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.
In Europe, these craft organizations were to be the basis of larger, mass unions uniting workers without regard for trade or, in some cases, industry (Ansell, 2001). This process began in the United States in the 1880s when craft workers in the Knights of Labor reached out to organize more broadly. Formed by skilled male, native-born garment cutters in 1869, the Knights of Labor would seem an odd candidate to mobilize the mass of unskilled workers.
