Stopping and starting



              In this lesson you will learn that forces can make
              things move and stop things moving.                                         Key words

                                                                                          forces
                                                                                          move


















            Some of the cars in the photograph are moving.

            Some of the cars have stopped.

            Forces can make things move.

            Forces can also stop things moving.

                                                                                          any flags
                                                                                          moving?


                                                                                          What is making
                                                                                          the flags move?


                                                                                          Which way are
                                                                                          they moving?
            The flags are not going anywhere.


            They stay on the flagpole and they move backwards
            and forwards in the wind.



                  Stretch zone

               Why do some things move in the wind but others

               do not?
