Principles of flight

Thrust uses which Newton's Law?

• law of inertia

• To every action, there is always an equal and opposite reaction

• F = M * A

• none

Which force use to move an aircraft forward ?

• Drag

• Lift

• Thrust

• Weight

The job of the engine is to propel the aircraft, not to provide lift.

• True

• False

In which year Bernoulli’s Principle discovered ?

• 1758

• 1738

• 1638

• 1658

What AOA means is ?

• Angel of Aircraft

• Angel of Airflow

• Angel of Attack

• None

The direction of lift is always perpendicular, or 90 degrees, to the direction of the wind passing over the wing.

• True

• False

In the case of an aircraft, drag is simply the resistance of the air against the aircraft.

• True

• False

There are two types of drag 1. Parasitic Drag, 2. Induced Drag.

• True

• False

The runner in a tightly fitted running suit would experience much less skin-friction drag than in a fitted fluffy coat.

• True

• False
