KEY TERMS
An invisible mixture of odourless, tasteless gasses that surround the earth.
What is air?
What Property of Air is shown when you blowing up a balloon, making it expand?
What is air takes up space?
What force propels the plane forward?
What is thrust?
Drag can be reduced using aerodynamics.
What is true?
A propeller is a spinning wing with blades that create lift.
What is true?
The force that acts opposite to the direction of motion.
What is drag?
What property of air is shown by an empty balloon weighs less than a blown up balloon?
What is that hair has weight/mass?
What forces the engine to work harder?
What is drag?
An aerodynamic aircraft struggles to fly through the air.
What is false?
Thrust opposes drag to move an aircraft.
What is true?
The way the air moves around things.
What is aerodynamics?
What property of air is shown when air exerts the same amount of force in all directions on an object?
What is air has pressure?
What force is generated when solid objects move through a fluid?
What is lift?
All drag can be eliminated if the aircraft is designed properly.
What is False?
An engine uses fuel to move and accelerate faster.
What is true?
Whose principal states that in fluid flow, an increase in velocity occurs simultaneously with a decrease in pressure?
What is Bernoulli's Principle?
What property of air is shown when air particles have a lot of space between them so they can be squeezed together?
What is air can be compressed?
What is the force of gravity that acts in a downward direction toward the centre of the Earth?
What is weight?
Some drag is needed for safe landings and to regulate speed.
What is true?
An engine uses the 3rd law of motion - every action causes an opposite reaction?
What is true?
What is the name of the force that propels a flying machine in the direction of motion?
What is thrust?
What property of air can be shown when the higher you are, the lower the air pressure?
What is that air is affected by altitude?
What does an aircraft need to maintain a steady flight?
What is balance?
Drag impacts how much fuel an aircraft uses?
What is True?
A propeller spins on its own, causing the lift of an aircraft.
What is false?
