Induced drag arises from which force?

Induced drag is directly associated with the lift that is generated by the aircraft's wings. When wings produce lift, they create a pressure difference between the upper and lower surfaces. This pressure difference not only generates lift but also results in vortices forming at the wingtips due to the airflow trying to equalize the pressure. These vortices cause a downward flow of air and create a component of drag known as induced drag.

As an aircraft moves through the air and generates lift, it faces induced drag as a consequence of that lift generation. The greater the lift, typically required during lower speeds or when an aircraft is climbing, the more pronounced the induced drag becomes. Thus, the correct answer is directly tied to the physics of flight, particularly the interaction of forces related to lift.

The other forces, such as thrust, weight, and turbulence, operate differently and do not produce induced drag in the same manner. Thrust is meant to overcome drag and propel the aircraft, weight acts downward due to gravity, and drag resulting from turbulence relates more to the aerodynamic effects of airflow, not the lift-generating process.
