DISADVANTAGES OF FRICTION
Despite the fact that the friction is very important in our daily life, it also has some disadvantages like:
1. The main disadvantage of friction is that it produces heat in various parts of machines. In this way some useful energy is wasted as heat energy.
2. Due to friction we have to exert more power in machines.
3. It opposes the motion.
4. Due to friction, noise is also produced in machines.
5. Due to friction, engines of automobiles consume more fuel which is a money loss.
6. Machine efficency is decreased: energy input is lost to heat
7. Getting shocked by doorknobs
8. Rug burn
9. It counteracts movement and so it takes more energy to move, it can cause unwanted heat (e.g. in machine parts), and it wears things out like shoes.
10. Forest fires are caused due to friction between branches of trees

wear tear of mechanical parts
lots of heat generated by this work duration will decrease
motor vehicles motors get heated and performance of its engine is decreased
due to excess friction parts may struggle to move and function is delayed
