What is the definition of Aerodynamics?
The study of how things move using air.
OR
The weight of air pressing against something.
The study of how things move using air.
What is the definition of air?
Invisible particles in our atmosphere, which
mostly consist of oxygen, carbon dioxide and nitrogen.
OR
The weight of air pressing against something.
Invisible particles in our atmosphere, which mostly consist of oxygen, carbon dioxide and nitrogen.
What is the definition of an Airplane?
The force of slowing down an object in flight by
friction or other forms of resistance.
OR
A vehicle used for flight that uses wings
and/or propellers to displace air.
A vehicle used for flight that uses wings
and/or propellers to displace air.
What is the definition of Compress?
The act of flying through air.
OR
The act of pushing (e.g., the pushing of air particles to create flight).
The act of pushing (e.g., the pushing of air particles to create flight).
What are the four forces that act on an airplane during flight?
lift, weight, thrust, and drag.
What is the definition of Flight?
A vehicle used for flight that uses wings
and/or propellers to displace air.
OR
The act of flying through air.
The act of flying through air.
What is the definition of Glide?
The act of moving continuously and smoothly,
used in flights without power.
OR
A force used to move an object in flight in a
desired direction.
The act of moving continuously and smoothly,
used in flights without power.
What is the definition of Propel?
A force that goes against gravity, where it
lowers air pressure on the top of an object to
produce lift and thus, flight.
OR
The movement of an object forward.
The movement of an object forward.
What is the definition of Drag?
The force of slowing down an object in flight by
friction or other forms of resistance.
OR
The act of moving continuously and smoothly,
used in flights without power.
The force of slowing down an object in flight by
friction or other forms of resistance.
Which force pulls everything down towards the Earth?
Gravity
What is the definition of Weight?
The weight of air pressing against something.
OR
The force from gravity’s pull on an object.
The force from gravity’s pull on an object.
What is the definition of Lift?
A force that goes against gravity, where it
lowers air pressure on the top of an object to
produce lift and thus, flight.
OR
A force used to move an object in flight in a
desired direction.
A force that goes against gravity, where it
lowers air pressure on the top of an object to
produce lift and thus, flight.
What is the definition of Thrust?
A force used to move an object in flight in a
desired direction.
OR
The act of pushing (e.g., the pushing of air
particles to create flight).
A force used to move an object in flight in a
desired direction.
BONUS: What are you most excited to learn about in our flight unit?
Answer
True or False: Thrust and drag always work against each other.
True, thrust and drag always work against each other, with thrust propelling an aircraft forward and drag resisting that motion
