Question

Write any one advantage and disadvantage of friction?​

Answer 1

I hope it will help you .

Explanation:

Friction produces unnecessary heat leading to the wastage of energy. The force of friction acts in the opposite direction of motion, so friction slows down the motion of moving objects. Forest fires are caused due to the friction between tree branches.

Answer 2

Friction :

The resistance of the movement of the body over the surface of another body is called as friction...

Advantages :

• it enables us to move freely.

• breaks of vehicles works due to the friction.

• it helps us to support ladder over the wall.

Disadvantages:

• it always resists the motion ,so extra energy is required to overcome it .

• it decreases the life expectancy of moving parts of the vehicles.

• forest fires are caused due to friction between branches of trees .
