In a factory, people and machines make things. They make lots of the same thing. They do it over and over.
Many factories have an assembly line. A product is built step by step. It moves along. A moving belt can carry it.
A toy factory might have doll bodies on a line. Workers add arms. They add legs and heads.
Cars are built in factories. They are built on lines, step by step.
Henry Ford's company built the Model T. His first moving line ran in Michigan.
Ford made so many Model Ts. By 1918, half of all cars in America were Model Ts.
Before factories, most things were made by hand. One worker made them. Or a small team did.
Many early factories sat by rivers. A river turned a big wheel. The wheel ran the machines.
People moved from farms to cities. They went to work in the new factories.
At Toyota, a machine or worker can stop the line. That happens when something goes wrong.
