamlined structure with at least one curved surface

Symmetrical - Discus and Javelin

Asymmetrical - Ski Jump and F1 Car

Angle of Attack - The angle at which a projectile is tilted or presented to the air.

Optimum Angle of Attack - 17 Degrees

Symmetrical (Aerofoil)

Above the curved upper surface a low pressure zone is created (Air travels further and faster)

As velocity increases pressure decreases

Fluids move from an area of high to low pressure which create the additional lift force

Below the flat underneath surface a high pressure zone is created (Air travels less far and slower)

Asymmetrical (Reverse Aerofoil)

An aerofoil positioned with its curved upper surface facing downwards and its flatter surface facing upwards causes downforce.

As velocity increases pressure decreases

Below the curved upper surface a low pressure zone is created (Air travels further and faster)

Above the flat underneath surface a high pressure zone is created (Air travels less far and slower)

Fluids move from an area of high to low pressure which create the downforce

Downforce - A force pushing downwards on a body
