Is the weight of a person the same as the volume of the person?

..also they're measured in different units.\nVolume is measured in cubic units (m^3, ft^3 etc), whereas  weight is measured in units of Force (Newtons, or foot pounds)\n\nYour volume is fixed (unless you have a large dinner) whereas your weight varies depending on your altitude. You actually weight less at the top of Everest than you do at sea level.\n\nIt should also be noted that weight and mass are different.

I think the equation W = m x g (W = weight; m = mass; g = acceleration due to gravity) might address your question.\n\nStating they are interchangeable might be misleading if the statement is not qualified by your textbook. The qualification is that when we are measuring objects from an earth reference point, for all intents and purposes, the weight of an object is proportional to its content (i.e., mass). In mathematical terms, the assumption would be, W = m * 1. \n\nHowever, if we are measuring objects in places other than from an earth reference point, then weight and mass are not interchangeable. For example, the force of gravity on the moon is less than on earth. So as an example, the equation for weight on the moon could be, W = m * .5. With this equation, the weight of an object on the moon is less than its weight on the earth. Here is a math example to illustrate:\n\nObject (Mass) = 100 Kg\ng(Earth) =  1 \ng(Moon) = .5\n\nW(Earth) = 100 x 1\n              = 100 Kg (Object's weight on earth)\n\nW(Moon) = 100 x .5\n              = 50 Kg (Object's weight on moon)\n\nWikipedia might explain the notion of interchange between weight and mass better:\n\nhttp://en.wikipedia.org/wiki/Weight#Weight_and_mass

Yes it would weigh the same. The air contained in the can would only change the weight if it was pressurized. Otherwise the air pressure would be consistant with the atmospheric pressure in the room.\n\nSmashing the can would only change the weight of the can if you smashed it so much that you pulversied it into oblivion

Yes, the greater height and lean weight of a person effects almost all organs in a similar manner.  There are also individiual variations.  However, a 400 pd obese person wont have a small intestine twice the size of a 2oo pd lean person.

kg is a measure of mass and not weight.  Though, it often gets confused.  The mass of a person does not change unless he consume something or eject something from his body.  His mass would not change wether the elevator goes up, down or sideways.  Depends on what the question is looking for.  The most accurate answer should be: \n\n65kg x (9.81+2)m/s^2 = 767.65 N (newton).\n\nThe old weight of the person is:\n\n65kg x 9.81 m/s^2 =637.65 N\n\nIt would be ridiculous if the question asked for the weight in pounds, but here is a conversion:\n\n767.65 N x 0.2248 N/lbf = 172.56 lbf (as in pound-force, which is different from pound-mas (lbm), the common concept of measure in weight most of us are familiar with, 1 lbf = 1 lbm x 32.2 ft/s^2 )\n\nNow that I have confused everyone.  I just wonder if a physics teacher can explain it any better? lol.\n\n\nXR

Yes, absolutely!  I am same height/weight, as long as it's muscle weight, it's fine!!  Most people don't believe it when I tell them how much I weigh, they think it's lower!!

density is mass divided by volume - so if you know the volume and the density, then you multiply them to get the mass  (which is synonomous with weight)

That depends on the individual and how much muscle mass they have.  For instance, Vin Diesel has a greater percentage of muscle weight than, say, Clay Aiken. *nods*

oldhippypaul is right, the correct statement is "both corks are subject to the same buoyant force". The explanation is that, if they´re identical,they weigh the same. Since there in balance (i.e., there not sinking or emerging) the bouyant force must equal thre weight and, therefore is fhe same.

Logic you say? Logic does one no good if you start from ignorance. Fat people have more mass than thin folks - if this mass is rapidly converted into radiant energy (e=mc2), the resulting explosion of a fat person will be larger than a thin person. When you talk about fat people being slow you're referring to the biological processes within their bodies - too much fat drags on their metabolism. This has nothing to do with mass energy equivalence.

Weight is a unit measure of gravitational force.

not at all, the material weight is just taking different forms, a person is a composition of something already here, there is not heavier planet.\n\n:> peace\n.

No the density would be the same. The sample size does not affect the density. The Volume and Mass grow at proportional rates, so it doesn't affect density.

There is no equation to convert mass into weight, because it all depends on the density of the material. Even something as simple as a liter of water won't always weigh the same each time, because the temperature will change its density. Hot water is less dense than cold water, therefore the same volume of hot and cold waters don't weigh the same. Another example. Take a gallon of flour and weigh it. Now fill that same gallon container with sand and weigh it. It will not weigh the same because sand is denser than flour. \nThe bottom line is, you can't convert mass into weight because there are too many variables for one equation to solve all problems.

Mass is a fundamental quality. No matter where something is, it has the same mass. Weight, on the other hand, is the force that gravity exerts on the mass. Though in standard units we measure both in pounds, technically mass is measured in pounds mass, while weight is measured in pounds force. In SI units, mass is measured in grams, and weight in newtons.\n\nTo answer your question, weight will change with distance from the earth's center. Mass will not.

there are different formulas for volume.
