Below is a link to an excellent website for you to check your learning about weight and weightlessness. It is probably just above N5 standard, so read through it slowly and carefully and ask if there is material you don’t understand.

How does ‘g’ change with height above the surface of the Earth?
| Height from surface of Earth in km | gravitational field strength (N/kg) |
| 0 | 9.8 |
| 200 | 9.2 |
| 400 | 8.7 |
| 600 | 8.2 |
| 800 | 7.7 |
| 1000 | 7.3 |
| 2000 | 5.7 |
| 2600 | 4.9 |
| 2800 | 4.7 |
| 3000 | 4.5 |
| 3800 | 3.8 |
| 4000 | 3.7 |
| 4800 | 3.2 |
| 5000 | 3.1 |
| 6000 | 2.6 |
| 7000 | 2.2 |
| 8000 | 1.9 |
| 9000 | 1.7 |
