drag reduction

Drag reduction involves techniques or modifications to minimize the air or water resistance that an object experiences as it moves. This resistance, called drag, slows objects like cars, boats, or planes and causes them to use more energy. By designing shapes that are more streamlined, adding special surface coatings, or using devices like spoilers, engineers can decrease this resistance. The result is improved efficiency, meaning less fuel consumption, higher speeds, and reduced emissions. In essence, drag reduction makes moving objects more aerodynamic and less resistant, enhancing performance and conserving energy.
