Does coordinate acceleration match proper acceleration when $v=0, s=0$?

Alice and Bob are riding in their rocket at arbitrary proper acceleration through an arbitrary region of spacetime. Bob steps out of the space ship right next to Alice, such that at $t=t'=0$, $v=0$, ...

Why can gravitational acceleration not be detected by experiments

I was doing research into how $G$ forces are calculated, and I was told that they show all acceleration that can be "sensed" by humans (i.e. all non-gravitational acceleration). This ...

Position / velocity / acceleration vs time graphs when falling towards a black hole

In Newtonian physics, as far as I understand it, for a small object falling towards a massive object, the graphs of position, speed and acceleration vs time look like this: (If the massive object is ...

Are there bounds or measurements on the derivative of acceleration (jerk)

The title says it all. Is there a physical maximum value to the 3rd derivative of position? Common Lore says that there is not and that jerk does not play any role in physics. My guess is that there ...
