How does the streamlined body help to reduce friction - Brainly

Webstreamlining, in aerodynamics, the contouring of an object, such as an aircraft body, to reduce its drag, or resistance to motion through a stream of air. A moving body causes the air to flow around it in definite patterns, the components of which are called streamlines. 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 … WebIn addition to swimsuits and caps, swimmers can also reduce drag by having better technique.

"WebAug 8, 2015 · A: A streamlined body is a shape that lowers the friction drag between a fluid, like air and water, and an object moving through that fluid. Drag is a force that slows down motion; friction drag is a special kind of drag. It occurs when the fluid closest to the object sticks to its surface, exerting a force that opposes the object’s motion. " - How does streamlining reduce friction

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. WebSep 1, 2005 · Streamlining requires swimmers to maintain a straight, tight body position, legs together and arms outstretched with hands adjoined and biceps right next to their ears. This technique, used after dives and flip turns, serves to reduce drag by limiting the frontal area of the body exposed in the direction of motion.
