JEOPARDY

This gas makes up 78% of the composition of the air on Earth.

What is nitrogen.

This gas makes up 20% of the composition of the air on Earth.

What is oxygen.

The attraction of Earth to everything on it.

What is gravity.

The force of air against any object moving through it.

What is air resistance.

A large piece of material that slows things down as they fall

from great heights.

What is a parachute.

The steady speed at which an object falls when air resistance eventually

balances out the affect of gravitational pull on a falling object.

What is terminal velocity.

A large balloon that rises with the aid of hot air.

What is a hot-air balloon.

Gas filled balloons with a motor and propeller

What are airships.

The force that moves a plane forward.

What is thrust.

Friction of air that resists the forward motion of the plane

What is drag.

The force that pulls the plane down toward the ground.

What is gravity.

An upward force caused by a difference in air pressure.

What is lift.

This principle states that as air moves, air pressure drops.

What is Bernoulli’s Principle.

The four main properties of an airplane wing.

What are cross-sectional shape, angle of attack, surface area,

and mass.

A glider that is lifted by wind and attached by a string to the ground.

What is a kite.

The fixed tail unit that helps keep the plane stable.

What is the tailplane.

Structures that extend outward from each side of the airplane.

What are wings.

A moveable control at the rear of the plane that controls direction.

What is a rudder.

A moveable control on the tailplane that allows the plane to climb and descend.

What is the elevator.

A moveable control on the wings that make it bank.

What are ailerons.

The action of a plane’s nose moving from side to side.

What is yaw.

The movement of an airplane’s nose up or down.

What is pitch.

The action taken when one wing is raised and the other lowered

during a turn.

What is bank.What is roll.

The section of the plane where the pilots sit to control the

aircraft.

What is the cockpit.

An unpowered plane that relies on gravity to fly.

What is a glider.

A set of blades that push or pull an airplane through the air.

What is a propeller.

A reusable plane that travels into space.

What is a space shuttle.

A plane that gets its lift from a powered rotor.

What is a helicopter.

An airplane with a rotating blade above it.

What is an autogiro.
