What do you weigh nzdating
And by the way, how did you manage to isolate a single atom in the first place?A moment's thought shows you can't weigh an atom on a traditional scale. Thomson and improved incrementally over the past century, it works like this: First, physicists "ionize" a gas of atoms by firing a beam of particles at the gas, which either adds electrons to the atoms in it or knocks a few of their electrons off, depending on the type of particle beam used.The mass of a body is a measure of how much matter it contains. If you shake an object like a stone in your hand, you would notice that it takes a push to get it moving, and another push to stop it again.If the stone is at rest, it wants to remain at rest.
We often use the terms "mass" and "weight" interchangeably in our daily speech, but to an astronomer or a physicist they are completely different things.Both of these fields exert a force on the ions, and the strengths of the two forces are proportional to the ions' charge (neutral atoms don't feel the forces).The electric force causes the ions to change speed, while the magnetic force bends their path.How muscular a person is, bone density, where they carry weight, and genetics should all be figured into estimates of their ideal weight.But the most common measurement, Body Mass Index or BMI, doesn't take any of this into account.
