A Measure in one direction is called?
A measure in one direction is called a vector. Some specific vectors are length, width, height and radius.
There really isn't something to measure the amount of wind, I believe that you are referring to wind speed and direction. The instruments that are used to measure wind speed is the anemometer. Also, for wind direction, we would use a wind vane. You can feel the direction of wind.... I guess humans are like one giant wind vane!
An anemometer is used to measure velocity and is the spinning part on a weather station. A weather vane is an instrument for showing the direction of the wind. They are typically used as an architectural ornament on the highest point of a building. On a sailboat, the vane at the top of the mast is called a windex.
