Weight vs MassEasyQuestion 30738

Question

An astronaut's mass on Earth is 70 kg (g = 9.8 m/s²). On Moon (g = 1.63 m/s²), the astronaut's weight is:
  1. A
    70 kg
  2. B
    11.4 kg
  3. C
    686 N
  4. D
    114.1 N
    Correct

Correct answer

114.1 N

Explanation

Weight = mg_Moon = 70 × 1.63 = 114.1 N. Mass remains 70 kg everywhere — it is an intrinsic property. Weight (force) changes with local g.
