Cable spreading room at Point Tupper. In the electrical wiring of buildings, a cable tray system is used to support insulated electric cables used for power distribution and communication. Cable trays are used as an alternative to open wiring or electrical conduit systems, and are commonly used for cable management in commercial and industrial construction.
Static friction must be overcome. Once a force has been applied that starts the object in motion, the force of kinetic friction is less than its static counterpart. 1 person found this useful. Edit.
Sliding friction is stronger when an object is stationary (this is called static friction) than when the object is in motion (this is called kinetic friction). When trying to move a box, it is often harder to get the box moving than it is to keep the box in motion.
