What do you use to mesure the speed of the wind?

Answer 1

No, but you can calculate it, using conservation of momentum. Conservation of momentum can be verified experimentally in less extreme cases; in the case of the Earth moving towards the falling object, the movement is just too small to detect.

Answer 2

We have to assume that you can neglect the effects of air resistance, and the only influence on the rate of fall is gravity.

We also have to assume that the object starts from rest, i.e. somebody dropped it but didn't throw it down, so it starts falling from zero speed.

The distance it drops in ' t ' seconds is ( 1/2 G t2 ).

' G ' is the acceleration of gravity ... 9.8 meters per second2, or 32.2 feet per second2, depending on how you want the answer.

So, to answer the question:

-- Time the falling object with a stop-watch. Take the number of seconds it took to fall.

-- "Square" the number of seconds. (Multiply the number by itself.)

-- For meters, multiply by 4.9 . For feet, multiply by 16.1 .

That's all there is to it.

Answer 3

Anemometers are commonly used to measure the speed of wind. They typically consist of cups that rotate in the wind, and the rotation speed is used to calculate the wind speed. Other methods include using a weather vane or a handheld anemometer.

Answer 4

u use the falling object model (doesnt include air resistance)

Answer 5

There are many different instruments used to determine the speed, these are called anemometers.

the unit for wind is mph, (miles per hour)
