Answer 2

Answer:

Three situations in daily life where friction is an advantage:

1. It would be impossible for us to walk without friction. It is because of friction between our feet or shoes and the ground that we are able to walk by pushing our feet against the ground. Without friction, we would slip.

2. Brakes on cycles or cars work because of friction. When brakes are applied, the ‘shoes’ of the brakes rub against the wheels. The friction between them reduces the speed.

3. Friction causes nails and screws to hold on to walls, write on paper and even the lighting of matchstick.
