weight and mass

Question

An astronaut weighs 600 N on Earth. What will be their weight on the Moon where g_moon = g_earth/6?

RankGuru · Accepted Answer

1. **Weight Relation**: $Weight = mass 	imes gravity$.
2. **Find Mass**: $m = 600 / g_{earth}$. Mass is an intrinsic property and remains **constant** across different planets.
3. **Moon Calculation**: $W_{moon} = m 	imes g_{moon}$.
4. **Substitute Moon Gravity**: $W_{moon} = m 	imes (g_{earth}/6)$.
5. **Result**: $W_{moon} = (m 	imes g_{earth}) / 6 = 600 	ext{ N} / 6 = 100 	ext{ N}$.
