How many newtons are in an object?

Answer 1

Newtons????

Or neutrons?

In most atoms, the number of neutrons is the same as the number of protons.

Sometimes, an atom of, say carbon, has isotopes - atoms with different number of neutrons than the most commonly existing type of that element. C12 would have 12 neutrons, C14 would have 14. The charge doesn't change as neutrons have a neutral charge.

Answer 2

The weight of an object is typically measured in newtons. On Earth, the weight of an object is equal to the mass of the object multiplied by the acceleration due to gravity (approximately 9.81 m/s^2). So, the number of newtons in an object depends on its mass and the acceleration due to gravity in that specific location.

Answer 3

The number of neutrons in an atom can vary. We need to review a bit of atomic structure to get a handle on this, so let's dive in.

We know that a proton (which has a charge of +1) has about the same mass as a neutron (which has no charge). An electron (which has a charge of -1) is much, much less massive. When atoms form, protons and neutrons are bound together to create a nucleus. That's because protons cannot bind to protons by themselves and stay that way because like charges repel. (The presence of the neutrons allows nuclear binding energy to hold the protons and neutrons together.) Electrons form up in shells around the nucleus, and they make up what is called an electron cloud.

It is the number of protons in an atom that give it its chemical identity. For instance, all atoms with 26 protons in their nucleus are atoms of the element iron. Neutron counts within a bunch of iron atoms will vary, but the fact that there are 26 protons in an atom make an atom of the metal iron. But what about those neutrons?

The thing is, an atom can have a few less or a few more neutrons than another atoms of the same kind, as we mentioned. The term we use to speak to the differing neutron count from atom to atom is isotope. Different isotopes of a given element have different numbers of neutrons, and we simply have to examine a large number of atoms of each element to discover the neutron counts in the atoms. Some elements have only a couple of stable isotopes, and others have a handful. Still others have no stable isotopes at all.

The bottom line is that the number of neutrons in an atom of any given material will have to be determined by an investigator. Sometimes we are told the number in an "indirect" way by use of nomenclature. In the case of iron, if we see iron-56, we are looking at the most abundant isotope of iron. Iron has, as we mentioned, 26 protons. If we are talking about iron-56, it has an atomic weight of 56, and 26 of those "weights" are protons. We can take 56 - 26 and get 30 for the number of protons in iron-56. In the case of iron-57, it 57 - 26 or 31 neutrons in it.

Neutron counts in an atom vary. And each element has several different isotopes, whether they are stable or not. Some isotopes were created in the physics laboratory (and we've made a whole lot, by the way). Pick any element you have any familiarity with and have a look at the different isotopes associated with that element. Attempt to get a feel for how the isotope thing works with that element. There are some surprises and some puzzles that any investigator will uncover. Guaranteed. You'll need to understand the basics of isotopes to understand chemistry. And don't even think of tackling nuclear physics without a working knowledge of isotopes. Links can be found below.

Answer 4

Newtons first law states that and object in motion will stay in motion in a straight line unless and outside force has acted upon it and that an object at rest will stay at rest unless and outside force has acted upon it.

Answer 5

9.8 newtons/kilogram. In other words, an object with a mass of 1 kilogram will weigh 9.8 newtons, an object with twice that mass will have twice the weight, etc.

The force of gravity is often expressed as an acceleration - 9.8 meters/second2. This is equivalent to newtons/kilogram.

Answer 6

Newtons are a measure of force, not weight.

Unless you are talking about fig newtons, newtons are a measure of force.

Weight is the force of exerted on a body with any given mass by gravity, so weight can be measured in Newtons.

To figure out the weight felt by the body this is the equation F= G Mm/R2, where M is the mass of body exerting the force, m is the mass of the body feeling the force, G is the gravitational constant, and R is the distance of the bodies from their respective centre of mass.

On Earth for example the weight equation is simplified to F = mg where in this case g is the acceleration by gravity (9.81 m/s2). So for a 100kg person the weight of such a person would be 98.1 N.

Answer 7

The force of gravity never stops, and there's no limit to how far it can reach.

So there's no such thing as "break" gravity. The best you can do is come up

with enough force to move the other way, opposite to the direction that

gravity is pulling you. You do that with your legs every time you walk up

some stairs. Some people call that "defying" gravity, but there's no defiance

involved. It's simply an application of vector addition with some forces.

The minimum force required in order to move opposite gravity ... and keep going ...

is the number of Newtons that's equal to the weight of the object you're trying

to move in the opposite direction. Anything less than that, and gravity wins.

Answer 9

A newton is equal to 1 kgms-2. The newton is the SI unit for force, and is a derived unit. It is equivalent to approximately 0.225 pounds-force.

Answer 10

Quoting the AnswerTip,

"the unit of force required to accelerate a mass of one kilogram one meter per second per second"
