What are the four forces that affect a plane's ability to fly?
Weight, lift, gravity, and thrust
Weight, drag, lift, and thrust
Gravity, drag, lift, and propulsion
Weight, drag, gravity, and propulsion
Which force must be greater than or equal to weight for a plane to fly?
Drag
Thrust
Lift
Gravity
What is the role of thrust in an airplane's flight?
It pulls the plane upward.
It moves the plane forward.
It pushes the plane downward.
It stabilizes the plane.
How does the shape of an airfoil contribute to lift?
It increases the weight of the plane.
It decreases the thrust needed.
It causes air to move faster above the wing, creating lower pressure.
It increases drag to stabilize the plane.
What is the function of ailerons on an airplane?
To control the plane's speed
To control the plane's altitude
To control the plane's turns
To control the plane's thrust
Which part of the plane is responsible for controlling its climb and dive?
Rudder
Ailerons
Elevators
Propellers
What happens when the elevators on the tail of a plane are raised?
The plane's nose tilts downward.
The plane's nose tilts upward.
The plane turns left.
The plane turns right.
How does a jet engine generate thrust?
By flapping wings
By sucking air in the front and spitting it out the back
By rotating propellers
By using a parachute
What is the effect of drag on an airplane?
It helps the plane to ascend.
It resists the plane's forward motion.
It increases the plane's speed.
It stabilizes the plane's altitude.
Why is the airfoil shape important for reducing drag?
It increases the plane's weight.
It causes air molecules to stick close to its surface, streamlining the wing.
It decreases the plane's lift.
It increases the plane's thrust.
