Bernoulli's Principle states...

• The slower the air is moving, the lower the air pressure.

• The faster the air is moving, the lower the air pressure.

Faster air movement over an airfoil creates  _________ pressure, which in turn allows lift.

• Higher
• Lower

In order to move forward, you must have more  thrust than _______ to fly.

• Thrust
• Lift

• Gravity

The faster air moves, the lower the ________.

• Speed

• Density

• Compression

• Pressure

The study of air in motion.
