Answer 2

The listed below points are the examples in which the friction becomes beneficial to us -

1. Friction is the factor which is the main reason for which we can walk upright on the ground. Friction acts between our shoes and the ground and hence we are able to work.

2. When we rub our hands together then production of friction occurs and thus heat is evolved.

3. It is the friction which allows the rubber to erase the writings done with pencil.
