Write some disadvantages of force of friction.

The disadvantages of force of friction are as follows:–

i. As we know that friction acts always in opposite direction of motion, so friction slows down any moving object.


ii. Friction causes unnecessary heat when surfaces are rubbed against each other.


iii. Friction can cause damage to machines having moving parts because of wear and tear.


iv. Friction causes injuries when a person falls its skin gets peeled off due to friction only.


v. Friction makes it difficult to push objects according to mass when we slide them. More the mass more the friction.


vi. Friction cannot be finished completely but can be diminished to great extent.
