2.  When we stop pedalling a bicycle, it slows down and stops moving after some time
                    because of frictional force.



















                 3.  When we rub our palms against each other, they become warm. This occurs due to
                    heat produced by frictional force.






















                 Frictional force has many advantages. Some of them are as follows:

                 1.  We can walk on the ground because of friction between our feet and the ground.
