Question

Discuss three situations in daily life where friction is an advantage?

Answer 1

Three situations in daily life where friction is an advantage:
1) Walking - Friction is required between the feet/footwear and the ground to prevents slips.
2) Mechanical Brakes - Mechanical brakes help in slowing down the motion of a machine whenever desired. For example, friction is required to bring a car to rest.
3) Matchbox - Friction between the match stick and the matchbox helps in generating heat; this heat helps in lighting the matchstick.
