Learn how to calculate the weight of an astronaut with a mass of 65 kg on Earth using the gravitational field strength of 9.8 N/kg. Perfect explanation for a 13-year-old student.
To calculate the weight of an astronaut on Earth, we use the formula:
Weight (W) = Mass (m) × Gravitational Field Strength (g)
Given:
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).
