Utopic Motion

For anyone studying kinematics, RM is an acronym related to rectlinear motion.

On this restrictive motion, Einstein constructed the theory of relativity (TRR).

When someone is in a ship with the windows closed, or in
the basement of a ship that goes a lazzy lake, there is no
way to know if the ship crew is standing or moving.

But to what extent the rectlinear motion can be proven?



By observing the above scene, the observer can tell whether the train is in RM - rectlinear motion?

What about the driver, without looking at the speedometer,
you can say that the train is RM?



Well, the Earth is round. The feeling of the driver RM is
possible only in this way, Arched Movement!

If the train, in fact, was running an RM, the profile of
the railroad would have to be like this:



- In R1, the train was going downhill because it is approaching the center of the earth;

- In R2, the train would have finished the descent.

- From r2 to r3, the train was going up the hill, as
distance from the center of the Earth.



Returning to the groundly observer to note that this entire path of train, it will be necessary move the head. The distance between the observer's eyes and the train varies with the trajectory.



If the observer could not parse the railway before being
asked about what he sees, he will have the impression that the line forms an arc of approximately 180 degrees, because he sees the image of the train on their way to turn at a similar angle.



Those traveling by train or bus has a similar feel. Nearby
objects move in high speed, while distant objects almost stand still. Note the green lines, proportional to the relative velocities. When you look at the whole at the same time, the traveler will have the perception of angular motion (in red).



Even the engineer, without consulting the speedometer will
have difficulties in assessing the uniformity of
movement of the train, because the next railway sleeper seem faster than the more distant.



This feeling can be best observed in landing planes. Objects close to the cockpit give the impression of "break
up". Only distant objects are seen clearly.

Einstein, when it was their mental experiences, like
"evoke" trains and railways. The experience of gravity was
based on a lift with steel cable broke.

These machines were available at the time of construction
of their theories. Biplane aircraft already existed, but
were flying at lower SPEED.

The extent to which Einstein considered "angle interference" in their thought experiments?

I booked two short films on the development of Einstein's
ideas.

Question:

Which of the two clocks effectively delayed?
