I know that if a space ship suddenly traveled very fast, its astronauts would be fly against the back wall, potentially getting hurt. If the space ship suddenly stopped, they would also fly against the front wall.
Suppose that a space ship could accelerate at a constant rate, e.g.:
Time | Speed ------------------ 1:00 pm | stopped 1:10 pm | 100 Kph 1:20 pm | 200 Kph 1:30 pm | 300 Kph
- As the space ship is accelerating at a constant rate, would the astronauts constantly feel the forward motion of the craft for the duration of their journey?
- Would the astronauts begin to feel that the motion is becoming faster and faster?
- If the space ship continued to accelerate in this manner for many hours, would the astronauts eventually be injured by the great speed?
