What Are Automobiles?


Automobiles are a great convenience and help people get to work or visit friends and family. People are more mobile without having to rely on someone else for rides and can have more time to do things they enjoy. In addition to providing transport, automobiles have opened up the world and created many new opportunities for jobs and places to live.

Most modern automobiles use internal combustion to power the engine, which turns a crankshaft to drive the wheels. This is done by a fuel that goes into the cylinder and explodes, creating air pressure to push a piston down and turn the wheels. Typical fuels include gasoline, diesel, or kerosene. This power is transferred to the wheels by a transmission. A transmission also helps to adjust speed and torque.

The invention of the automobile revolutionized society and gave people freedom and independence. New industries and services grew to support the demand for cars, including manufacturing and repair. The automobile also helped increase leisure activities, which brought about a rise in things like motels, hotels, and amusement parks. But automobiles have also had negative effects on the environment. They produce pollution, and they need roads, which require clearing undeveloped land.
