I admire your patience with posters like Centra, keep up the good work.

Patience, are you kidding? He insults me regularly. You know, like you.
Quote from: Origin on 28/01/2022 19:03:52Patience, are you kidding? He insults me regularly. You know, like you.This is a science site and your pseudoscience attitude is insulting. It's also insulting to take time to help you understand a concept and have you ignore it. Purposely or not you are trolling so don't be surprised to be treated like a troll.
so why should they be given equal relative motion?
Granted the velocity would be the same, but the relative motion would not.
Quote from: Centra on 29/01/2022 18:36:59so why should they be given equal relative motion? Because it's exactly as far from A to B as it is from B to A.So, when you write stuff like this, and then say Quote from: Centra on 29/01/2022 18:36:59Granted the velocity would be the same, but the relative motion would not. It looks like you are trolling.Because the time taken is the same, and the velocity is the same, but somehow, you think the distance (which you can calculate by multiplying the same velocity by the same time) is different.Why don't you stop this nonsense?
but the relative motion is split at the barycenter into two sections, that's why
Now Why don't you stop this nonsense of critiquing things which are apparently beyond your level of comprehension?
Because the velocity is the time and distance between the two points but the relative motion is split at the barycenter into two sections, that's why.
It's obvious that it would take 10 times as much energy or force to move a 10 kg object the same distance as a 1 kg object, so why should they be given equal relative motion? If they move apart 100 m then isn't it logical that the 10 kg object should be regarded as having moved 9.090909 m and the 1 kg object 90.90909 m?

We are talking about relative velocity between objects. It takes exactly the same amount of force to maintain the velocity of a 10 ton object as it does a 1 gram object. They both require 0.0N to maintain their velocities.
Uh, you need a source for something which is obvious?
Well, if there were two unequal masses in outer space and a spring between them was released what do you think would happen?
No, YOU'RE talking about relative velocity between two objects,
I'm talking about relative motion based on mass.
Did the two objects start moving in opposite directions instantly and with equal velocity relative to the barycenter between them?
What I stated is exactly what would happen if equal force was applied to both objects in opposite directions with no source of friction or resistance.
Quote from: Centra on 30/01/2022 08:31:55No, YOU'RE talking about relative velocity between two objects,This thread is about velocity, but I guess you forgot. Now you want to talk about acceleration.Quote from: Centra on 30/01/2022 08:31:55 I'm talking about relative motion based on mass.Now you want to talk about velocity again. Relative motion is not based on mass.Quote from: Centra on 30/01/2022 08:31:55Did the two objects start moving in opposite directions instantly and with equal velocity relative to the barycenter between them?It does not matter, one or both objects could have accelerated at any rate in the past it is immaterial.Quote from: Centra on 30/01/2022 08:31:55 What I stated is exactly what would happen if equal force was applied to both objects in opposite directions with no source of friction or resistance.Now you want to talk about forces. Yes a given force will accelerate different mass at different rates. F=ma.
People will say "but uniform motion does not involve accelerating so it would be equally interchangeable between objects of different mass". Maybe, but maybe not.
To get to that uniform motion, one had more kinetic energy added to it than the other.
A 10 kg mass moving away at 100 m/s from the same reference object that a 1 kg mass is also moving away from at the same velocity in the opposite direction has more stored kinetic energy than the 1 kg mass.
Can objects of equal mass, one with no kinetic energy stored and the other with a certain amount stored be considered equally in motion relative to each other?
If there are two equal mass objects with rocket engines on them and rocket fuel is added to one and it fires the rocket until all fuel is consumed, both objects would then have equal mass but one would have the kinetic energy added by that fuel burn. Could you then say that both objects are identical because they are moving apart at the same relative velocity?
The rocket that did not burn fuel could be considered to be moving away from the one that did at the same velocity but would it have momentum and kinetic energy?
Stored energy is a real thing, it can't just be disregarded, so the two objects cannot be considered equal, the one with stored kinetic energy is in motion, the other is not, even though they may appear equally in motion relative to each other.
Two objects moving apart, regardless of how it came about, can be viewed as the two spaces between the barycenter and each object both increasing while maintaining the same ratio.
You know a barycenter is a real thing, right?
Well, if there were two unequal masses in outer space and a spring between them was released what do you think would happen? Would they both move an equal distance from the barycenter?
From the point of view of an ant standing on one of the masses, the other mass moves.That's what relative means.
It's not that simple. The ant also notices the proper acceleration and is not fooled into thinking that his own rock is not exhibiting motion.
Quote"You know a barycenter is a real thing, right?"It's an abstract thing, and one that only applies to orbiting systems, which this isn't. For non-orbiting systems or for systems of more than two masses, it's called the center of mass (CoM), which is real only if you consider abstractions to be real. You can put a small particle near the abstract CoM and the particle will not be necessarily attracted to it, so it isn't real in that sense.
