No simple answer - it depends on the item's surface area and its aerodynamic coefficient.
Easy move - a ten square metre sail will move a small boat in a light breeze.
Hard move, a square block of uranium on a checkerplate floor.
More info will help.

How is the rooftop wind turbine different from other wind energy devices?
The rooftop wind turbine is different from other wind energy devices in that it relies on a small motor in addition to wind power, whereas other devices rely only on wind power.
What is another name for a wind tower?
Another name for a windmill is the wind turbine
What is the relationship between air pressure and wind?
pressure = 0.002558 times velocity squared where velocity is miles per hour and pressure is pounds per square foot for example a wind of 75 mph produces a pressure of 0.002558x75x75 = 14 .39 pounds per square foot since there are 144 sq in in one sq ft that is 14.39/144 = 0.1 pounds per square inch In meteorological terms, differences in pressure are what drive wind. Air generally moves toward an area of low pressure. However, due to the rotation of the earth it gets deflected in large scale weather patterns. It is deflected to the right in the northern hemisphere and to the left in the southern hemisphere.
How can wind help shape the earth's surface?
by weathering and erosion
What else besides electricity can wind turbines be used for?
Annoying noise...
Does wind move at the same speed?
No. Wind speed varies greatly depending on the weather.
What speed of wind is required for a wind turbine to generate electricity?
5mph
What instrument is used to predict wind speed?
A series of barometers can be used to predict wind speed and direction. Wind will move from higher pressure areas to lower pressure areas. The higher the pressure differential the higher the wind speed will be.
What determines the speed and direction of clouds?
cloud have no particular direction it move in the direction of wind
How fast do galleons move?
It depends. Sometimes it can move at 20mph and sometimes it will really speed, depending on the wind.
How much does the wind speed affect a windmill?
Wind speed effects how much energy a windmill produces. The faster the windmill goes, the more energy it produces.
What does a fast moving anemometer mean?
Anemometers measure wind speed. And although most anemometers are digital these days, the type dealt with for this expression had needles that would indicate the speed of the wind (much like a needle). When the anemometer would move quickly, it meant there had been a rapid change in wind speed, causing the needle to spin quickly to the left or right.
What is the equivalent wind speed of the Saffir-Simpson scale if the change is made from 1 minute average wind speed to a 3 second gust wind speed?
162 is the base of it and it gives the air to take it from the soil. It is air that the atmosphere always to move in the troposphere.
What is the minimum air speed required to generate electricity in a wind mill?
10 mile/hr
Does a wind sock measure wind speed?
Wind socks measure the direction of the wind when the wind blows into the open end and the sock points the way the wind is blowing. Wind socks can also measure the strength of the wind. If a wind sock is flapping about gently the wind is only light. If a wind sock sticks out in a straight line the wind is much stronger.
How fast do windmills move?
it depends on the speed of the wind, what type of windmill, situation and what it's used for... most windmills don't move extremely fast and they are prevented moving in very strong wind because they can't deal with the speed and can break internally.
An anemometer is used to measure?
An anemometer is used for measuring the speed of wind,
