Question

What are the advantages of friction?

Answer 1

Friction

1. Frictional force is a type of contact force.
2. It starts to act whenever two surfaces are in contact with each other and starts to move over one another.
3. When we apply a force to move an object kept on a surface at the same time frictional force starts to act on the application of that force.

Advantages of friction:

1. We walk freely on a surface due to friction because friction between the sole of our shoes and the ground prevents us from slipping over the ground.
2. Friction helps to support the ladder against a wall.
3. Objects can be piled up without slipping.
4. Breaks of vehicles work due to friction.
