0.1 Q: How Much Does a 190 lb Man Weigh on the Moon?

—d

Given:

  • Mass on Earth = 190 lb

  • Convert to kg:
    1 lb ≈ 0.453592 kg
    190 lb × 0.453592 ≈ 86.18 kg

  • Acceleration due to gravity:
    • On Earth: g = 9.8 m/s²
    • On Moon: g = 1.62 m/s²

U — Unknown:

  • Weight (force) on Earth (in Newtons)
  • Weight (force) on Moon (in Newtons)

E — Equation:

  • F = m × g
  • F = Force (in newtons)
  • m = Mass (in kg)
  • g = Gravitational acceleration ( m/s²)

S — Substitute:

Earth:

F = 86.18 kg × 9.8 m/s² ≈ 844.56 N

Moon:

F = 86.18 kg × 1.62 m/s² ≈ 139.6 N

S — Solve:

To get Moon weight in pounds:
139.6 N ÷ 4.44822 ≈ 31.4 lb Because the input in 190 lbs and not 190. lbs, we must use 2 significant digits so the answer is: 31 lb_f —

Final Answer:

  • A 190 lb man on Earth weighs ~31 lb_f on the Moon
  • The force he exerts:
    • On Earth: ~850 N
    • On Moon: ~140 N
