Help understanding Bell's spaceship paradox
The problem statement of Bell's Spaceship paradox is this:
Two spaceships float in space and are at rest relative to each other. They are
connected by a string. The string is strong, but it ...

Relativistic factor between coordinate acceleration and proper acceleration
I did a recent question about relativistic kinematics here: Generalizing a relativistic kinematics formula for spatial-acceleration dependence.
I have a confusion. In the textbooks I've seen, they ...

Proper time for an accelerating object
As far as I have read so far,
proper time is the time measured on the clock of an inertial frame moving uniformly with respect to another inertial frame. The concept and the mathematical expression ...

Velocity of an object undergoing homogenous acceleration
So I was considering the following problem within the context of Special Relativity:
Given an object O, with initial velocity v, undergoing constant acceleration at a rate of a, I want to express the ...

How an accelerated object sees another accelerated body in special relativity?
Assume two objects are moving with a constant acceleration $a_1$ and $a_2$, which are the measured accelerations by respective object (or constant force being applied to each of the objects). My ...

2 different formulas for proper acceleration derived from the same equation
I was looking at this answer which eventually stated this about the proper acceleration (when $\vec v$ is parallel to $\vec a$):
$$
\vec \alpha =\gamma^3 \vec a = \gamma^3 \dfrac{d\vec v}{dt}=\dfrac{...

Under what conditions is the time component of proper acceleration zero?
Given the magnitude of a proper acceleration, the derivative of proper velocity with respect to proper time, how do you determine what component is from the spatial vs temporal dimensions. I am led ...
