E=mc2 questions?

[Dywyddyr]

I am not refuting anything

Wrong again.
More than once on this forum you have claimed that science is wrong.
And even in this thread you have claimed - repeatedly - that mass and weight are the same thing.

are you saying that lb, kg, kilo , is not a unit of weight?

Correct.
They're units of MASS.
You yourself have stated that weight is given in newtons.

 

[OnlyMe]

It should be moved to the cesspool now the trolls have ruined another good talking thread about E=mc2 etc. Maybe I should talk giant green lizards or something it would suit these people much more, they hate complicated topics.

Whatever you do, you should do it somewhere else!

This is my confusion, if i go the shop and ask for 1kg of apples, the shop assistance weighs them out, and 1kg is the weight, this is something people of earth observe.

So you are now saying that everyones life is lie, because you are not weighing the apples you are measuring their mass?

I am not refuting anything I am asking you why is this, why is it this way, why is not this way, it is you not understanding , are you saying that lb, kg, kilo , is not a unit of weight?

You can not have mass without weight, mass is the weight of an object by the imposed force of gravity. The constant that gives the constant mass which is the weight.

You say that G does not come into the calculation, that is wrong, the mass is the weight that is made by the gravitational constant?

He is not refuting anything people! Except of course common sense.

Are you trying to say that gravity is not a constant that is a constantly applied force to all matter?

And yet the mass of that 1 kg of Apples on Earth would weigh 160gms on the Moon. Same mass, different weight.

There should be no confusion. It has been explained to you that in 1G 1 kg of mass weighs "1 kg".

So you are now saying that everyones life is lie, because you are not weighing the apples you are measuring their mass?

From post #5 "Mass is not the same thing as weight, even though we commonly calculate an object's mass by measuring its weight".
From post #10 "This may be true in every day usage but ONLY because every day stuff takes such measurements as Earth based for granted".
From post #17 "Weight is a localized measurement of the mass associated with an object.., which is dependent on where in a gravitational field you weigh the object".
Etc.

What? 1kg is the mass on earth like Dy just said, its not the same mass, it is the same density and shape, I do not get it, make your minds up

dy-''correct.
They're units of MASS.
You yourself have stated that weight is given in newtons.''

cry , omg,''1 kg of mass weighs "1 kg".''so the weight is exactly the same has the mass which is the same thing like I said.

What the hell has that question got to do with the lie I just proved you are telling?
Again, you said......

So, are you still going to deny you are not refuting anything?
Or is this just the rantings of a troll?​

You obviously missed (or decided to ignore) the fact that I put the weight of "1 kg" in scare quotes.
And also missed, or ignored, the fact that I also stated "in 1 G".
Elsewhere a 1 mass of 1 kg will NOT weigh "1 kg".

1 kg weighs 1 kg ONLY under 1 G.

Mass is not weight.
Weight is not mass.

Because g has to be in it because that is the constant applied force that is always there applied to any object on Earth, so yes I suppose I should of not said wrong, and worded it better, but either way it is a good question to ask.

Mass is not weight.
Weight is not mass.

So you decided or science decided that what in normal life we call weight, such has grams, ounces, kilos, you would change the context and call that mass, and then you would define weight by Newtons just to confuse the populus of the planet?

 

[Russ_Watters]

Correct.
They're units of MASS.
You yourself have stated that weight is given in newtons.

Lb is force. But to expand, "weight" is just a specific type of force. So I think it would be better to just say N and lb are units of force. That way you don't accidentally imply that tension and weight (for example) might need different units.

Wrong again.
No one "decided".
That's how it turned out once it was discovered that mass is a constant while weight isn't.
It doesn't "confuse the populus (sic)" since it doesn't impinge on them in day to day life - as has been explained.
Anyone who actually (genuinely [1]) learns science is taught the difference and when and where that difference applies.

1 I.e. not the way YOU "learn" it.

 

[Russ_Watters]

Have you checked out his other threads?
You'll find one or two in alternative, a few in pseudoscience and a few in cesspool.

Oh, I know, but it still amazes me. It takes a special kind of arrogance to continue to believe in himself, while demonstrating truly SPECTACULAR ignorance.

Not quite.
lb is mass. lbf is force.

I get this, but the part im trying to express is that you have mass as kg etc, and in the normal world this is weight that is measured by the force applied by gravity of an object on a set of scales, so the mass is always equal to the weight, for example I have 9.81n I know i have 1kg, I can not see how there is any real difference, to me I see the exact same thing.

No, you actually are telling untruths, as you have been doing continually in this and many other threads. It's that simple.
