Answer 2

Friction is a resistance force that slows down or prevents motion. It plays a vital role in our daily lives. It is necessary in many applications where we want to prevent slipping or sliding or where we want to hold a certain item. It helps us apply brakes and make any moving vehicle stop.

Without it we cannot walk hence, no mobility for humans.
