* Weight vs. Mass: Weight is the force of gravity acting on an object's mass. It changes depending on the gravitational field. Mass, however, is a fundamental property of matter and remains constant.
* Microgravity: In outer space, especially far from planets or stars, there's very little gravity. This means a person's weight would be practically zero.
* Calculating Mass: To figure out a person's mass, you'd need to use their weight on Earth and the Earth's gravitational acceleration (approximately 9.8 m/s²).
Here's how to calculate the person's mass:
* Formula: Weight (W) = Mass (m) × Gravitational acceleration (g)
* Rearrange to find mass: Mass (m) = Weight (W) / Gravitational acceleration (g)
* Plug in values: Mass (m) = 637 N / 9.8 m/s²
* Result: Mass (m) ≈ 65 kg
Important Note: The person's mass (approximately 65 kg) would remain the same in outer space. However, their weight would be close to zero due to the lack of significant gravitational forces.
