swimmer have a lot in common‚ but both have to compensate for the forces of pressure and viscous drag‚ the force of friction that causes a moving object to slow when moving through a substance‚ like air or water. SpeedoUSA in Los Angeles asked NASA to assist in creating a reduced-drag suit shortly after the 2004 Olympics. Manufacturers noted NASA’s elite understanding in areas of fluid dynamics and fighting drag. On the topic‚ Stuart Isaac‚ senior vice president of Team Sales and Sports Marketing said

example‚ they have been engineered in such a way from them being perfectly round‚ to having small indents in them to reduce drag‚ allowing for maximum distance after the ball has been struck. Early techniques such as potential flow did not produce particularly useful results‚ especially in what is now known as D‟Alembert‟s Paradox‚ who predicted that the lift and drag on any closed body was to be zero due to the assumption made that fluid could be treated as “inviscid” meaning the viscous effects

Transgender is a term that is used to describe men and women who were born a certain sex‚ but feel their true gender is the opposite. Some live completely - or part time - as the opposite sex. There are also some transgender people that get sex reassignment surgery‚ completely changing their gender. While the definition of transgender is not yet fully agreed upon and is indeed still changing on a regular basis‚ there are some elements that seem to remain consistent: 1. Not identifying with the

Race the Strip‚ Not the Street. One of the fastest growing worldwide sports right now is racing. There are numerous forms of racing but Street Racing is one that is mainly performed by teenagers. Street racing originated from Drag Racing‚ on a quarter-mile strip. As the sport of street racing began to spread around the early ‘90s‚ people couldn’t really afford to go to a legal track and race‚ and soon enough teens began racing on public streets and highways. Street racing is an adrenaline rush

objects when there is motion.[3] Air resistance‚ also called drag‚ are the forces that are in opposition to the relative motion of an object through the air. Drag forces act opposite to the oncoming flow velocity. Drag‚ unlike other resistive forces‚ depends directly on velocity. Drag is the component of the net aerodynamic force acting opposite to the direction of the movement and the forces working perpendicular are called lift. Drag is overcome by thrust.[4] The coefficient of friction is a

History Main article: History of swimming The sport of swimming has been recorded since prehistoric times; the earliest recording of swimming dates back to Stone Age paintings from around 7‚000 years ago. Written references date from 2000 BC. Some of the earliest references to swimming include the Gilgamesh‚ the Iliad‚ the Odyssey‚ the Bible‚ Beowulf‚ Quran and other sagas. In 1778‚ Nikolaus Wynmann‚ a German professor of languages‚ wrote the first swimming book‚ The Swimmer or A Dialogue on
