Show transcript
A lever is a simple mechanism or machine which is useful for lifting things.
A lever allows a smaller force to have a greater effect.
The object you are lifting is called the load.
The force you apply to the load to make an object move is called the effort.
A lever requires different amounts of force depending on where the pivot is positioned.
