Both statements are incorrect. Mass is the amount of substance there inside the defined boundaries of your system. Mass is an intrinsic property, i.e. it is not dependend on anything outside the defined boundaries of your system. Weight is the force excerted by the mass inside the defined boundaries of your system on another object as the result of a constant accelarion. Weight is an extrinsic property, i.e. it depends on things outside the defined boundaries of your system. If we take you to be the defined system, it is reasonable to say that your weight is the force your mass excerts on the ground beneath you under the influence of the gravity. But if you are in an elevator that is in free fall, you don't excert that force and you are truely weightless. Your weight is actually the product of an accelleration and your mass. And since the gravity (an accelleration) could be different on different planets, your weight could be different there as well. > Jupiter is heavier > than Earth and Earth is heaver than Venus. Not necessarily true. Since weight (according to the dictionary heavier means "of more weight") depends on an object outside the system you can not say this without defining that extra object. And if you leave all objects outside your system out of the equation, all three planets are weightless. > I am heavier than most people > because I have a large mass (I am a Tall Fat Bustard).

Hardly relevant for the issue, unless we get to the densities that force electrons out of their orbitals into fission with the associated protons and only the "zero point" energy prevents the formation of a black hole.

I don't normally discuss this when I am sober nor do I tend to do it in English. ______________________________________________________________________ Get the mailserver that powers this list at http://www.coolfusion.com Archives: http://www.mail-archive.com/[email protected]/ Unsubscribe: http://www.houseoffusion.com/index.cfm?sidebar=lists
