Flight

Front

What is lift?

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 the engines.

Front

What is drag?

Back

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

Front

What is weight?

Back

Weight is the force exerted by gravity on an object, pulling it towards the Earth.

Front

What is an airfoil?

Back

An airfoil is a shape designed to generate lift when air flows over it, commonly found in wings.

Front

What does it mean to streamline an object?

Back

To streamline an object means to design it in a way that reduces drag and allows it to move more efficiently through air.

Front

What is the relationship between lift and weight?

Back

Lift must equal weight for an airplane to maintain level flight.

Front

What is the purpose of airplane wings?

Back

Airplane wings are designed to create lift, allowing the airplane to rise into the air.

Front

What happens to thrust if an airplane engine fails?

Back

If an airplane engine fails, thrust decreases almost immediately.

Front

What does 'counteract' mean in the context of forces?

Back

Counteract means to balance out or oppose another force.
