Drag and lift are two important forces acting on bodies moving through fluids, playing significant roles in fluid mechanics, especially in aerodynamics and hydraulic engineering. Drag force acts opposite to the direction of relative motion between the fluid and the body. It is mainly caused by friction between fluid layers and pressure differences around the body surface. Drag tends to resist motion and increases energy consumption in moving vehicles, aircraft, and pipelines. It depends on factors such as fluid density, velocity, surface roughness, and the shape and size of the body. Lift force acts perpendicular to the direction of fluid flow and is generated
