2 lut 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.

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.

With a doubling of speeds, the drag/force quadruples per the formula. Exerting 4 times the force over a fixed distance produces 4 times as much work. At twice the speed, the work (resulting in displacement over a fixed distance) is done twice as fast.
Express the drag force mathematically; Describe applications of the drag force; Define terminal velocity; Determine an object’s terminal velocity given its mass
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.
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.
