How much does 120 kg weigh on Europa (Jupiter Moon)?

⚔ Instant Calculated Answer

An object with a mass of 120 kg weighs 16.08 kg-force (157.2 Newtons) on the surface of Europa (Jupiter Moon), which is 13.4% of its weight on Earth.

16.08 kg Primary Metric
157.2 N Secondary Metric

šŸ“ Mathematical Formula & Step-by-Step Substitution

\[ F_g = m \cdot g = 120 \text{ kg} \times 1.31 \text{ m/s}^2 = 157.2 \text{ N} \implies W_{kgf} = 16.08 \text{ kg} \]
Weight = 120 kg * 1.31 m/s^2 = 157.2 N = 16.08 kg-force
  1. Identify local surface gravitational acceleration on Europa (Jupiter Moon): g = 1.31 m/s² (Earth g = 9.807 m/s²).
  2. Compute gravitational force in Newtons: F = m Ɨ g = 120 kg Ɨ 1.31 m/s² = 157.2 N.
  3. Compute apparent weight in kg-force relative to Earth scales: 120 Ɨ (1.31 / 9.807) = 16.08 kg.
  4. Compare to escape velocity on Europa (Jupiter Moon): v_esc = 2.02 km/s.
