š Mathematical Formula & Step-by-Step Substitution
- Identify local surface gravitational acceleration on The Moon: g = 1.62 m/sĀ² (Earth g = 9.807 m/sĀ²).
- Compute gravitational force in Newtons: F = m Ć g = 80 kg Ć 1.62 m/sĀ² = 129.6 N.
- Compute apparent weight in kg-force relative to Earth scales: 80 Ć (1.62 / 9.807) = 13.2 kg.
- Compare to escape velocity on The Moon: v_esc = 2.38 km/s.
