WebThe viscosity of a liquid is a measure of its resistance to flow. Water, gasoline, and other liquids that flow freely have a low viscosity. Honey, syrup, motor oil, and other liquids that do not flow freely, like those shown in Figure 7.1.1, have higher viscosities. We can measure viscosity by measuring the rate at which a metal ball falls ... WebMay 22, 2024 · In fluid dynamics, drag is a force acting opposite to the relative motion of any moving object. The force a flowing fluid exerts on a body in the flow direction. Unlike other resistive forces, such as dry friction, which are nearly independent of velocity, drag forces depend on velocity.

WebFriction. Frictional resistance to the relative motion of two solid objects is usually proportional to the force which presses the surfaces together as well as the roughness of the surfaces.Since it is the force perpendicular or "normal" to the surfaces which affects the frictional resistance, this force is typically called the "normal force" and designated by N. WebApr 11, 2024 · The full amount of friction force that a surface can apply upon an object can be easily measured with the use of the given formula: Ffrict = μ Fnorm Two basic experimental facts describe the friction of sliding solids. First, the volume of friction is nearly independent of the area of contact.

WebThe amplitude of the relative sliding motion is often in the order from micrometers to millimeters, but can be as low as 3–4nm.The contact movement causes mechanical wear and material transfer at the surface, often followed by oxidation of both the metallic debris and the freshly exposed metallic surfaces.
