Bill Vajk I don't dispute that a state of acceleration can be discovered and as a binary attribute that can be absolute. The moment one gets past binary answers one is instantly in the realm of relative values including an external baseline (value system.) End of trivial word games. Old Man has mottling new to say. Vajk is stuck with his whimsical and silly definitions of "absolute" and "relative". There is no physics in this. [Old Man] OK, you're stuck in "engineering caliber physics" forever then. Best to you. |

Drop a turd. That is your absolute measurement and proof of an accelerated frame of reference, you spewing jackass. If mass has weight then your reference frame is accelerated. It is an absolute measurement made in a hermetically sealed and isolated environment without reference to the fixed stars. I'll explain this once more slowly and using small words. The fact of acceleration is an absolute and can be determined without comparison. The measurement of acceleration requires reference and is relative. A simple definition of acceleration is the rate of change of velocity with respect to time; broadly : change of velocity. (gratis m-w.com) Change? Oh gee whiz, compared to what? Absolute? Heck no. Hey schmuck, do you float up into the air at night when your locked bedroom is all dark and scary? You should drop science altogether as insults are your only forte.

You should drop science altogether as insults are your only forte. Even your butt buddy Nil Dilated is keeping put of this one. You are slowly twisting in the wind, idiot. Once again you prove that what I wrote about you is true. Next we'll be reading that Littlemanwearingbigboypants is such an absolutist that he's turned determinist as well. Join Relf in the realm of creative writer with *some* smatterings of science in the hash as that's where you belong. LOL P.S. You seem to be having memory problems. Anything to do with late stage syphillis? I am not homosexual. That being said, if I were I wouldn't be ashamed of it, so your pathetic attempts at insult by such aspersions falls flat in every way. P.P.S. I don't need anyone's support or approval when I call you out for being wrong as you were this time, AGAIN! I can successfully do it with half my brain tied behind my back. |

Some of us computer scientists were sitting around, bored, and decided to nudge the Earth towards the Sun. It'd be convenient if it would hit within our lifetime, so we could finish at least one project on time and under budget in our lifetimes! I'm not a physicist, nor did I take enough math or physics to figure this out, so would like your help. My guessing says we have to slow the Earth's rotation so that its gravitational acceleration to the Sun overtakes it's angular momentum, allowing us to smack into the big one. How much force is required to slow us down enough so that the big splashdown is within 50 years? Thanks much Absolute acceleration. Hahahahahahahaahaha I was laughing all night last night. Hahahahahahahahahahahahaha Ok, let's concede that all acceleration is absolute otherwise we may end up with objects in a free fall experiencing an acceleration depended on their mass. Hahahahahahahahaha Anybody knows if "jerk", da/dt, is absolute too? hahahahahahahahahah I have a suspicion that we must invent the term "absolute integration". Hahahahahahahahahaha Hey Jimbo, I have absolute on the rocks. |

Old Man wrote: This isn't physics. Vajk has reduced this thread to a play on words. The local speed of light is absolute. That's not completely true either. http://arxiv.org/pdf/gr-qc/9712076. Speaking of equivalence principle challenges.... Beyond that, define "speed" in absolute terms. You cannot. snip The key is "local" without reference to anything that's non-local. End of word game. [Old Man] You're playing a word game to the hilt, Ole Man. Every unit of measure depends on a comparison to a standard and is relative to that standard. The units you use to describe "speed" etc. are all external and non-local. You can't get around it no matter how much you pout, they're relative. Your rabid anti-Al-ism has led you to make some rather large gaffes in this thread. None of this has anything to do with what "relative" and "absolute" mean as they are used in physics. What you are talking about is the completely separate issue of defining units of measure. If I say an object is moving, relative to me, at 4 m/sec, I mean that I have calibrated my equipment against agreed standards for the meter and the second, and in terms of those standards, the object's position is changing at a rate of 4 meters every second, within measurement accuracy. That is the object's velocity relative to me. I do not do some sort of ratio of the object's motion to my motion since, from my point of view, I have no motion. "Relative velocity" means the derivative of position with respect to an origin. It is relative to that origin. You may look at the same object and conclude that the motion is 10 m/sec, again within measurement accuracy. The fact that we disagree is not due to problems with the standard or problems with somebody's equipment. It's due to the fact that our origins are in relative motion, again as calibrated against those standards. The statement "velocity is relative" is a shorthand for the concept that neither of us can say that one is right and the other is wrong, that neither origin is necessarily preferable, PROVIDED both our coordinate systems are inertial (and that has a separate technical meaning). A state of constant relative velocity can be defined without reference to units. Units are only necessary to assign a number. The fact that we disagree is independent of our units, and in fact the disagreement, the way to transform from my measurement to yours, can be expressed in a unit-independent way. The statement "acceleration is absolute" is again a shorthand for the fact that, once we all agree on units, we also agree on the state of acceleration (again provided we are in inertial frames). Furthermore, you can look at your own frame without regard to anything else in the universe and say "I am accelerating". You can't do that with velocity. The statement "I have velocity" has meaning only in reference to a chosen coordinate system. - Randy |
