Bernoulli's Principle and Airplane Challenge Quizzizz

Designs that capture the energy of the wind are called ______.

• Air foils

• Tin foils

• Carpet foils

• Trash foils

The scientific principle that describes why planes can fly is called ______ .

• the Fly Principle

• the Lift Principle

• the Airplane principle

• Bernoulli's Principle

Bernoulli's Principle says _____.

• “As a fluid’s speed increases, the pressure within the fluid decreases.”

• “As a fluid’s speed increases, the pressure within the fluid increases.”

• “As a fluid’s speed decreases, the pressure within the fluid increases.”

• “As a fluid’s speed decreases, the pressure within the fluid decreases.”

What part of the airfoil meets the relative wind first? ______________________________________________

• The leading edge

• The trailing edge

• The front edge

• The back edge

On an airplane wing, the trailing edge is at the ___ of the wing.

• front

• back

• side

Based on Bernoulli's Principle, if you want to make an airplane fly, the pressure of the air on top of the airfoil must be (a)   than the pressure below.
