Which physical principle explains why an airplane generates lift due to the difference in fluid flow velocities and pressures across the top and bottom surfaces of its wings?
A. Pascal's principle
B. Archimedes' principle
C. Bernoulli's principle✓ Correct Answer
D. Torricelli's law
💡 Solution & Explanation
Bernoulli's principle explains that accelerated fluid flow over the curved upper contour of an aircraft wing creates lower static pressure compared to the bottom surface, generating lift. Other principles like Pascal's law govern enclosed static fluids, while Archimedes' principle accounts for buoyancy forces. This aerodynamic concept remains a fundamental staple in general science exams.
