Answer:
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 ...
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 a lot of heat in various parts of the machinery and this leads to wastage of energy as heat.
Opposes motion, hence more energy is needed to overcome friction.
Noise production in machines is irritating as well as leads to energy loss.
Forest fires are caused due to friction between branches of trees ...
I hope it will Help ...
