Question

What are the advantages of friction?

Answer 1

Brakes on a car use friction to stop the vehicles. Since friction is a resistance force that slows down or prevents motion, it is necessary in many applications to prevent slipping or sliding. Friction between the sole of a shoe and the surface of the ground prevents us from slipping.

                         ADVANTAGE OF FRICTION

Friction play a very important role in our daily life. Friction between surfaces provides a grip or hold which keeps the surfaces together.

⇒ Cars and buses are able to move on the road because of friction between the tyres and the road surface.

⇒ The friction between our feet and ground helps us to walk on the ground without slipping and falling.

⇒ Moving vehicles can be stopped by applying brakes only because of friction.

⇒Due to force of friction screw and nails hold in the wood.

⇒You can hold a book in your hand because of friction, otherwise the book  would have slipped from your hands.

⇒The friction between the paper  and pencil enables us to write without the pencil slipping away from the paper.

⇒It would be difficult to sit on chair without friction.

⇒A billiard players depends on the force of friction between the ball and the end of his cue for a good shot.

⇒It is the friction between the belt and the pulley that helps in rotation of various parts of machine.

⇒Friction helps in supporting a ladder inclined  to wall.
