                       Imagine you are on a playground.


                       What forces do you use when you


                       play on some of the equipment


                       there?








                                                  example



               I like to play on a swing on the


              playground. A swing doesn’t move until a



              force is applied to it. When I pump my


              legs on a swing, it starts to move. If my


              friend pushes a person on a swing hard,



              that person moves faster and higher.


              Then, I slowly stop when I drag my feet



              on the ground.
