When a plane is in flight, what's the main difference between the air below and above its wings?

• The air above the wings has lower pressure

• The air below the wings has lower pressure

• The air above the wings has a higher temperature

• The air below the wings has a higher temperature

Why don't jumbo jets have propellers?

• Because their wings are aerodynamically shape

• Because only helicopters have propellers

• Because jet engines provide more thrust

• Because they are powered be jet fueled, not friction

What can you infer about the airplane parts called "elevators?"

• Manipulating them allows the plane to move up or down

• Manipulating them allows the plane to turn left or right

• Manipulating them allows the plane to go forward or backward

• Manipulating them changes the forces of weight and drag

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
