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 = 100 kg Ć 3.72 m/sĀ² = 372.0 N.
- Compute apparent weight in kg-force relative to Earth scales: 100 Ć (3.72 / 9.807) = 37.9 kg.
- Compare to escape velocity on Mars: v_esc = 5.03 km/s.
