It is an instrument that measurwa 'Wind Speed'.
An anemometer is a device used to measure the speed of wind. It typically consists of cups or blades that rotate with the wind, generating a signal that is used to calculate wind speed. Anemometers are commonly used in meteorology, aviation, and environmental monitoring.
which measures wind speed.
Robert Hooke rinvented the anemometer in 1664. The invention was reinvented again by Wolfius in 1709.
No. The moon has a lack of atmosphere, therefore there is no wind to measure other than the solar wind. I doubt this would register on a standard style anemometer
The "anemometer" is an instrument used to measure wind speed. Its output is a speed measurement, and may be expressed in any convenient unit of speed, such as 'miles per hour', 'kilometers per hour', 'feet per second', etc. Anemometers are sold in units of "each".
An anemometer measures wind speed by detecting the rotation caused by the wind on its cups or blades. The speed at which the cups or blades rotate is converted into wind speed readings that can be displayed on a gauge or electronic display.
