Lesson details
Key learning points
- 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.
Keywords
