Lift: Bernoulli’s Principle

What is an airfoil?

• It is like a cut out or a cross section of a wing of a plane

• It is the part of the plane's wing that is made of foil

• It is a piece of the plane's wing that has been cut out

The airfoil and actual airplane wing have a similar shape. What is this shape?

• Flat tops and curved bottoms

• Curved tops and flat bottoms

• Flat tops and flat bottoms

• Curved tops and curved bottoms

What did Bernoulli study?

• The movement of solids, like steel and bricks

• The movement of molecules and atoms

• The movement of fluids like air and water

When the air hits the wing, we get ______ moving air on top of the wing because of the _______

• slower; curve

• faster; curve

• slower; flat section

• faster; flat section

The slower air on the bottom of the wing is ____ air pressure.

• high

• low

• medium

Using the terms high pressure, low pressure, fast air, slow air, and lift, explain how airplanes are able to fly.
