forsaken Posted November 15, 2007 Share Posted November 15, 2007 In modern usage in the field of mechanics, weight and mass are fundamentally different quantities: mass is an intrinsic property of matter, whereas weight is a force that results from the action of gravity on matter. However, the recognition of this difference is, historically, a relatively recent development ÃÆââââ¬Å¡Ã¬Ã¢ââ¬Ãâ and in many everyday situations the word "weight" continues to be used when "mass" is meant. For example, we say that an object "weighs one kilogram"; that kilogram is a unit of mass. I contend that we are both atheists. I just believe in one fewer god than you do. When you understand why you dismiss all the other possible gods, you will understand why I dismiss yours." Link to comment Share on other sites More sharing options...

Jaziek Posted November 15, 2007 Share Posted November 15, 2007 reading through this thread.. i'm hoping that all we're having is some breakdown of communication and that the education system hasnt effed up that badly. one of my physics teachers is a moron and i still manage to understand it.

Korla Posted November 15, 2007 Share Posted November 15, 2007 apparently nobody on this thread knows that mass=weight/volume, something that should have been taught in 6th grade :-k LOL! EPIC FAIL. I see the problem in communication here, you are an idiot. Lol, nicely put Indy. Since I have to add something to this post... Mass is actually m0/sqrt(1+1/(v^2/c^2)) where v is your relative speed, c is the speed of light in vacuum and m0 is your mass while rested.

BlueTear Posted November 15, 2007 Share Posted November 15, 2007 apparently nobody on this thread knows that mass=weight/volume, something that should have been taught in 6th grade :-kSo since weight depends on, say, what planet you happen to be standing on, if I were to travel to Mars, my mass would dimish? But since mass and energy are really two aspects of the same thing, and energy is never destroyed only transformed, that mass would have to go somewhere... Hmz... Into, for example, my speed!

The relationship, as has been stated a few times in this thread, is that 1kg = 9,8N since the gravitational force is roughly 9,8 m/s^2 That's what's way off in the quoted text.

Potter_Pkr Posted November 15, 2007 Share Posted November 15, 2007 Perhaps I'm wrong, but I thought that when you measured something in Newtons, it was how much gravitational force you had on the ground. Then thats why your mass is still the same on whatever planet your on but your Newtons may become smaller if you were on the moon....or larger if you were on Jupiter.

It's 6 kilos not 60. Which, in my error, is more like 13 pounds. Damnit. To the metric system America! The best thing to do is keep your imperial and metric measurements separate. Don't measure your weight in pounds if you are going to use it in a formula, which only uses metric (SI) units. Only use imperial to compare with other imperial measurements. The best thing to do is not to try to convert one into the other, because you end up multiplying with awkward decimal numbers, so if you need to, measure yourself twice, one in metric and one in imperial. If you have a weight scale which only measures in imperial, it's too old and impractical in science. If it measures only in metric, it's too impractical for domestic use, unless it is only used in scientific work. If it simultaneously measures metric and imperial (but not by conversion from one to the other), use it. Avoid conversion at all costs. And Potter_Pkr is right. You weight is a force exerted on the surface of the object you are standing on (In the vast majority of cases, planet Earth). Since it is a force, it is measured in Newtons. Newtons are defined as 'The force required to accelerate an object of mass 1kg at a rate of 1m/s^2.' They are linked, but there are dodgy conversions from N to kg, so again I suggest that you weigh the object again for weight and mass separately. There is no harm in repeat experimentation. ~ W ~ Link to comment Share on other sites More sharing options...

The poor guy is trying to understand the difference between mass and weight, and you are explaining him relativistic effects of high speed to mass?

Animaslayer Posted November 16, 2007 Share Posted November 16, 2007 Newton or N is the force of gravity pulling down on something IE and apple is 5N or 5 Newtons ( no i didnt weight it just exampling) Dragon Drops: Platelegs x9, Med Helms x7, Plateskirts x4, Shield Left Half x3, At least 75+ Boots!, Hatchets x5, Ruined Shard x1, Solo Claws x2, Dragon 2Hander x1, Spear x2Whip x27, Dark Bows x9, Draconic Visage x1 <- do that when you see me :P Link to comment Share on other sites More sharing options...
llamster Posted November 17, 2007 Share Posted November 17, 2007 Point is, I've lived for 10 years of my life In Europe. I have NEVER heard someone say "Oh...I weight 80 Newtons, how about you?" in Europe. SI doesn't mean European. Ah, this reminds me about the noob on the Runescape forums who was upset with the quest "Cold War" because apparently his grandparents died in the war. :wall: Link to comment Share on other sites More sharing options...
Lionheart_0 Posted November 17, 2007 Share Posted November 17, 2007 Weight=force mass=the actual ammount there. When you step on a scale, it shows you your mass based on your weight (your mass affected by the gravity of earth). But people always say it's their "weight" when in reality it is their mass that they know. So when a persons say they weigh X kg/lbs, they are not wrong, its just they are using the wrong word, they should say their mass is. Doesn't really matter though, its one of those things that unless your talking about science, its really no use. Sig by IkuraiYour Guide to Posting!

r2d2 Posted November 18, 2007 Share Posted November 18, 2007 when you step on a scale, you measure your weight, NOT your mass. It is physically impossible to find your mass...
