To end this question I will award andre 1/2 point for getting one of the forces correct.
What two types of forces contribute to the lift on a wing?
Click For Summary
The discussion centers on the two primary forces that contribute to lift on a wing. The first force is the air pressure differential, explained through Bernoulli's principle, which states that faster-moving air over the top of the wing creates lower pressure compared to the higher pressure beneath the wing, resulting in upward lift. The second force is linked to Newton's laws, particularly the third law, which describes the reaction force generated by the downwash of air as the wing accelerates the air downward, creating lift. Additional insights include the importance of thrust, which is necessary for forward motion to generate lift, and the role of the angle of attack, which affects the pressure exerted on the wing. The discussion also touches on the concept of momentum and its relationship to lift, suggesting that the change in momentum of the air diverted by the wing contributes to lift generation. Overall, the conversation emphasizes the interplay of pressure, Newton's laws, and the mechanics of airflow in understanding how lift is produced in aviation.
