Aircraft Flight Quiz

What must be equal to weight and drag for an aircraft to travel a straight and level flight?

• Thrust and lift

• Speed and acceleration

• Altitude and pressure

• Fuel and energy

If the lift becomes greater than the weight, the aircraft will _______.

• Decelerate

• Move downward

• Accelerate upward

• Stay at the same level

According to Newton's 3rd Law of motion, what happens when the engine pushes air backward with a force?

• The aircraft moves backward

• The air pushes the aircraft with the same force in the opposite direction

• The aircraft's weight increases

• The air slows down the aircraft

What is the role of drag in an aircraft's flight?

• It helps the aircraft to move upward

• It is the force that makes the engine work harder

• It increases the aircraft's speed

• It generates lift

How does lift contribute to an aircraft's flight?

• It is generated by the difference in velocity between the solid and the fluid (air)

• It acts in a downward direction, towards the center of the Earth

• It is the force that propels the plane forward

• It is the force that the plane moves against

What determines how much lift an aircraft will need in order to fly?

• The color of the airplane

• The rules on how much weight passengers can have in their suitcases

• The size of the aircraft's wings

• The weight of the aircraft

What are the four forces of flight that need to be labeled on the diagram?

• Speed, Direction, Altitude, Duration

• Weight, Thrust, Lift, Drag

• Gravity, Acceleration, Velocity, Momentum

• Pressure, Volume, Temperature, Heat

How is thrust created in a paper airplane?

• By the engine of the paper airplane

• By the forward motion of throwing the airplane

• By the wind resistance against the wings

• By the lift generated from the wings

Why does a plane eventually fall?

• Due to the loss of lift

• Because the thrust overcomes drag

• Because the weight overcomes lift

• Due to the increase in drag

What can cause drag on an airplane?

• The shape of the airplane

• The color of the airplane

• The size of the airplane's windows

• The number of passengers on the airplane
