Sail

A sail is any type of surface intended to generate thrust by being placed in a wind —in essence a vertically-oriented wing. Sails are used in sailing.

Depending on the incident angle of the wind on the surface of the sail, one side of the sail will have a higher air pressure than the other one according to Bernoulli's principle. The difference in pressure will generate lift, causing the sail to be pulled towards the side of lower pressure.

On a sailing boat, a keel or centreboard is used to convert this lateral force into forward movement of the boat with some sideways leaning, or 'heel'.

Thrust: Thrust is a reaction force described quantitatively by Newton's Second and Third Law. When a system expels or accelerates mass in one direction the accelerated mass will cause a proportional but opposite force on that system....

Wind: :For the 1928 film, see The Wind....

Wing: In computing, WinG (pronounced Win Gee) was an API to provide fast graphics performance on Windows 3.1. It was later built-in to Windows 95. In Win32, the equivalent of WinG functionality is provided via API calls such as CreateDIBSection(), SetDIBColorTable(), BitBlt(), and StretchBlt()....
