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.

∙ 14y agoWe 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.

∙ 13y agou use the falling object model (doesnt include air resistance)

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

What is the device used to mesure pressure and wind?
That is a barometer and an anemometer .
Do you use a hydrometer to measure wind speed?
To measure wind speed you use an anemometer. These are sometimes called wind meters. Meteorologists use anemometers to help predict weather.
What is the use of cup anemometer?
To measure the speed of wind
An anemometer is used to measure?
An anemometer is used for measuring the speed of wind,
What is wind speed measured in?
Wind Speed Is measured In Knots.No, a wind vane only gives wind direction. Wind speed is measure with an anemometer.
What is the device used to mesure pressure and wind?

What would you use to measure wind?
An 'anemometer' measures speed of windAn 'anemometer' measures speed of wind
What measurement is used to mesure air?
a windsock can help you mesure air because when its blowing right you can tell the wind is blowing right
Do you use a hydrometer to measure wind speed?
To measure wind speed you use an anemometer. These are sometimes called wind meters. Meteorologists use anemometers to help predict weather.
Why is the weathervane invented?
it was invented because ppl hav to mesure the wind :)
What is the name of the tool used to mesure wind speed?
An anemometer is the easiest and best way. To tell how fast the speed is using an anemometer, determine how fast the anemometer is spinning with a speedometer if possible.
Who measures anemometer?
An anemometer is used to measure wind speed.
Different instrument use in measuring the wind?
We can use wind socks and wind vanes to evaluate the wind direction and anemometers to measure the wind speed.
How does an anemometer measure weather conditions?
it turns around to mesure the wind pressure* It measures the wind that comes from the Troposphere!!!!!
What do an anemometer use for?
It measures wind speed.
What gauge do scientists use to estimate the wind speed of a tornado?
Scientists usually use the severity of the damage a tornado causes to estimate its wind speed.
How can you use the anemometer?
The Anemometer measures wind speed, not wind direction. Wind Direction is measured by the wind vane.
