Advantages of friction:

  1. We are able to walk on ground because friction between the sole of our shoes and ground prevents us from slipping over the ground.
  2. Friction between tyres of a car and the road enables a car to move forward on road without skidding.
  3. The brakes of a car or a bicycle work by friction.
  4. We are able to write and make drawings on paper because there is friction between the tip of pencil and paper.
  5. We can hold a glass tumbler in our hands because of friction between the glass tumbler and our hands.
  6. We are able to fix nails in a wall due to friction.
