Lever - a bar that helps lift or move things by turning on a point
Pivot - a point around which an object moves or rotates

Common misconception
A lever is just a seesaw mechanism and only moves up and down.
Levers move up and down and the end of the lever moves in a curved direction. Levers can be turned for different effects.
