30.3 Bernoulli Effect

According to Bernoulli's Principle, when the wind speed is high, wind pressure is ________

• high

• low

• not enough information

• None of the above

According to Bernoulli's Principle, when the wind speed is low, wind pressure is ________

• high
• low
• not enough information
• None of the above

To generate lift, a blade is angled so the _________ pressure air moves under the blade.

• high
• low
• not enough information
• None of the above

If you blow air between these two balloons, the pressure between the balloons would_________.

• Increase
• Decrease
• Stay the same

The faster a fluid moves, the lower the pressure is in the moving fluid compared to the fluid not moving as fast. This is called

• Archimedes' Principle
• Bernoulli's Principle
• Pascal's Principle
• Vice Principle Snyder

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

The design of a wing:

• causes the air above a wing to move faster than the air below the wing
• helps create lift
• creates a low pressure area above the wing
• all of these answers are correct

Air travels  ______________ over the top of a wing.

• faster
• slower 
• doesn't move at all
• the same speed as

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

According to Bernoulli, as the speed of a fluid increases the pressure exerted by that fluid ___

• Decreases
• Disappears
• Increases
• Stays the same
