The drag force is the resultant force exerted on an object immersed in a fluid, consisting of pressure and viscous forces from the fluid. It acts in the direction of the fluid's motion relative to the object and is influenced by the object's size, shape, and the flow's Reynolds number, along with the lift force which acts normal to the flow direction.

- 1. The drag force: The surrounding fluid exerts pressure forces and viscous forces on an object. The components of the resultant force acting on the object immersed in the fluid are the drag force and the lift force. The drag force acts in the direction of the motion of the fluid relative to the object. The lift force acts normal to the flow direction. Both are influenced by the size and shape of the object and the Reynolds number of the flow.
