What I've been taught in primary school about math and physics of motion:
>Your position/coordinates are the basic and most relevant information
>Speed is a just neat way of representing the change of position
>Acceleration is just a neat way of representing the change of speed, ie. Change in change of position
Fast forward past my first worthless degree.
What I'm being taught now, as I try to grasp higher physics:
>Acceleration is the most important thing and the only one with real relevance and tangible effect
>Speed is that thing that changes when you accelerate. Barely matters on it's own and can be safely disregarded most of the time
>what the fuck is a position
Life was easier before humans invented science.

lol OP I laughed sry your thread has no replies

Babbys first
Well, if you weren't a retard you would have realized that the easiest variable to change in a physical system between the three is acceleration, it is also the one that is mostly constant/can be described without respect to time most of the time.
>>9148617
You need to understand the difference between position and coordinates.
>>9149662
I think the jokes accelerates at a high rate at position above you head's coordinates

kek
>speed
>not velocity
you need to go back to your physics classes

The important thing to realize about velocity is that its ENTIRELY relative. So you can't even measure it unless you have two objects. It just doesn't make sense, it would be like trying to measure distance with only one object.
Acceleration is only a rotation in your space time vector. So without any acceleration all vector directions are equally fast at moving through time, this we is why the twin paradox looks like a paradox if you don't consider the acceleration. Bringing acceleration into it, which we know as a rotation of the normally straight vector, we can see that the space time path is no longer a straight line. And a straight line is the fastest way to move though space time(standing still without acceleration). So it makes sense that the twin who had to accelerate twice had to take a longer space time path and will travel slower in time.

Acceleration has nothing to do with the twin paradox. You still have a time discrepancy between the twins even if you don't calculate the acceleration.

>You still have a time discrepancy between the twins even if you don't calculate the acceleration.
not when they meet up
>>9150933
Nope, acceleration is the only thing that makes it so one twin ages less than the other.
You are totally wrong. Explain your argument further if you don't agree.

It's funny how there are so many ways people misunderstand the twin paradox.
I've heard it told and "explained" by people over the years in so many ways.
My favorite is when some people who are not even aware of relativity bring it up thinking that is just refers to difference is how people measure solar time.
>>9150581
How are they different? In my language speed and velocity is are translated with one word.
>>9152087
They are often used interchangeably, but if you want to be precise, speed is just a scalar value that describes the rate at which you move in a frame of reference. Velocity is the entire vector, and it includes the direction in which you're moving.
The way OP used it - it makes little difference.
