A parachute with a larger canopy will create:
more lift
gravity
more drag
The descent of a parachute can be slowed down by:
making the canopy bigger
making the vent bigger
making the load lighter
making it from metal
The pilot of a hot air balloon pulls a cord to open the parachute valve. This causes the balloon to:
Turn left
Ascend (go up)
Descend (go down)
Turn right
Adding a vent hole to the parachute canopy will:
Cause a crash
Make the parachute more stable
Make the parachute rise
A hot air balloon rises because:
It is filled with gas
Cold air is lighter than warm air so it rises
The molecules in warm air are farther apart making it less dense
The pressure inside is higher
All of these are parts of a hot air balloon, except:
Envelope
Parachute valve
Box spring
Basket
Burner
The correct order for the forces of flight is:
1-Drag 2-Lift 3-Gravity 4-Thrust
1-Lift 2-Bernoulli 3-Gravity 4-Airfoil
1-Lift 2-Thrust 3-Gravity 4-Drag
1-Thrust 2-Drag 3-Gravity 4-Lift
What is the name of the green control surface?
Horizontal stabilizer
Aileron
Rudder
Elevators
The blue control surfaces are the Ailerons. They control:
Wind speed
Yaw
Roll
Pitch
Where the pilot and controls are:
Cockpit
Fuselage
Envelope
Vertical stabilizer
The rudder causes the nose of the plane to turn left or right. This is called:
Pitch
Roll
Yaw
Drag
This part is responsible for an airplanes left and right stability. It is called a:
Horizontal stabilizer
Flaps
Diagonal Stabilizer
Vertical stabilizer
An airfoil produces lift by Bernoulli's principle which states:
Slower moving air causes lower pressure and therefore lift.
Faster moving air over the top surface has lower pressure
Slower moving air along the bottom has higher pressure
The difference in pressure creates lift
A spinning propeller creates thrust using Newton's Third Law which states:
Bernoulli copied me.
For every reaction, there is an equal action.
Apples taste good.
For every action, there is an equal and opposite reaction.
To cause this plane to pitch upward, the pilot probably:
Turned the ailerons down.
Moved the elevators up.
Moved the elevators down.
Moved the rudder up.
A crumpled piece of paper falls faster than a flat one because it has less drag. It has less drag because:
It has less weight
It has more surface area to catch the air
It has less surface area to catch the air
Most spacecraft and rockets have very small fins. Why?
You don't need to steer a rocket.
There is no air in space.
They cause too much lift.
I don't know, give me the answer.
This "rocket man" doesn't have wings, he changes direction like a rocket would. He does this by:
Aiming the exhaust.
Kicking his feet.
Trick question, he can't change direction.
If an airplane is cruising at constant speed and height, it must mean:
Thrust = Drag and Lift = Weight
Thrust is greater than Drag and Lift = Weight
If you wanted to cause the plane to Yaw nose to left, you would turn the:
Elevator left
Horizontal stabilizer right
Rudder left
Rudder right
