In what places do you use wind?
We use wind in places like windmills, for wave energy, at sea: pushing the sail of a boat, etc.
Does a sail make the boat move slower or faster?
Actually, it does both depending on how you use them. The sails can move so a person sailing a boat can catch the wind by how they move the sail or they can also stop the boat by the movement of a sail or lowering the sail.
What are things that use Wind energy?
Wind mills, sail boats, kites, birds.
How is wind energy used now?
wind is used everywhere! we use it to sail and we use wind turbines on farmland,mostly in rural areas.
How does wind energy generate energy?
Wind energy can be transformed to a suitable form for human use. It could use turbine connected with dynamo to generate electricity. It could connect the turbine with gear and use the mechanical energy transformed to pump the water or operate a mill. It could use sail to catch the momentum of the wind to sail the ship.
How can wind be used to produce energy?
Windmills are used to convert wind into useful energy. Sail boats also use wind to produce motion, and hence kinetic energy.
Sail boats and kites use what kind of energy?
Wind motion is the type of energy used by kites and sailboats.
What is one wind system you can use to travel around Earth?
Prevailing winds can be used to help navigate ships and sailboats around the Earth by sea.You can sail a ship around this world even against the wind using wind energy. By picking up speed using wind then use kinetic energy gained to sail against the wind direction. So, yes, even with one wind direction we can sail the globe both ways.
How does a sail work?
Different sails work differently. Sailboats tend to catch wind and cause the boat to be pushed by this action. The more square footage of sail you have the more power you are sailing with. Ice boats use the sail as a wind edge. They do better when going into a wind. The wind passes over the sail on both sides. One side has more pressure then the other side. As a result, the ice boat is capable of moving several times faster then the wind. Speeds of as much as 100 mph have been recorded.
How does a sail make a boat move faster?
It captures the available wind power, putting it to use in moving the boat. The sail interupts the wind in it's course, and naturally moves forward. As the sail is attached to a mast which itself is attached to the boat, it drags the boat along with it.A little more...The above is most accurate when running before the wind. Sails on almost all points of sail except running act more like a wing than a parachute, creating a low pressure zone in front of the sail (which sailors, pilots, and aerodynamic types call "Lift"). This low pressure zone sucks the wing or sail forward or up. The boat is indeed pulled in that vector, either at the points of attachment to a mast or a stay.
What are 2 examples of how people use wind to their advantage?
People built wind mills as a way to provide energy to grind flour. Sailors used wind to sail across the oceans.
Is a sailing boat is powered by the wind?
Most of the time. Some are powered by motors, but all of them have the sails (different numbers for different kinds of ships). The wind catches in the sails and moves the boat. Depending on the angle of the sail, the ship can move in almost any direction. Though it is easiest when the wind is right behind the boat. When the wind is blowing in the opposite direction you want to go, then there is a technique that you can use called "tacking".
