Before we start talking about simple machines there are two important terms you will need
to know:
FORCE: Force can be a push or a pull. For example, if you pull on the handle of a wagon or
cart you are exerting a pulling force. Also, if you push a door open, you are exerting a pushing
force on the door.
WORK: Work is force over a distance. For example, lifting a bucket of water requires you to
exert a pulling force on the handle to lift it off the ground. How far you lift the bucket off the
ground is the distance
