Atomic Mass

W HY M ASS AND N OT W eight-spot ? Some textbooks and other sources use the term atomic oppression instead of atomic concourse. The first of these is not as execute as the second, which explains why atomic hand was chosen as the subject of this essay. Indeed, the use of atomic heaviness today nurture reflects the fact that scientists in the past used that expression and enunciate of weighing atoms. though weigh is used as a verb in this essay, this is only because it is less cumbersome than quantity the muss of. (In addition, atomic weight may be mentioned when discussing studies by scientists of the ordinal century, who applied that term rather than atomic mass.)

Though the two ar relatively convertible on Earth, they are actually quite an different.

(Of course it would make no to a greater limit sense to measure atoms in pounds or kilograms than to measure the pretension of a hair in light-years; but pounds and kilograms are the close to familiar units of weight and mass respectively.) Weight is a measure of force affected by Earths gravitational pull. Therefore a persons weight varies a ccording to gravity, and would be different ! if measured on the Moon, whereas mass is the same throughout the universe. Its invariability makes mass pet to weight as a parameter of scientific measure. P UTTING AN A TOMS S IZE AND M ASS IN C ONTEXT Mass does not necessarily relate to size of it, though there is enough of a loose correlation that more than ofttimes than not, we can say that an item of truly(prenominal) small size will have very small mass.
