Definition: DRAG FORCE. Drag Force \(F_D\) is found to be proportional to the square of the speed of the object. Mathematically \[F_D\propto v^2 \] \[F_D = \dfrac{1}{2} C_{\rho} Av^2, \] where \(C\) is the drag coefficient \(A\) is the area of the object facing the fluid, and \(\rho\) is the density of the fluid.
2 Φεβ 2023 · 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.

Drag force can be broken into two types: form drag and skin drag. Form drag is caused by the resistance of fluids (liquids or gases) to being pushed out of the way by an object in motion through the fluid.
The drag force, F D, can be expressed in terms of a drag coefficient, C D, the effective body area, A, normal to the flow, and the dynamic pressure, (rU 2 /2): F D = C D A(rU 2 /2). This expression indicates that the drag on a given body increases as the square of its speed with respect to the fluid, as shown in the diagram.
Drag force FD F D is proportional to the square of the speed of the object. Mathematically, FD = 1 2CρAv2, (6.7.2) (6.7.2) F D = 1 2 C ρ A v 2, where C C is the drag coefficient, A A is the area of the object facing the fluid, and ρ ρ is the density of the fluid.
