Question

disadvantages of friction

Answer 1

DISADVANTAGES OF FRICTION:-

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.
