Q 6 - The term ‘Dynamic lift’ is explained by …

A - Bernoulli’s theorem

B - Newton’s gravitational principle

C - Kirchhoff’s law

D - First law of thermodynamics

Answer : A

Explanation

For any sort of airfoil producing lift, there must be a pressure imbalance, it means, the lower average air pressure on the top than on the bottom. Therefore, the Bernoulli's principle states that this pressure difference must be accompanied by the speed difference.
