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.
Employers and craft unions opposed the Knights of Labor, and the Knights declined in power after the 1880s. The Knights helped establish the Trades and Labour Congress of Canada (TLC) in 1886, the first central labor body to represent Canadian workers by advocating legislative and political reform.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.
