Question

Discuss the benefits of friction.

Answer 1

Benefits of friction are as follows:

• It is not possible to even walk on the road; in the absence of friction. Walking on ice is almost impossible because of lack of friction.
• Friction is necessary to keep a ladder against a wall. The ladder will not find grip against the wall in the absence of friction.
• It is very difficult to drive on a wet road because of less friction. A thin film of water is made over the surface of road. This thin film of water greatly reduces friction. Due to this, the driver finds it difficult to control the vehicle while driving on a wet road.
