Question

Which statement is incorrect about dynamic lift?

Options

Choose one · Correct answer highlighted

It involves pressure differences It is due to viscosity Correct It depends on airflow speed It lifts objects like wings

Explanation

Dynamic lift (e.g., on airplane wings) results from a pressure difference due to faster airflow above (Bernoulli’s principle), not viscosity or gravitational force alone. The incorrect statement is that it’s due to viscosity.
