Uses of Friction. Although you normally hear about trying to reduce or eliminate friction, it actually has some important uses. Since friction is a resistance force that slows down or prevents motion, it is necessary in many applications where you might want to hold items or do things and prevent slipping or sliding.
Friction is a force that exists between two surfaces in contact. Some of the applications of friction in our everyday lives include;
The force of friction between the tyre of a vehicle and the road. The rough surface of the road and the surface of the tyre reduce the possibility of the car skidding off the road.
