3D Astronaut in Space
Demonstrating Newton's First Law of Motion
Theory
An astronaut accidentally separates from a spaceship accelerating at 100 m/s² in interstellar space. What happens to the astronaut's motion?
Newton's First Law (Law of Inertia):
An object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
Key Points:
- No nearby stars → no gravitational forces
- Spaceship's gravity is negligible
- No atmosphere → no air resistance
- Net force on astronaut after separation: zero
Conclusion:
The astronaut's acceleration becomes zero immediately after separation. They will continue moving with whatever velocity they had at the moment of separation.
