Secondary Metric
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 = 90 kg Ć 1.62 m/sĀ² = 145.8 N.
- Compute apparent weight in kg-force relative to Earth scales: 90 Ć (1.62 / 9.807) = 14.85 kg.
- Compare to escape velocity on The Moon: v_esc = 2.38 km/s.
