If there is a force in one direction, there is an equal force in the opposite direction. (Law of Flight, Newton's Third Law, Bernoulli's Law of Pressure)
What is Newton's Third Law?
100
Two forces at work on a hot air balloon.
What is gravity and lift?
100
By doing this to the flaps on your glider the nose of the glider will raise and the glider will fly upwards.
What is putting the flaps up?
100
These were invented by Orville and Wilbur write in 1903 in the USA. The first one was called "Spirit of St. Louis" and flew only 40 meters in 12 seconds at a height of 3 meters.
What is airplanes?
200
The force the moves a plane forward
What is thrust?
200
Objects always go from an area of high pressure to low pressure. (Bernoulli's Law of Pressure, Newton's Third Law, Law of Flight)
What is Law of Flight?
200
The first Airships (blimps) used hydrogen gas (which can explode). New Airships use this gas which is much safer.
What is Helium?
200
Doing this to the flaps on your glider will cause the glider to corkscrew through the air.
What is turning one flap up and the other flap down?
200
This was the kind of airplane that was used before 1940 and use something that is very similar to the blade of a fan in order to fly.
What is a propeller-driven airplane?
300
The force that works opposite gravity
What is lift.
300
The faster the air flows, the less pressure it has. (Bernoulli's Law of Pressure, Newton's Third Law, Law of Flight)
What is Bernoulli's Law of Pressure?

This kite is very simple to build and is made by attaching two sticks (spars) to a rectangular piece of cloth or plastic.
What is a Bag Kite?
300
Gliders can be launched in two ways. 1) A giant elastic band known as a bungee cord shoots them into the air like a slingshot. What is the second way?
They are towed into the sky behind an airplane and when they are at the right altitude or height, a lever is pulled which unhooks them from the tow rope to begin gliding.
300
This was developed in Germany during World War 2. It is the most modern airplane that is used to fly many people around at once. It can create a sonic boom when it flies.
What is a jet-driven airplane?
400
A force that works opposite to the direction of travel
What is drag?
400
Pressure on Top of a wing is that it works properly
What is low pressure?
400
In this type of kite the string is attached to a triangle shaped piece of material called the keel. The keel helps the kite stay stable in the wind without needing a tail. They are easy to fly, cheap to make, and commonly sold in stores.
What is a Delta Kite
400
The __________ is used like the rear fin on a shark and helps the pilot steer his glider.
What is the rudder?
400
These can fly but have no wings. They can fly slowly, hover in one place and can take off in much smaller spaces than an airplane.
What is a helicopter?
500
A plane will maintain a constant speed or velocity when these two forces are equal.
What is drag and trust?
500
Pressure under a wing that is caused by slower moving air.
What is high pressure.
500
These kites are usually made with plastic film or paper being wrapped around a wooden frame. They require a strong and steady wind to fly. These kites are sometimes joined together to make one "giant kite" and some are able to lift a person right off the ground.
What is a Box Kite?
500
The up and down movement of the glider is controlled by moving the ____________.
What is the elevators?
500
These were first used in Asia when gunpowder was invented. In the 1920s, an American named Robert Goddard built the first ones that mixed two liquids for fuel. In World War II, Germany invented better ones that travelled farther. Then the USA and Russia developed ones used to carry nuclear warheads, launch satellites and space exploration.
