Although friction is very important in everyday life, it also has some disadvantages like:
1-The main disadvantage of friction is that it produces heat in various parts of the machines. In this way, useful energy is expended as a loss in thermal energy.
For example, car engines become warmer due to friction. This could overheat and damage them.
2-Due to friction, you have to exert more power in the machines, to overcome the losses.
3-Opposes the motion, ie, counteracts the movement, so it takes more energy to move.
4-Due to friction, noise occurs in machines.
5-By friction, the engines of cars consume more fuel, which causes a loss of money.
