People and things have always needed to move or be moved from one place to another. People have always sought the most comfortable means of travel or faster. Transportation is a way people and things move from one place to another. Different environments require different means of transport.
machinery People have invented, called vehicle or craft, to travel. Some vehicles moving on the ground, like a train. Some vehicles move over the water like a jet ski. Some even help people to travel underwater like a submarine. People use other types of professions to travel in the air. A hot air balloon is an interesting way to travel across the sky.
crafts such as rockets can help people to travel into space. Over the centuries, the inventors designed machinery or improved ways to travel to move people faster and faster.
One of the first ways to transport people and things was traveling in water. The boats are small trades typically used for specific purposes, such as fishing. Ships are major businesses that could use sails or a motor to propel them into the water. They can travel on rivers, lakes or oceans.
Boat With Oars
People use wooden boards called flat pallet line of small boats. An oar is another name for a paddle. A raft is a simple boat with a flat bottom. We can make a raft with tree trunks or logs. Sometimes flat pieces of wood called planks are bonded together to make a raft. Rafts are made of rubber or vinyl plastic called. These rafts are often inflatable.
The first Indians made canoes in tree trunks. They dig the trunk and use a paddle to move from one place to another. Today, an artificial substance made by man, called fiberglass is a popular material for building a canoe.
A kayak is a smoother version of a canoe with one or two small holes. The holes are where people sit. A rider can attach a waterproof skin with water or enclosure to prevent water from entering the boat. The boat can run all the way without falling. Some people participate in kayak racing. The Olympics were a kayaking event since 1936.
Sailboats or Motors
Other boats and ships use different types of power. A sailboat uses pieces of canvas or other tissues called sails, which are filled by the wind fills and pushes the boat forward.
The ancient Egyptians used boats to move the stones to the great pyramids of Giza to Aswan. Pilgrims traveled from England on a tall ship called the Mayflower to reach America in 1620.
A motorboat uses an electric motor and propeller. Propellers turn metal blades that help the ship to move in the water. A speedboat is a small, but very fast motorboat. Speedboats pull water skiers, help the Coast Guard or marine patrol on rescue missions, or may even participate in a race.
Larger boats and ships
Most large vessels are made of metals such as iron or steel. They use giant propellers powered by motors to move in water. A steamer is a great boat with paddles. A steam engine rotates the paddles to move the boat.
The larger ships are tankers and aircraft carriers. Tankers can carry millions of barrels of oil in huge cargo areas. The designers built tankers to travel long distances and other than oil, they can carry water, chemicals or liquefied natural gas.
aircraft carriers are long warships dishes designed to act as a floating air base. Aircraft take off and land on the slopes on top of the ship.
A submarine is a metal vessel that can travel underwater. A submarine can be small enough to carry one or two people and stay under water for a few hours. They can also be very large, has a crew of over eighty people and stay under water for several months.
A train is a vehicle that runs on tracks or rails. Passenger trains can have many compartments for people to move from one place to another. Freight trains carrying goods or things. Different cars carry different types of elements.
food transport refrigerator cars. Container cars need a crane to lift cargo into or out of the car. tank cars carry different types of liquids.
People sometimes use the long-term light rail to talk about trains that run through the streets of the city. Cart, also called a tram is a light rail transport type. The first trams were pulled by horses or even people. Modern trams usually get their power of electricity. Electricity makes things work.
A metro is a light rail system on rail cars. A subway runs on the streets and in underground tunnels. Many large cities have an underground network of tunnels.
Big wheels trains running on the tracks. They travel long distances between towns and cities. The first car of a train locomotive. locomotive power train. The first trains used fumes engines. Today, most trains are getting the power to use gasoline or electricity. Railway trains at high speed electric trains that run faster than a regular train, sometimes called a bullet train. These high-speed rail systems also carry people in Germany, Korea and Spain. The first countries to build and use the bullet train are the countries of France and Japan.
The monorail is another type of train. Most monorail systems run on a single rail. Some are suspended monorails. Train cars actually hang of the track.
People are driving and passenger motor vehicles in most parts of the world. Motor vehicles have wheels and a motor. They can be conducted over many different land surfaces. Cars, buses and trucks allow people and things to get to certain places. They can travel where boats and trains can not go.
