An airfoil is

• provides the force of flight called thrust

• made of aluminum foil used to wrap wings

• a shape designed to provide lift when fluid flows over it (curved on top, flat on bottom).

Air pressure is

• the force proving air takes up space

• the force exerted on objects by the weight of air particles.

• the force proving air acts as a fuid

Atmosphere is

• is the air we breathe

• the blue sky above the earth

• the mass of air that can surround a planet.

Bernoulli’s Principle -

• A rule that states that when the speed of a fluid is low the pressure will be low (and vice versa).

• A rule that states that when the speed of a fluid is high, the pressure will be low (and vice versa).

• A rule that states that when the speed of a fluid is high the air pressure will be high (and vice versa).

Burning -

• A chemical reaction that occurs when substances combust to form light and heat.

• An instant reaction that occurs when there is no oxygen.

• A chemical reaction that occurs when someone turns on the lights.

• Streamlining

• Friction

• Compression

To take up less space.

• Expand

• Contract

• Freeze

A backward force that acts to slow down an object moving through a fluid (due to friction).

• Drag

• Thrust

• Lift

• Gravity (weight)
