In a brief paragraph identify the investigations that led to factories developing

Factories wouldn't have developed if it weren't for the industrial revolution. The Industrial Revolution wouldn't have happened if it weren't for the great inventions that led its birth. These inventions are the Spinning Jenny, the Water Frame, the Steam Engine and the Locomotive. The Spinning Jenny was a machine that could spin threads of wool. The Water frame was a large wheel that was turned by running water. The Steam Engine used steam to create energy to power a machine. The Locomotive was the first train that could transport people on roads.
