               4.  FRICTIONAL FORCE

                 Frictional force is a force of resistance that tries to slow down and stop the movement of
                   objects across a surface.
                 Friction acts on moving objects in a direction opposite to the direction in which the
                   objects are moving.
                 On smooth surfaces less friction is exerted and on rough surfaces more friction is

                   exerted. Due to it we are able to walk. Thus, a top spinning on a smooth wooden table
                   would face less friction than on a rough surface.

                 Examples of frictional force:

                 1.  When we roll a ball on the ground, the ball gradually slows down and stops after some
                    time because of frictional force.
