About Force Multipliers
- A force multiplier can be used to lift things that are too heavy to lift with your hands.
- There are three main force multipliers:
 |
| A lever makes it easier to lift a heavy object. |
 |
| The force can be made bigger by turning the small gear. The bigger gear will turn with a bigger force. |
 |
| A pulley can make it easier to lift an object. |
