Q

A large piece of fabric used for landing

A

Parachute

17
Q

Animals capable of flying are

A

Most insects, most birds, bats

18
Q

How can an airplane land?

A

Minimize the thrust (push) caused by the engines, remove the flaps on its wings to change the form, rotate their engines in the opposite direction for a considerable reduction in speed

19
Q

What do the blades on a helicopter do?

A

They help stabilize and control the helicopter.

20
Q

What is Newton’s first law?

A

An object will continue to move unless an external force is applied

21
Q

What is Newton’s 3rd law?

A

The greater mass of an object, the greater force is needed to accelerate it

22
Q

What is Bernoulli’s principle?

A

The higher the pressure, the slower the liquid, the lower the pressure, the faster the liquid

23
Q

Thrust > Drag

A

The plane accelerates

24
Q

Thrust < Drag

A

The plane slows down

25
Q

Weight > Flight

A

The plan descends

26
Q

Weight < Flight

A

The plan rises

27
Q

Thrust = Drag

A

The plan continues at the same speed

28
Q

Weight = Flight

A

The plan remains at the same altitude

29
Q

How does a helicopter fly?

A

They use a motor to turn massive blades, called a rotor, they use the angle of attack required, using Newton’s 3rd law and Brenouilli’s principal.

30
Q

How do rockets “fly”?

A

Rockets don’t really fly, they do not use any of the properties needed for flight. They use carbon, liquid oxygen to create a combustion reaction, it also uses Newton’s 3rd law

31
Q

How do hot air balloons fly?

A

They simply heat up the air inside the balloon. The hot air rises within the balloon, to land, they let some of that hot air escape the balloon

32
Q

Why do your ears pop on airplanes?

A

You have air pockets in your ears, the moment the air pressure is the same, it causes your ears to pop

33
Q

What is drag?

A

The resistance of air, wind or friction, the resistance of any movement

34
Q

What is thrust?

A

Thrust is the movement that steers the object’s direction, flying without thrust is called a stationary flight

35
Q

What is weight?

A

When gravity is pulling on the mass of an object

36
Q

What is flight?

A

The opposite of weight, its something that helps an object fly by lifting it off the ground

37
Q

Air is what?

A

21% oxygen, 78% nitrogen
