Flight

1. drag

1.1. is a force that slows you down and works in the opposite direction than you are travelling.

2. low pressure

2.1. When air is moving , it creates areas of high pressure and areas of low pressure. Fast moving air creates an area of low pressure because the particles are spread further apart while high pressure air has particles closer together.

3. lift

3.1. is a force upward. If the force is greater than the gravity force, the object will stay in the air.

4. thrust

4.1. is the force that moves an airplane forward and is usually produced by a plane's engine

5. Bernoulli Principle

5.1. states that the faster the air flows, the less pressure it has.
