WebDrag force is resistance force caused by motion of body through fluid like water or air. This drag force acts opposite to the direction of oncoming flow velocity. Therefore, this is the relative velocity between the body and the … WebDrag 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.
