Mass Physics Example 2

Solution

1. 1
   Calculate weight on the Moon: $$W_{\text{moon}} = mg_{\text{moon}} = 75 \times 1.6 = 120 \text{ N}$$
2. 2
   Calculate weight on Earth: $$W_{\text{earth}} = mg = 75 \times 9.8 = 735 \text{ N}$$
3. 3
   The astronaut's weight on the Moon is about $\frac{120}{735} \approx 16\%$ of their weight on Earth, but their mass remains $75 \text{ kg}$ in both locations.
