Pushes and Pulls

A force is a push or a pull. That is it! Every time you make something move, you are using a force. Push a door open — that is a force! Pull a drawer out — that is a force! Kick a ball — push force! Tug on a rope — pull force! Forces are invisible, but you can see what they do. They make things start moving, stop moving, speed up, slow down, or change direction.
