what does Yaw do to a plane?

helps the plane spin horizontally

100

Do wings of a bird help it glide?

Yes

100

What are the parts of the plane that juts out from the sides?

Wings

100

What is a pitch angle?

the angle that the blades on a propeller are tilted

100

What makes a hot air balloon rise? 

When the air inside the balloon is heated. 

200

what does the elevator control?

It controls Pitch

200

Do birds have stabilizers?

No

200

What part of a plane helps create the most thrust?

engine/propeller

200

What is a propeller?

a device with blades which is attached to a boat or aircraft that produces thrust

200

Air cools down inside the balloon and the balloon starts to shrink

What is Hot air Balloons Sinking?

300

An Aileron is used to.....

roll the plane, in other words it is helped to increase and decrease lift on one side.

300

What does a hollow bone represent as a plane?

Fuselage

300

What is the front of a plane (where the pilot will often stay in to control it) called?

Cockpit

300

How does a propeller create thrust?

When the blades (airfoil shape) spin they create a lower pressure in front of the propeller than behind. This lower pressure pulls the plane forward.

300

The ability or tendency to float in a liquid

What is Buoyancy?

400

Control Surfaces work because of....

Air pressure or bernoulli's principle

400

When a bird creates fast air is it low or high pressure?

Low pressure

400

What part of a plane helps control/change yaw?

Rudder and/or Vertical stabilizer

400

What is a rotor?

a sideways propellor that can proivde both thrust + lift for a helicopter

400

Objects that are less dense than water float

What is Archimede's prinicipal

500

Name all of the control surfaces, and what they control (ex. Yaw, Pitch, Roll)

Flaps: pitch, Aileron: roll, Elevator: pitch Rudder: yaw, Vertical Stabilizer: yaw, Horizontal Stabilizer: Pitch

500

Instead of a engine birds have what?

Pectoral muscles

500

What is the name that the body of a plane is called?

Fuselage

500

What is the 2nd rotor on the back used for?

It is used to stabilize the helicopter. The main rotor puts a force on the side of the helicopter, so the tail rotor counteracts that force. Without this the helicopter would spin out of control.

500

What carries the load in the Hot air Balloon

Wicker Basket
