- Drag force in fluid mechanics refers to123:
- A force acting opposite to the relative motion of an object moving through a surrounding fluid.
- It can exist between two fluid layers, two solid surfaces, or between a fluid and solid surface.
- Generated by the relative velocity between the solid object and the fluid.
- Acts in a direction opposite to the object's motion.

This can exist between two fluid layers, two solid surfaces, or between a fluid and solid surface.en.wikipedia.org/wiki/Drag_(physics)The resistance offered by a fluid, like air and water, is called the drag force or drag when an object moves through it. It acts in a direction opposite to the object’s motion. It is generated by the relative velocity between the solid object and the fluid.www.sciencefacts.net/drag-force.htmlDrag 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 fluid.www.toppr.com/guides/physics-formulas/drag-forc… - People also ask
