Hockey players depend on the ice. They sway from side to side in a constant motion which causes friction to occur between their ice skates and the rink itself.

The bearings don't need friction, but everything else does. It there wasn't any friction it'd be impossible to bolt anything together.
friction
Friction refers to the resistance that one surface or object encounters when moving over another. The two common forms of friction between two sliding surfaces are static friction and rolling friction.
cars are made up of mechanical moving components due to continuous moving ,there is friction between parts to reduce friction and longer life of car we need oil fro car Cars need in in order to lubricate the moving parts. In general, motor oil is the most commonly used oil in a car. This oil is meant to lubricate moving parts such as cam shafts, crank shafts, lifters and pistons. Without oil, these metal on metal contacts would heat up and eventually melt due to the friction created. Oil helps by lubricating the surfaces where moving metal parts meet. In addition, oil helps absorb and dissipate the heat generated by the friction.
