An astronaut has a mass of 65 kg.
The gravitational field strength on Mars is 3.7 N/kg.
Calculate the weight of the astronaut on Mars. [3]
- weight = mass × gravitational field strength or $W = mg$ (in any form)(1)
- $W = 65 \times 3.7$(1)
- 240 N allow 240.5 N, 241 N(1)
- Answer: 240 N (240.5 N)
- Examiner tip: Weight is a force so its unit is N; giving the answer in kg loses the final mark.
