To calculate the weight of an astronaut on Earth, we use the formula:

Weight (W) = Mass (m) × Gravitational Field Strength (g)

Given:

  • Mass, m = 65 kg
  • Gravitational field strength on Earth, g = 9.8 N/kg

Now, plug in the values:

W = 65 kg × 9.8 N/kg = 637 N

So, the astronaut's weight on Earth is 637 Newtons (N).

Note: Mass is how much matter the astronaut has, measured in kilograms (kg), and weight is the force due to gravity on that mass, measured in Newtons (N).
