Flight Unit Review

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
