Automobiles are four-wheeled transportation vehicles that run on gasoline or electricity. They have become a key component of modern society, revolutionizing the ways we work, play and live.
Cars are complex machines with many parts that all work together to make them go fast and smooth. The heart of a car is its engine, which produces the power to turn the wheels and create electricity to light the inside of the vehicle and operate the radio or stereo.
Other important systems include brakes, steering, lights, a trunk or storage space for luggage and air conditioning. In addition to the engines and other important systems, there are also the tires, which grip the road. The tires are made from rubber or another material that is vulcanized and then formed to the shape of the tire.
Invented in the late 1800s, automobiles have had both positive and negative effects on society. They have helped to give people more freedom and create new jobs. In addition, they have helped to improve highway construction. Many ancillary industries, such as those that produce steel and petroleum, have flourished because of the demand for automobiles.
One of the most significant changes caused by automobiles is that women now have access to jobs and personal freedom they never had before. In the 1910s and 1920s, women drove around with “votes for women” banners hanging from their cars. This caused a major change in American culture. During this same time, the automobile became the main form of transportation in America and made mass personal car ownership possible.
