Which term is defined as a force that equals or exceeds gravity?

• A. Wings
• B. Airfoil
• C. Lift
• D. Slats

Answer: (C)

Lift is the aerodynamic force produced by the wings that opposes gravity. As air flows over and under the wing, pressure differences push upward. When lift matches weight, the aircraft flies level; when lift exceeds weight, it climbs; when lift is less, it descends. So the term defined as a force that equals or exceeds gravity is lift. Wings are the physical surfaces that generate lift, not the force itself. An airfoil is the wing’s cross‑section shape that helps create lift, while slats are devices that can increase lift at high angles of attack during critical phases like takeoff and landing.
