Wind speed is the speed of change in the proportion of atmospheric gases. Affect the wind speed to predict air movement and air and sea navigation. In addition to construction projects and the rate of photosynthesis of plants and other effects are innumerable.

Wind speed measured by anemometer.

Three types of navigation: 1 - Navigation wilderness: and are used in race cars in the desert and during the fishing trips and explorations of the wilderness.

2 - freedom of navigation: used with naval units to guide them from one place to another.

3 - Aviation: the science of guiding the aircraft from one place to another and the ability to locate them at any time during the flight is the most difficult types of navigation.

How does it affect the wind speed on each of: Wind speed affect significantly the navigation and private air traffic because the winds are strong and dangerously difficult navigation in the piece either Maritime Shipping gravity be the second because the wind came and hit the water come out slowly in the form of waves may be significant and may be small, and if we talk about land navigation difficulties we may see a very simple, because the wind speed and do not affect strongly on it.

How to use the wind speed: Used, volatile wind speed when flying before the wind came flying, volatile counter to the pilot of plane impacted to move down before you need to move a lot of momentum and this is called Static friction and after the move is called Kinetic friction Valsuwenh as well as either the car you do not need the wind speed
