“DRAG AND LIFT FORCE ” Introduction: Drag Force: The drag force is present everywhere around us. We thrive in a ball of fluids (air and water). Drag forces appear whenever there is motion in air or water or in any other fluid.When objects travel through fluids (a gas or a liquid), they will undoubtedly encounter resistive forces called drag forces.The drag force always acts in the opposite direction to fluid flow. If the body’s motion exists in the fluid-like air, it is called aerodynamic drag. And, if the fluid is water, it is called hydrodynamic drag. ...
