WebLike friction, the drag force always opposes the motion of an object. 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. WebThere are eight drag laws for the particles that can be selected from the Drag Lawdrop-down list under Drag Parameters. The spherical, nonspherical, Stokes-Cunningham, and high-Mach-numberlaws described in this sectionin the separate Theory Guideare always available, and the dynamic-draglaw described in this sectionin the separate
