Question

An aerofoil generates lift because:
  1. A
    It is heavy
  2. B
    Air speed above wing is higher, pressure is lower than below
    Correct
  3. C
    Wing reflects air downward only
  4. D
    Temperature above wing is lower

Correct answer

Air speed above wing is higher, pressure is lower than below

Explanation

Curved upper surface increases air speed above wing → lower pressure (Bernoulli). Pressure differential creates lift.
