Science of Flight Practice Flashcard

Front

What is Newton's 1st Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.

Front

What is Newton's 2nd Law of Motion?

Back

Acceleration is produced when a force acts on a mass. The greater the mass (of the object being accelerated), the greater the amount of force needed to accelerate that object.

Front

What is Newton's 3rd Law of Motion?

Back

For every action, there is an equal and opposite reaction.

Front

What is the purpose of the elevator on an aircraft?

Back

To control the pitch of the aircraft.

Front

What type of camber should be used if an aircraft needs to fly at very fast speeds?

Back

Low camber.

Front

What is a key feature of solar-powered aircraft?

Back

They are powered by renewable energy from the sun.

Front

What is lift in the context of flight?

Back

Lift is the force that directly opposes the weight of an aircraft and holds the aircraft in the air.

Front

What is drag in aviation?

Back

Drag is the aerodynamic force that opposes an aircraft's motion through the air.

Front

What is thrust in aviation?

Back

Thrust is the force that propels an aircraft forward, generated by engines.

Front

What is the role of ailerons on an aircraft?

Back

Ailerons control the roll of the aircraft.
