People and things always needed to move from one place to another. People are always looking for more convenient or faster ways to travel. Transport is moving people and things from one place to another. Different environments require different modes of transport
People have found machines, vehicles, or crafts to travel. Some vehicles travel on the ground like a train. Some vehicles travel on top of the water as a jet ski. Some even help people travel underwater as a submarine. People use other types of crafts while traveling. The hot air balloon is an interesting way to travel in the sky. For centuries, inventors have developed machines or have designed improved paths to move people faster and faster
Ships and Boats
. The ships are small craftsmen, usually used for special purposes like fishing. Ships are larger crafts that can use sails or engines through water. They can travel on rivers, lakes or oceans.
Boats with Boats
People use flat wooden boards to sort small boats. Another name for an oar is a paddle. The raft is a simple ship with flat bottom. We can make rafts with trunks or logs. Sometimes flat boards, called boards, are connected to make a raft. Some rafts are made of rubber or vinyl. These rafts are often inflatable.
Early Indians made canons from tree trunks. The trunk was emptied and a shovel was used from place to place. Nowadays man-made artificial material, called glass fiber, is a popular material for canoe construction.
Kayaking is a canoe, a canoe with one or two small holes. The holes are where people sit. The competitor may attach waterproof skin or cover to prevent water entering the vessel. The ship may fall completely without sinking. Some people compete in kayak competitions. The kayak event has taken place since the 1936 Olympics.
Boats equipped with sailboats or engines
Other ships and ships use different types of energies. The sailboat uses pieces of canvas or other sails that the wind fills and pushes the ship.
Ancient Egyptians used sails to spread the stones of the great pyramids from Aswan to Giza. The pilgrims traveled from England to a large sailing ship called Mayflower to reach America in 1620.
The motorboat uses an electric motor and propellers. The propellers rotate metal plates that help the ship move in the water. The speedboat is a small but very fast speed boat. Motorboats attract water skiers, help coast guards or sea patrols in rescue missions, or compete in competition.
Larger ships and ships
Most large ships are made of metal, such as iron or steel. Giant propellers driven by motors are used to pass water. The steamer is a big ship with shovels. The steam engine drives the ships to move the ship.
The biggest ships are tankers and aircraft carriers. Oil tankers can carry millions of barrels of oil in huge cargo areas. Designers have built tankers to travel long distances, not oil, to transport water, chemicals or liquefied natural gas.
Aircraft are long, flat warships that operate as a floating air base. The aircraft land on and off the runways at the top of the ship. The submarine is small enough to carry one or two people and stay under water for a few hours. They can be very large, have more than eighty people and stay under water for a few months
The train is a vehicle running on rails or rails. Passenger trains can have many compartments for people to travel from one place to another. Freight trains carry cargo or things. Different cars deliver different types of products
Refrigerators deliver food. Container cars need a crane to lift the cargo in or out of the car. Tanks deliver different types of liquids
People sometimes use the concept of light rail to talk about trains running on the streets of the city. The car, also called tram, is a kind of light rail transport. The first carriages were pulled by horses or even people. Modern sidewalks usually receive electricity.
A subway is a light rail system for cars. A subway runs down the street and underground tunnels. Many big cities have a subway network.
Large trains run on rail tracks. They travel long distances between cities and cities. The first car of the train is the locomotive. The locomotive is driving the train. The first trains used steam locomotives. Today, most trains are able to use petrol or electricity. High-speed trains are electric trains that run faster than a regular train, sometimes a ball train. These high-speed rail systems also carry people in Germany, Korea and Spain. The first country that builds and uses the ball train is France and Japan.
The monorail is another type of train. Most monorail systems run on a single rail. Some monorails will be suspended.
People drive cars in most parts of the world. Cars have wheels and engines. You can drive on many different surfaces. Cars, buses and trucks allow people and things to travel to certain places.
