2. Eli Whitney• Invented the concept of interchangeable parts.• Important product parts (like guns) were made exactly the same so individual parts could be changed as needed.• Made products cheaper
3. Mass Production• On an assembly line, a large number of goods are made at one time and all the same.• This made products cheaper than handmade items.

9. Effects of the Industrial Revolution• More and more people moved to cities where there were factory jobs.• This was found more in the North than in the South which remained agricultural.• Products mass produced became more affordable.• As more money was made, machines were improved and new ones invented.
