Definition: Drag Force. Drag force \(F_D\) is proportional to the square of the speed of the object. Mathematically, \[F_{D} = \frac{1}{2} C \rho A v^{2},\] where \(C\) is the drag coefficient, \(A\) is the area of the object facing the fluid, and \(\rho\) is the density of the fluid.
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.
Express the drag force mathematically; Describe applications of the drag force; Define terminal velocity; Determine an object’s terminal velocity given its mass
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.
Express mathematically the drag force. Discuss the applications of drag force. Define terminal velocity. Determine the terminal velocity given mass. Another interesting force in everyday life is the force of drag on an object when it is moving in a fluid (either a gas or a liquid). You feel the drag force when you move your hand through water.
