How weight varies from planet to planet in our solar system
The force of gravity on 1 kg on the surface of different planets varies as shown below.
| Planet | Gravity on the surface, g in N/kg |
| Mercury | 3.8 |
| Venus | 9.1 |
| Earth | 10 |
| Mars | 3.8 |
| Jupiter | 23.4 |
| Saturn | 9.3 |
| Uranus | 9.2 |
| Neptune | 11.2 |

Use a set of bathroom scales to measure your mass in kg.
Then use the table above and the equation:
Weight = mass x gravity to investigate how your mass and weight would vary from planet to planet.
Here is a typical set of results for a student whose mass measured 64 kg.
