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.

18 lip 2024 · What is Drag Force Formula? The drag force formula is a fundamental equation in physics that quantifies the resistance experienced by an object as it moves through a fluid, such as air or water.
Express the drag force mathematically; Describe applications of the drag force; Define terminal velocity; Determine an object’s terminal velocity given its mass
Unlike simple friction, the drag force is proportional to some function of the velocity of the object in that fluid. This functionality is complicated and depends upon the shape of the object, its size, its velocity, and the fluid it is in.
Examples of drag include: Net aerodynamic or hydrodynamic force: Drag acting opposite to the direction of movement of a solid object such as cars, aircraft, [3] and boat hulls. Viscous drag of fluid in a pipe: Drag force on the immobile pipe decreases fluid velocity relative to the pipe. [4] [5]
