what does weight times density equal?
Simple thread I know, but I couldn't find a straightfoward answer online.

I haven't, but surely it must equal something?berkeman said:Doesn't ring a bell. Where have you seen it used?
bonjour said:I haven't, but surely it must equal something?
berkeman said:Please don't call me Shirley.
And no, it doesn't have to be anything special or real. Just look at the units...
bonjour said:
Ok, what is the difference between volume and mass?
Apologides for not starting a new thread, I'm sure you agree it would just be a waste of space.
berkeman said:Mass/Volume = Density. But surely you know that already...
Why these specific questions? Are you studying something that is bringing them up?
bonjour said:I know what I'm told.
What is the difference between mass and volume?
My knowledge on physics isn't extensive. Please forgive me. If you believe I am wasting your time, I apologise, it is DEFINATELY not my intention to do so, and I strongly apologise if I have offended you in any way. I am simply trying to make sense.
berkeman said:No offense taken. I guess you can say that volume and mass are two properties of an object. The volume and mass of an object are related to each other via another property of the object, which is its density. I'm not sure that there's much more to it than that.
Are you familiar with the website www.wikipedia.org?[/url] It has useful pages on many introductory subjects. It's less reliable for more advanced subjects, but the intro subjects are generally treated pretty well. The wewbsite [url]www.HowStuffWorks.com[/URL] is also good for many subjects.[/QUOTE]
I cannot thank you enough for the time you are giving me. i am extremely grateful. I have been off and on wiki all evening. It states things but does not explain questions I have or destroy my confusion. to put it another way, I cannot delve further with wiki on specific issues that arise from my (mis)understanding.
The biggest apology here if you do get offended, but I am being honest and I believe you deserve honesty, rather than a patronisation.
It appears to me you haven't really described the differences between mass and volume.
you've described the similarity.
But what is the fundamental difference between volume and mass? What makes mass...mass and not volume?
A volume is a delimited region in a 3 dimensional space. For example a box and the space in it.But what is the fundamental difference between volume and mass? What makes mass...mass and not volume?
Does everything hold mass?fluidistic said:A volume is a delimited region in a 3 dimensional space. For example a box and the space in it.
The mass is a property of a particle/object, etc. So what makes mass is the existence of particles/bodies. ( I believe so!)
Still confused? I find both concept pretty easy to understand, even if I can't define them well. (Like time and energy).
No. Why would you think so?bonjour said:So is mass a metaphysical concept?
What about dark energy?dacruick said:no. not everything has mass. All matter does though.
Well, we don't know what it is yet, but if it's energy, it won't have mass.bonjour said:What about dark energy?
Wouldn't that mean e=mc2 is wrong then?DaveC426913 said:Well, we don't know what it is yet, but if it's energy, it won't have mass.
No.bonjour said:Wouldn't that mean e=mc2 is wrong then?
I think I understand, energy does not consist of mass and the speed of light...right?DaveC426913 said:No.
Einstein's equation says that mass and energy are equivalent, not that they are the same thing.
If you took a mass M and converted it to energy, the amount of energy you would get is Mc^2.

bonjour said:Also this suggests to me, that anti matter, dark matter, negative matter are the same things. Is this the thought of the science community at present? Or do people consider them to be completely different things?

bonjour said:Dark matter is what I consider(ed) to be negative matter as it would be equivalent to having none/negative mass
Well if its negative in mass, it's negative in matter. Obvious of course. This weirdly is reminiscent of my earlier post.DaveC426913 said:OK, now you understand that darkmatter indeed has mass. That's its defining property. What we don't understand is why we can't see it.

well it has dark mass. But I say negative mass as I feel it's more concisive.berkeman said:Dark matter does not have negative mass. It has positive mass.

Can you elaborate?Phrak said:Urm. E=mc^2 is not a conversion equation but an equivalence. If it where, it would be E+mc^2=0 though there are endless authors that do this...

The formula for calculating weight x density is weight (in grams) x density (in grams per cubic centimeter).
Yes, weight x density can be used to measure the mass of an object. Mass is a measure of the amount of matter in an object, and weight x density is a way to calculate the amount of matter based on its weight and density.
Weight x density is directly related to the buoyancy of an object. If the weight of an object is less than the weight of the fluid it is placed in (based on its density), the object will float. If the weight of an object is greater than the weight of the fluid, it will sink.
Yes, weight x density can be affected by the temperature of a substance. As temperature increases, the density of a substance may decrease, resulting in a change in weight x density.
Weight x density is used in a variety of real-world applications, such as determining the weight of liquids or solids, calculating the weight of objects in different environments (such as underwater), and in industries such as construction, engineering, and chemistry.
