What happens to drag when airspeed is increased?

Increase Decrease Remain the same Doubles

Correct Answer:

Increase

Explanation:

Drag is the resistive force opposing motion through air. As airspeed increases, the air’s dynamic pressure rises, boosting the forces that generate drag. There are two main parts: parasitic drag (from friction and form resistance on surfaces) grows roughly with the square of speed, while induced drag (from wingtip vortices) decreases with speed. In typical flight regimes, parasitic drag becomes the dominant contributor at higher speeds, causing the total drag to rise as you go faster. So the best answer is that drag increases when airspeed is increased.
