There are many disadvantages of friction.
→ Friction causes the soles of our shoes and other footwear to wear away.
→ It produces heat in machines due to friction between the different parts of the machine so a lot of energy is wasted in the form of heat energy.
→ It also produces noise like in machines.
→ It opposes motion so we have to put extra force or put more power.
→ Engines of many automobiles use more fuel because of friction.

Answer:
Disadvantages of Friction
☆ Friction makes moving or sliding heavy objects difficult. A lot of energy is utilised in overcoming friction.
☆ It is responsible for wear and tear of various parts of machines. It also wears out materials like screws, ball bearings or soles of shoes.
☆ Friction decreases the efficiency of machines as a part of energy is lost in overcoming friction.
☆ Tyres of vehicles wear out due to friction. Because of continuous friction between tyres and roads, the groves of tyres dissappear and tyres become smooth. This can cause serious accidents.
☆ Friction produces heat, therefore the engines of cars and other machinery become hot after running for some time and stop working.
