Give two examples of situations in which the force of friction is a 'source of help'.​

Answer 1

Here are two examples

1. When we write it is due to friction that pen we use to write is able to write.
2. We stop the car due to the frictional force between road and tyres.
3. While running we do not slip because of friction.

Answer 2

Here's ur answer mate

Friction helps a body to be at place for example

1. We have design below our shoes which creates friction and prevents us from slipping.
2. Pages in books and copies have some sort of rough texture which helps us to write smoothly on a page.
