WebA streamlined body is a shape that reduces friction drag between a fluid, such as air or water, and an object moving through it. Drag is a force that slows movement; friction drag is a subset of drag. It happens when the fluid closest to the object stick to its surface, exerting a force that opposes the motion of the object. Webstreamlining When objects move, the air around them generates a type of friction called air resistance, or drag, that slows them down. Fast-moving objects such as cars, trains, and aeroplanes are all streamlined – designed with curved and sloping surfaces to cut through the air and reduce drag. games like cat scratchWebIn addition to swimsuits and caps, swimmers can also reduce drag by having better technique.

Streamlining Increases Friction Drag. The more you streamline an object by elongating its rear surface, the more you reduce the size of its wake and the resulting pressure drag. But elongating an object increases its surface area, and that increases the effects of friction—another form of drag! Making the most of … See more Air flowing past an object pushes harder against the front than the back. This difference creates a backward force called pressure drag. See more As an aircraft's speed increases, drag on the aircraft generally increases much faster. Doubling the speed makes the airplane encounter twice as much air moving twice as fast, causing drag to quadruple. Drag, … See more The air pressure against the leading side of an object is higher than the pressure in the randomly churning eddies of the wake on the other side of it. … See more WebStreamlining doesn't reduce friction, it reduces drag. In air, this is often called air resistance. However, this effect is present is present in any fluid. Streamlining reduces air resistance because it reduces the surface area of the moving object that is …
