Friction is a resistance force that slows down or prevents motion, it is necessary for many applications where you might want to hold items or do things and prevent slipping or sliding.
Friction is used in car brakes, when we walk or climb a hill, making a fire, skiing down a hill, and more.
Friction can be a useful force because it prevents our shoes slipping on the pavement when we walk and stops car tyres skidding on the road. When you walk, friction is caused between the tread on shoes and the ground. This friction acts to grip the ground and prevent sliding. Sometimes we want to reduce friction.
