Forces of Flight Flashcard

Front

What is the primary force that opposes the motion of an airplane through the air?

Back

Drag is the force that opposes the motion of an airplane through the air.

Front

What is an airplane called that does not have an engine?

Back

A glider is an airplane that does not have an engine.

Front

Which force must be greater than weight for an airplane to take off?

Back

Lift must be greater than weight for an airplane to take off.

Front

When are the four forces of flight in equilibrium?

Back

The four forces of flight are in equilibrium when Lift equals Weight and Thrust equals Drag.

Front

What two parts of an airplane act as an airfoil where one produces thrust and one produces lift?

Back

The wings produce lift and the propeller produces thrust.

Front

Define Lift in the context of flight.

Back

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

Front

What is Thrust?

Back

Thrust is the force that propels an airplane forward, generated by engines or propellers.

Front

Explain the concept of Drag.

Back

Drag is the resistance force that acts opposite to the direction of motion of the airplane.

Front

What role does Weight play in flight?

Back

Weight is the force due to gravity acting on the airplane, pulling it downward.

Front

What happens when Lift equals Weight?

Back

When Lift equals Weight, the airplane is in a state of equilibrium and can maintain a constant altitude.
