An object has kinetic energy when itâs in motion. The amount of kinetic energy an object has depends on its mass and speed. Potential energy, on the other hand, is a stored energy when an object is at rest. It describes how much work the object could do if set into motion. Itâs an energy we can generally control. When an object is set into motion, its potential energy transforms into kinetic energy.
The Knights of Labor, the first national industrial union in the United States, was founded in Philadelphia on December 9, 1869, by Uriah Stephens (1821-82) and eight other Philadelphia garment cutters.
At the same time, the first industrial unions formed in Canada. The most significant of these unions was the Knights of Labor, which originated in 1869 in Philadelphia, Pennsylvania, and spread into Canada beginning in 1881.he first workers to unionize in Canada were skilled artisans, such as printers and carpenters, whose skills were in demand. Their skills gave them bargaining power, and beginning in the mid-19th century they were able to establish craft unions to protect their jobs and the standards of their work.
