How are birds able to fly? Is it because of...
Their hollow bones, and the shape of their wings, and the way they flap their wings to generate thrust
The way that they generate thrust
The way they can glide in the air
How would you describe the similarities between a bird and a plane? Or, what is the major similarity that the two have? Please give a detailed answer...=D
They both have tails
They both have wings
They both use lift, and have the same shaped wings
What is the greatest difference between a plane and a bird?
One is an animal and one is a machine
One is bigger than the other
Birds have feathers, and planes don't
Planes are powered by a propeller or a jet engine, whereas birds create their own thrust by flapping
How are helicopters aerodynamic?
The shape of the body is aerodynamic
The shape of the body is aerodynamic, and the blades slice through the air, and how the air hits the airfoil
The way the air hits the airfoil
Birds have microscopic magnets in their beaks, which allows them to know where they are going while flying. So, it's like birds that migrate have a little compass on/in their beaks. True or false?
A bird needs feathers to fly because the feathers provide a strong enough surface to catch the wind. Birds also need feathers to keep themselves warm, and protect them from the rain.

Would you be so kind as to tell me what all the parts of a PROPELLER plane are! =D
Wing
Aileron
Propeller
Fuselage
Flaps
Wheels
Vertical stabilizer/ Horizontal stabilizer
Landing gear
Engine
Rudder
Does thrust push or pull?
Push
Pull
Does drag push or pull?
Does lift push or pull?
Does weight push or pull?
Why do birds flap their wings?
To generate thrust?
To generate lift?
To generate lift, with thrust? So both Lift and thrust
What scenario(s) is drag helpful/crucial in? Please choose a detailed description, so be specific on what you mean! =D
When you are landing a plane, and slowing down in sports (Luge, Bobsleigh, Skeleton, Skiing, etc).
When you're running
In sports and when flying a plane
What part of the plane controls roll?
The rudder
The ailerons
The elevator
The flaps
What part of the plane controls pitch?
The elevators
What two movements make bake?
Roll and pitch
Roll and yaw
Yaw and pitch
What part of the plane controls yaw?
The aileron
Where are the flaps located on the plane
The control surface on the end of the wings
The control surface closest to the fuselage, on the wing
The control surface on the vertical stabilizer
Where is the rudder located on the plane?
The control surface on the horizontal stabilizer
Where are the ailerons located on the plane?
Where are the elevators located on the plane?
What movement(s) is yaw?
Turning side to side while staying level
Nose and tail going up and down
Tilting side to side
A tilting turn
What movement is roll?
What movement is pitch?
What movement is bake?
