Atlantic slave trade and the Industrial Revolution

I truthfully don't know much about the slave trade or the industrial revolution; I don't remember learning about it ever. From what it implies and the basic knowledge I have about slaves, I can guess that it had to do with the trading of slaves from Africa to America. Innocent people of Africa were swept off their country by merchants who then sold them off by a high price to those who needed the physical labor. I'm not quite sure about this, but I think that African kings also sold their people off for goods. I assume that they were mainly sold to work at plantation farms, where they would most likely spend the rest of their lives working and unpaid as well. They were forced to do labor and were not granted the smallest bit of rest nor help. The slaves were basically a part of the possessor's estate, and so would be their offspring. I have no idea what the industrial revolution is, but I assume it had to do with the improvement of the industry and work. Numerous new factories and machines appeared and enhanced the business but required more workers and support. This probably improved the productions and technology at the time and greatly advanced the country economically, but forced labor on people who couldn't handle it.