The cars are vehicles used by people to get from one place to another. Combustion engines are often the source of energy for cars. This type of engine burns gasoline or diesel fuel to run. Some people worry that the combustion engines contribute to pollution in the air.
The inventors are developing other types of power systems to run cars. Electric cars have electric motors that run on batteries. Some cars use hydrogen to power. A hybrid car uses an engine power and combustion battery to power the car.
Cars vary in size. A limousine is a long drive, which has space for many passengers and a driver to drive the vehicle. A micro-car, also called a bubble car, is very popular in countries outside the United States. Car manufacturers have the microcar designed to use less gas. It is also economical because a small amount of material is required to build the car.
Some people like driving a sports car. The fastest cars are race cars. Some cars have special features, such as convertible with a fabric or hard top that folds back.
The buses are bigger than cars. A bus has a long body with several rows of seats or benches for passengers. The buses usually operate on a calendar. A passenger bus may transport people over long distances. They move between different cities and villages. A tour bus carrying tourists or people on vacation. Some people charter or rent a bus for special purposes.
car engineers designed to transport materials of all kinds. The vans are a little larger than cars. They have a flat bed to the rear of the passenger compartment. They can carry a lot of things in the flat bed. Large trucks carrying different types of materials or heavy equipment. They carry things in places where trains and boats can not travel. An 18-wheeler is a very large truck. It has 18 separate wheels.
Hot Air Balloons, dirigibles and airships
The planes are vehicles or machines that allow people to travel through the air. The first type of air transport was the hot air balloon. It is the oldest successful human charging technology for flight. It floats using a large silk or nylon bag filled with heated air. People move in a wicker basket, called a gondola dangling below.
An airship or dirigible is like a balloon. The helium gas filling the balloon to help him float. It has an engine to push forward. This type of machine was very popular before 1940.
As technology for improved aircraft, people stopped using airships to travel. Today, advertisers use airships to market their products. Some companies offer guided tours in an airship.
airplanes, gliders, helicopters
An airplane is an aircraft that flies using wings and an engine. The Wright brothers receive a credit for the invention of the first aircraft in 1903. The planes may be small and only carry one or two people. commercial aircraft can be significant and carry many passengers long distances in a short time. A motor makes the propellers rotate. Most of the largest aircraft jet engines. This type of engine has many blades rotate inside. They move air much faster than ordinary propellers.
Jet aircraft use turbines to make them move faster. The army uses supersonic aircraft, as fighters or bombers to move quickly with a lot of energy. A fighter aircraft is a small military plane that can go very fast. The Concorde is one of the only supersonic aircraft used as a commercial aircraft. It was carrying passengers from Europe to America, and less than half the time it took for regular aircraft to fly the same distance. The Concorde was very expensive to fly. Due to rising costs, the Concorde was retired from use. The last Concorde flight was on October 24, 2003.
A helicopter is an aircraft with a large propeller on top. It can go up in the air, or take off, upwards. A helicopter can take off without using a track.
A glider has a shape similar to a plane. It uses only the wind for power. The military can use gliders to deliver troops. Gliders are very quiet because they do not have a motor. Some people involved in glider competitions.
A rocket is a vehicle which moves in the air at a very high speed. It burns fuel for thrust. The thrust pushes, or propels the rocket upward. A rocket engine ejects the pushing out of the bottom of the rocket. A lot of energy is needed to propel a rocket into space. Energy is needed to make things happen. Astronauts and cosmonauts are people who travel in space rockets for help. Rockets also transport satellites into orbit destination. Satellites studying Earth and other objects in the universe.
Rocket Design and Travel
sections or multiple steps are the design of most rockets. Each stage contains its power engine and clean fuel rocket.
When its fuel is used, a rocket is released. This lightens the weight of the rocket. It allows him to travel faster. A rocket needs to travel at least 17,700 miles per hour (28,500 kilometers) to get him out of the atmosphere into space, which is the so-called “escape velocity.” The part of the rocket that actually reaches the space is often called a spacecraft.
Some rockets get an extra boost of booster rockets. Scientists generally agree the boosters on the side of the main rocket. The space shuttle is both a rocket and aircraft. It releases two booster rockets. As the rocket uses its fuel, it will also release an external fuel tank. Space shuttle lands like an airplane when he returns to Earth
