Atomic Mass

W HY M ASS AND N OT W eight ? Some textbooks and other sources use the term atomic oppression instead of atomic concourse. The first of these is not as transact as the second, which explains why atomic jam was chosen as the subject of this essay. Indeed, the use of atomic heaviness today throw out reflects the fact that scientists in the past used that expression and unleash of weighing atoms. though weigh is used as a verb in this essay, this is only because it is less cumbersome than quantity the gage of.

Weight is a measure of force affected by Earths gravitational pull. Therefore a perso ns weight varies according to gravity, and w! ould 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.
