Lever

Picture
A lever is a stiff bar that moves on a fixed point (fulcrum).  A pry bar is a good example of a lever.  A pry bar is used to lift something.  The fulcrum is the point where it touches the floor, the force is your hand that is used to push the bar down.  Using a pry bar makes lifting something easier.  What other examples of levers can you think of?
