Key Stage 2
Meaning
A force multiplier is a tool to make lifting objects easier.
About Force Multipliers
- A force multiplier can be used to lift things that are too heavy to lift with your hands.
- There are two main force multipliers you should know:
 |
| A lever makes it easier to lift a heavy object. |
 |
| A pulley can make it easier to lift an object. |
Key Stage 3
Meaning
A force multiplier is a tool that increases the size of a force by reducing the distance the force moves through compared to the original force.
About Force Multipliers
- A Force can be multiplied due to Conservation of Energy. Since Work Done = Force x distance then a tool can make the force larger by making the distance shorter.
- There are four main force multipliers you should know:
