How can we increase the
                                                frictional force in our daily
                                                activities?



















                       Anti-slip mats are used to increase       Patterned and rough shoes soles can
                       the frictional force between the wet      prevent us from slipping while walking
                       floor and the mat.                        or running.












                     The mouse pad increases the frictional
                     force between the computer mouse
                     and the mouse pad. Therefore, the
                     movement of the computer mouse is           Patterns on the surface of gloves
                     easily controlled.                          increase the frictional force and make it
                                                                 easier to grip objects.

                                                                     HOTS




                                                                  How does the design
                      Weightlifters use magnesium                 of a safety helmet
                      carbonate chalk powder to lift the          help cyclists move
                      metal barbell. This chalk powder is         faster?
                      used to increase the frictional force
                      and grip to prevent the metal barbell
                      from slipping.