Cars are people that people use from one place to another. Combustion engines are often the power sources of cars. This type of engine runs on petrol or diesel. Some people are worried that combustion engines contribute to air pollution. Electric cars have electric motors that operate on batteries. Some cars use hydrogen to provide energy. The hybrid car uses a combustion engine and a battery to operate the car.
Cars vary in size. The limousine is a long car that occupies a lot of passengers and has a driver. A micro car, also known as a bubble cart, is very popular in countries outside the United States. Car manufacturers have designed to use fewer microns. It is also economical because a small amount of material is needed to build the car
. The fastest cars are racing cars. Some cars have special features, such as convertibles, which have a fabric or a hard top that bends back.
Buses are bigger than cars. The bus has a long body with several rows of seats or benches for passengers. Buses usually operate on schedule. A passenger bus can carry large distances. They travel between different cities. The tour bus carries tourists or people on vacation.
Vehicle engineers have designed trucks to transport all kinds of materials. Pickup trucks are a bit bigger than cars. There is a flat bed behind the cabin. They can carry many things in the flat bed. Large trucks carry different types of heavier materials or equipment. They get to places where trains and boats cannot travel. An 18 wheel is a very big truck. It has 18 separate wheels
Hot air balloons, blimps and dirigibles
Aircraft are vehicles or machines that allow people to travel by air. The first type of air transport was the hot air balloon. This is the oldest successful human transport technology for flight. It uses a large silk or nylon bag filled with warm air. People travel in a wicker basket called thought, hanging under it.
The balloon or the steerable as a balloon. The gas helium fills the balloon to help float. There is a motor that pushes forward. These types of craft were very popular before 1940. Today, advertisers use blues to market their products. Some companies offer sightseeing tours in blimp
Airplanes, sailors, helicopters
An airplane is flying with wings and a motor. In 1903, the Wright brothers received credit for their first aircraft invention. The aircraft are small and can only carry one or two people. Commercial aircraft can be large and many passengers can travel long distances in the long run. The engine drives the propeller. Most major aircraft have jet engines. This type of motor has many pivots. Air is moved much faster than conventional propellers.
Airplanes use turbines to move faster. The army uses supersonic planes, such as warriors or bombers, to move fast with great power. The fighter is a small military aircraft that goes very fast. Concorde is the only supersonic plane used as a commercial aircraft. Passengers were shipped from Europe to America in less than half of the time a regular airplane was flying at the same distance. Concorde was very expensive to fly. Due to increasing costs, Concorde has been withdrawn from use. The last Concorde flight was on October 24, 2003.
The helicopter is an airplane with a large propeller on top. He can get up in the air or take off, straight up. A helicopter can take off without a runway
The glider has a similar aircraft. Only the life uses power. The army can use gliders to transport troops. The gliders are very quiet because they have no engines.
A rocket is a vehicle that is moving into the air at very high speeds. It burns fuel. The thrust raises the rocket. The rocket engine exits from the bottom of the rocket. A lot of energy is needed to get the rocket into space. Energy is needed to make things happen. Astronauts and astronauts are people who travel into space with rockets. The rockets also deliver satellites to their destination. The satellites study the Earth and other objects of the universe
Rocket design and travel
Most rockets are formed by several stages or stages. Each section includes its own fuel supply and rocket engine.
When his fuel is used, a rocket is released. This makes the weight of the rocket easier. Allows you to travel faster. The rocket must travel at least 17,700 miles per hour (28,500 kilometers) to escape from the atmosphere into space, the so-called "escape speed". The part of the rocket that really reaches the place is often called a spaceship.
Some rockets are gaining momentum from boosting missiles. Scientists usually attach the amplifiers to the side of the main rocket. Space shuttle rocket and airplane. It emits two reinforcing missiles. As the rocket uses fuel, it also releases an external fuel tank.
Some key dates in the Transport Development Timeline:
- 1662 – Blaise Pascal invented a horse-drawn road bus.
- 1783 – Joseph Montgolfier and Étienne Montgolfier launched the first balloons.
