Question

advantages and disadvantages of friction​

Answer 1

Answer:

Advantages of friction:-

• Friction enables us to walk freely.
• It helps to support ladder against wall.
• It becomes possible to transfer one form of energy to another.
• Objects can be piled up without slipping.
• Breaks of vehicles work due to friction.
• It always resists the motion, so extra energy is required to overcome it.

Disadvantages of Friction:-

• Friction produces unnecessary heat leading to the wastage of energy.
• The force of friction acts in the opposite direction of motion, so friction slows down the motion of moving objects.
• Forest fires are caused due to the friction between tree branches.

Answer 2

advantages of friction

it is because of friction that can be worked drive open doors ,turn tabs And write. screws and nails do not slip off because of the friction between the old and the metal surface of the screw. a knot remains in place the cause of the friction of the rope with which you tie it.bedsheet remains on the bed because of friction. you can sit on a chair without sliding off because of friction.

disadvantages of friction

friction causes the moving parts in machinery and automobiles to heat up this results in wastage of energy and fuel friction also causes wear and tear of the moving parts depending on our requirements we may need to reduce or increase the friction between surfaces.
