The __________ is the line from one side of the wing to the other.

___________ means the aircraft has lost or reduced its lift because its angle of attack was increased too much.

The angle of attack is around 3 degrees before take off.

Reaching the critical angle of attack could lead to an airplane stalling.

____ is a force that acts upon an onject in the opposite direction that it is moving.

____________ means we make objects that have a shape which reduces the drag from air moving past.

The less drag an airplane experiences, the ___________fuel it needs to fly at the same speed.

Which of these is a mechanism that produces drag for falling objects.

An aerodynamic aircraft struggle to fly through the air.

Drag influences how much fuel an aircraft uses.

________ is the force of attraction that pulls together all matter.

Gravity is the biggest obstacle that makes flying a challenge.

____________ is the force of gravity pulling aircrafts to the ground.

The center of gravity of an aircraft is the point it would be possible to balance the aircraft if we suspended it in the air.

Gravity pulls all matter to the centre of the earth.

Lift is what an aircraft uses to overcome its weight.

To make up for excess weight, a plane will have a lower takeoff speed.

________ is the force which moves an aircraft through the air.

A ______ _________ is a machine that converts fuel into a powerful pushing force that we call thrust.

Pilots can accelerate the aircraft by adjusting the _______.

A _________ has spinning blades that generate differences in air pressure between the front and back surfaces of the blades.

Smaller aircrafts will use a propeller in the ______ to generate thrust.

An engine uses fuel to move and accelerate faster.

A propeller spins on its own, causing the lift of an aircraft.
