By repeating what the OP clearly already knows, you answered nothing. The other answers are equally useless. What the OP wanted to know is why does the vector expression for drag---the one that he wrote down and the one that you repeated back to him/her---work. flowers north shore private hospitalIn fluid dynamics, drag (sometimes called fluid resistance) is a force acting opposite to the relative motion of any object moving with respect to a surrounding fluid. This can exist between two fluid layers (or surfaces) or between an fluid and a solid surface. Unlike other resistive forces, such as dry friction, which are nearly independent of velocity, the drag force depends on velocity. Drag force is proportional to the velocity for low-speed flow and … greenberry sulphur louisiana

"In fluid dynamics, the drag equation is a formula used to calculate the force of drag experienced by an object due to movement through a fully enclosing fluid. The equation is: • is the drag force, which is by definition the force component in the direction of the flow velocity, • is the mass density of the fluid, " - Drag force equation explained
