Where does the weight go?

You breathe it out as carbon dioxide.  You also probably lost some water weight through evaporation and urination.

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

Due to sublimation, it will weigh slightly less. However, in a closed system (say you sealed the cup in an airtight box and weighed that before and after the ice melted) there would be 0 change in mass due to conservation of mass/energy.

Tell them that the mass is the actual ammount of stuff(matter) in a given object.  Weight is the force of gravity pulling on the stuff (mass or object).  The gravity is caused by the ammount of mass in the other object.  So on earth it has a constant mass so the ammount gravity on an object is constant.  Therefore on earth we can measure the mass of an object using its weight.

well make sure that you take in to account anything that might be holding what you are weighting for example say u are weighing water the water is being held in say a beaker....you have to subtract the weight of the beaker from the weight of the water to get just the weight of the water also be sure about that fact that when nothing is on it that it lines up to zero (because nothing is on it.)

It weighs the amount that the air inside it weighs.

Weight is a force, but when something is weighed you actually measure it's mass assuming you are in an environment in which the force of gravity is constant (i.e., you're at a fixed location <radius from the center> on a planet or massive planetary mass).\n\nof course, one's mass can be approximated by W=mg at fixed radii from such planetary masses (like the earth, a massive asteroid, a superdense star, whatever...) if the force of gravity, g, is known at that radius.\n\nThere are 2 possible variables here - mass and the force of gravity.  Which one do you know?  usually an approximation for g is given.  Which one do you measure, then...that would be mass.

We define weight on Earth in reference to the Earth's gravitational field.  Having the Sun go away wouldn't change your weight on Earth.

The previous answerer has the right idea but the wrong details.\n\nThe four parts should weigh 1, 3, 9 and 27 pounds.  The logic is that the desired weight is written in "balanced ternary" notation, where the values of the digit positions are 1, 3, 9, 27, 81, . . . (that's "ternary"), but the allowed digit values instead of being 0, 1, 2 (that's regular ternary) are -1, 0, 1 (that's balanced ternary).  Then the digit values for any desired total weight written down in balanced ternary tell you whether the weight for that column is to go in one pan, go in the other pan, or stay on the floor.

Weight is a force.  The National Institute of Science and Technologiy defines it here as such.\nhttp://physics.nist.gov/Pubs/SP811/sec08.html\n\nA force is acceleration times mass.  Weight is the accleration due to gravity times mass.  On the Earth's surface, this is approximately:\n\nWeight = Mass x 9.8 meters/second^2\n\nFor a accurate conversion, you would need to use the acceleration due gravity minus the accelration due to centrifugal force at your exact location.  \n\nThis is why physicists more commonly use mass than weight to describe an object.

we have F= G*M*m/r^2  and F=weight\n\nwhen M=M and r= r/2 then F=G*M*m/ (r/2)^2\n\ntherefore F(new)= 4*F and hence new weight is 4 times.\n\nthis is due to change in the value of g(acceleration due to gravity)\n\nsince F=mg= G*M*m/r^2   and hence only g is effected\n\nand hence weight also changes mass remainig same.

All is clear once you understand the difference between mass and weight.\n\nIf you are not sure, look here:

An object has mass regardless of gravity.  Gravity gives us 'weight' by placing force on the mass.\n\nSo, strictly speaking, an object's "mass" is a measure of how much matter it contains.  An object's "weight" is a measure of gravity's effect on that object.\n\nSo an object's mass doesn't change if it is on a different planet, but its weight will.

Weight is the amount of force on an object and mass is the amount of matter in that object
