m/h, km/h (metres/hour, kilometres/hour), m/h (miles/hour). You can use minutes instead og hours, but it is rarely used. That is you relate the length of your advance to the time during which you did it.
To measure wind speed you use an anemometer. These are sometimes called wind meters. Meteorologists use anemometers to help predict weather.
no you use a stopwatch to measure elapsed time.
You can use a radar gun to measure your break speed. On a simpler level, there is a smartphone app called Break Speed, which does just that.
Anemometer.
To measure the speed of wind.
Red shift.
I guess use a high speed camera Time it and measure the distance travelled.
Doppler radar
There are many ways to measure wind, but most common is Beaufort.
Miles per hour or killometers
anemometer
To calculate average speed, you measure how long it takes(T) to get from point A to point B. Then you use the formula below: speed = (B - A)/T
