Hello Friend,

I hope You understand this

Answer:

Advantages of the friction

• Due to friction, we are able to walk.

• We are able to write because of the friction between the tip of the pen and paper.
• Friction allows us to grip and catch different objects.
• It helps to minimise the speed or to stop the moving objects.
• The things do not move from their places due to friction.

Disadvantages of friction

• Because of friction, the tires and soles of shoes wear out.

• Friction produces heat between different parts of the machines. This can damage the machines.
• It reduces the speed of moving objects so more force is required.
• It does not allow the free movement of objects.
