A car (or motor vehicle) is an international vehicle used to carry passengers. Cars usually have four wheels (circular motions), and an engine or car that moves them.
English Sunbeam-Talbot, since the late 1940s
"Cars" redirect here. For the Disney-Pstrong movie, see Cars (movie).
Edit the name
The word "car" comes from the Greek root "αυτό" (self) and the Latin word "mobilis" (walking). The word means “to walk”, as cars move at their own pace and do not require horses or other external forces to move.
Types of vehicles
Cars are made in different shapes and sizes, for people with different needs. Here are some common types.
It is replaced by a car with a roof that can be opened or removed with an open-drive drive. The Sportier breed is called roadsters.
A hatchback is a small car with a cargo area that uses the same space as a cabinet (instead of a different trunk like a sedan or coupé). They combine the fun of coupés and sedans with the ultimate SUV.
The wagon station (car in English) is a hatchback-like car with a rear window at the bottom with plenty of passengers and luggage.
A delivery truck with a separate cabinet and storage area on the ladder frame. The warehouse is called a "bed".
The sedan (saloon in British English) is a car with a sloping rear window and a trunk with four separate doors.
The coupé (coupe in American English) is similar to the sedan, but usually has only two doors and is considered sportier than the sedan.
An SUV (sport utility car) is a corrupt car with passenger space and integrated equipment (such as rear wheels, station cars, and vans). SUVs are very popular because of their usefulness.
A van is a large box-shaped vehicle designed to carry more passengers or luggage. There are many sizes of bakkies, such as small vans, for families.
Set Power
To make the car move, there must be power to unlock the wheels. This energy can be the chemical energy in gasoline or the electrical energy of a battery. How fast an engine or car can send power to the wheels, and how much power is sent, is called engine power. Car power is usually measured in kilowatts or horsepower.
Fuel
Since 2019, many cars are burning fuel to make an internal combustion engine (sometimes called a "motor"). Power from the engine is then transferred to the wheels by transmission, with a set of gears capable of moving the car faster or slower. The most common fuel is gasoline, called "gasoline" or "gas" in American English.
The cleanest cars are electric cars. It is usually connected to an electrical outlet or a charging station and stores the battery at the bottom of the car. Electric and drive an electric car, turning the wheels. Some electric cars have 2 cars: one in front, one in the back. A few have 4 engines (one per wheel). [5]
The first recorded cars were actually wind turbines attached to carts in the late 18th century. Steam engines were heavy, making the cars slow and difficult to control. Better and faster wet cars began to occur in the late 19th century.
Other power sources Edit
Some vehicles burn gasoline, which is used in large trucks and buses, and a few use wood gas. In some countries, such as Brazil and Sweden, a combination of ethanol and gasoline, called "gasohol" in Brazil and "E85" in Sweden, is used as automotive fuel. Other fuels include propane, natural gas, compressed air and ethanol (from plants). There are cars designed to use more than one type of fuel - these are called "flex-fuel" and are rare.
Few cars generate electricity from hydrogen fuel cells (such as Honda Clarity). As of 2019, the majority of hydrogen users are coming from burning fossil fuels, but scientists and engineers are trying to make hydrogen in renewable energy cheaper and easier to use.
A car that uses solar energy
Some cars even use solar cells to get their electricity, but they do not work very well. There is an annual race where people try to design a car that can last a very long time and go too far with only solar energy.
There is also a car that uses both an engine and an electric motor. This is called a combined electric car; for example Toyota Prius.
Regenerative Brakes Edit
All vehicles have intermediate brakes to stop the car immediately in emergency situations or to roll over when stopped. Electric cars also have regenerating brakes, which speed up the car by converting the energy from its movement back to electricity, like a separate electric car. So renewal means that electricity is reused.
Cars are faster than walking or cycling if you travel long distances. They can carry more than one person and a large amount of luggage. Depending on the local quality of public transportation, they can be faster and easier than using buses, bicycles or trains, and often go where public transportation can be. Four-wheel-drive vehicles "off road" are best suited to access other wheeled vehicles due to bad roads or poor terrain. However, they are more expensive and burn more fuel, and there are more places to go.
Many vehicles lock people and property in a closed room with a roof, doors, and windows, thus protecting the climate. Modern cars offer extra protection in the event of a collision, as they add safety features such as seat belts, airbags, bumps and side protection that may or may not be available in two-wheeled or lightweight 3-wheeled vehicles, or more buses.
Buying and using a car requires a lot of money, especially in new high-end cars. There are things you have to pay for - the car itself, the fuel, parts (for example, tires), maintenance, repairs, insurance to cover the cost of crashes or theft, parking costs, and roads payable and any taxes or license fees paid by the government.
When cars crash, they can injure and injure people, and human life is far more important than keeping the car stable. When too many vehicles try to move in the same direction, traffic jams slow down. Cars can cause air pollution if used too little an area such as the city, and the combined pollution of the world's cars is blamed on part of climate change. Many places where people live close together have public transportation, such as buses, trains, trams, and the subway. This can help people to travel much faster and cheaper than driving when traffic jams are a problem. Some of these problems can be reduced, for example by carpooling, which puts more people in one car.
Traffic jams and accidents can be dangerous for some road users, for example cyclists or pedestrians, especially in an old city built with few cars. Some 20th-century cities were built for transportation. This can cause other problems, such as heavy pollution and traffic congestion, as few, if any, pedestrians. Communities are divided and divided by highways. Pedestrians are at risk if there are too few pedestrian bridges, narrow road bridges or other special crossings.
