WebFor "usual" objects in air and close to terminal velocity, it is the Newtonian drag. F → D = − 1 2 ρ v 2 C D A ⋅ e → v, pointing opposite to the velocity. Here ρ is the density of air, C D the drag coefficient (which depends on the object's shape and orientation, e.g. for a sphere it's 0.47, while for a hollow hemisphere it lies ... Stokes' law is the basis of the falling-sphere viscometer, in which the fluid is stationary in a vertical glass tube. A sphere of known size and density is allowed to descend through the liquid. If correctly selected, it reaches terminal velocity, which can be measured by the time it takes to pass two marks on the tube. Electronic sensing can be used for opaque fluids. Knowing the terminal velocit…

Terminal Velocity - an overview ScienceDirect Topics

Terminal velocity is the maximum velocity (speed) attainable by an object as it falls through a fluid (air is the most common example). It occurs when the sum of the drag force (Fd) and the buoyancy is equal to the downward force of gravity (FG) acting on the object. Since the net force on the object is zero, the object has zero acceleration.
