Bernoulli's Principle & Lift

What is the main purpose of lift in flight?

• To slow down the airplane

• To push the airplane upwards

• To make the airplane heavier

• To change the airplane's direction

What is an airfoil?

• A type of bird

• A streamline design shape that is curved on the upper surface and flat on the lower surface

• A type of car

• A type of boat

What is the primary function of an airfoil shape in nature?

• To absorb sunlight

• To store water

• To provide shelter

Why is the top of an airplane wing curved?

• To create an area of low pressure above the wing
• To create an area of high pressure above the wing
• To create equal pressure above and below the wing
• To make the wing look really cool

What is the best depiction of Bernoulli's principle below?

• As the pressure of a fluid decreases, the speed increases

• As the pressure of a fluid increases, the speed increases

• As the pressure of a fluid decreases, the speed decreases
