  Main Wing

The upward pushing force that causes the glider to climb is?

• Lift

• Thrust

• Drag

• Weight

How is lift generated? (This is important as students will ask you)

• Bernoulli's

  Principle

• Van Gogh's

  Principle

• Da Vinci's

  Principle

• School

  Principal

Answer explanation

Bernoulli's Principle is

The top surface of the wing is curved and the bottom is flat, as the wing moves through the air, the top layer of air travels faster over the curved surface compared to the lower layer

The faster moving air over the top of the wing creates a lower pressure then the slower moving air. This pressure difference results in an upward force call LIFT.

How do gliders stay aloft?

• Magic Wind

• Wind deflected upward by ridgeline

• Just wind

• Thermals from hot surfaces and clouds

Answer explanation

Thermals are parcels of rising air. Glider pilots generally look for clouds as a sign of thermals because the hot air that risers will eventually condense to form clouds

The force that pulls objects towards the center of the earth is called?

• Lift

• Thrust

• Drag

• Weight

Answer explanation

Gravity gives you weight or 1 G.

The forward pushing force produced by the propeller or engine is called?

• Lift

• Thrust

• Drag

• Weight

Answer explanation

As gliders have no engines. The thrust is generated by throwing or chucking hence chuck gliders.

The backward pulling force caused by the planes surface blocking air movement is called?

• Lift

• Thrust

• Drag

• Weight

Answer explanation

Drag has many forms, the one in the slides is also known as form drag or drag as a result of the shape of the plane. So you can encourage your students to sand the plane surfaces down to reduce drag.

Another form of drag is called induced drag. This drag is produced as a by product of lift.

3 Axis of Flight are. They converge where the CG or center of gravity is

• Pitch

• Roll

• Center

• Yaw

The center of gravity is the point at which?

• The fuel of the plane is stored

• the aircraft balances

• the wheels are placed

• most effective point engineered. Most lift is generated as part of research
