Aerodynamics, Forces and Flight

Front

What is thrust in aviation?

Back

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

Front

What is drag in aviation?

Back

Drag is the resistance force that opposes an aircraft's motion through the air, increasing when flying into the wind.

Front

What is lift in aviation?

Back

Lift is the upward force that allows an aircraft to rise off the ground, created by the wings as air flows over them.

Front

What is weight in aviation?

Back

Weight is the force of gravity acting on an aircraft, pulling it downward.

Front

What happens when thrust is greater than drag?

Back

The aircraft will speed up.

Front

What controls the yaw motion of an aircraft?

Back

The yaw motion is controlled by the rudder.

Front

What are the four main forces acting on an aircraft?

Back

Thrust, Drag, Lift, and Weight.

Front

How does drag affect an aircraft's speed?

Back

Drag slows the aircraft down, especially when flying against the wind.

Front

When might you feel drag in everyday life?

Back

You might feel drag when you stick your hand out the window of a moving car.

Front

What is the relationship between lift and weight?

Back

Lift must be greater than or equal to weight for an aircraft to ascend.
