Sure are a lot of questions about cars. Of course, a lot of us depend on cars to get around. Not too many horse and wagons used anymore. For you question, we asked Pierre Kerr, ac210@freenet.carleton.ca, to help us out.

This is not a question that can be answered easily. Cars are built in large factories using a process called an assembly line. What this means is that there is a long building with car parts placed all along the length of the building. At one end, the frame and body of a car are placed on the wheels. Then the car is moved to the next area where the engine is dropped inside. A bit further down the seats and interior is added. Finally, the windows and lights are added. So at one end of the assembly line is a pile of parts and at the other end is a car that can be driven.

Now, to answer how cars work. The engine and the wheels are the most important parts of a car. The engine takes a mixture of air and gasoline and explodes it in a cylinder. This pushes a piston which then turns the wheels. Here is a simple diagram.

There are some wonderful books in your school library that you should look at.
