ABSTRACT
L In the case of Linear Drag, the magnitude of the drag force is proportional to the speed of the moving object with respect to the medium. Linear drag is dominant in situations like that of a small ball bearing falling through still air. The gory details-the size, shape, and composition of the particle, and the relevant properties of the fluid-are all subsumed into a single drag coefficient, b1.
Q For Quadratic Drag, the magnitude of the drag force is proportional to the relative speed-squared of the object. Quadratic drag is appreciable in the motions of an automobile, skydiver, or larger ball through air. Again, all of the details are encapsulated in a coefficient, b2.
