š Mathematical Formula & Step-by-Step Substitution
- Identify local surface gravitational acceleration on Mars: g = 3.72 m/sĀ² (Earth g = 9.807 m/sĀ²).
- Compute gravitational force in Newtons: F = m Ć g = 80 kg Ć 3.72 m/sĀ² = 297.6 N.
- Compute apparent weight in kg-force relative to Earth scales: 80 Ć (3.72 / 9.807) = 30.32 kg.
- Compare to escape velocity on Mars: v_esc = 5.03 km/s.
