The Strong Nuclear Force - A Level Physics

This video explains the answer to the question: what holds the nucleus together? For A Level Physics.

Why do the positive protons stick together, and also why don't the electrons get attracted into the positive nucleus? It's all due to some special glu(ons) which produce the strong nuclear force.

Thanks for watching,

Lewis

You Missed That the Strong Nuclear Force Acts Between 3Fm and 0.5FM

[summitsparrow]

OMG this totally explained it for me! I never really understood neutrons until this video.

[thomasguest]

Thank you so much for uploading these videos, they really help me to revise!

[shakeelbltee]

really helpful videos. can you solve some questions on magnetic, electric and gravitational field aswell.

[adriancoronel]

Brillant !
Excelente explicación, thanks very much, greetings from México.

Well, Isn’t the gluons the force carrier that keeps the quarks together and a Meson called a ‘Pion’ which consist of an anti-color charge quark (In respect to the nearest nucleon’s quark color charge) which mediates the strong nuclear force?

[tyhayter]

Do the gluons come from the quarks of one proton to the other or are they spontaneously created upon the particles getting close to one another?

I read that gluons can interact with one another, how does that work m

great video! I had a question, what do u mean by the forces are in equilibrium at 5:06

Hi, congratulations on the channel. I have a question for you:
Are the protons and neutrons in the nucleus arranged in any particular way? Most models present the protons mixed with the neutrons in a random way, but don´t state which specific configuration actually occurs within the nucleus. For atoms like Lithium it may be easy to imagine a triangle with a neutron between each positive charge in a flat configuration, but as we add more particles it becomes much more difficult. I even imagined a scenario for larger atoms where the positive charges are all on the surface of the nucleus to be as close as possible to the electron cloud, and the neutrons would be more within that "sphere". They would help to dilute the repulsion between the positive charges, but also from there they would contribute to keep the protons inside the nucleus by counterbalancing more closely the action of the electrons from the outside and far more distant. Even considering the neutrality of the neutrons when we analyse them isolated, inside a region full of positive charges, these neutron pieces may present some "negativity" to that delimited space (the nucleus). What do you think about that? Are all these questions impossible to answer because of the uncertainty principle? Or we could at least try to simulate the various scenarios macroscopically or computationally? Thx

Strong force is carried by Mesons (quark-antiquark particle). Gluons binds the quarks inside the protons and neutrons.

[misseon]

How about mesons (pions) in residual strong force interactions between nucleons?

[VK-ilkv]

at 1:13, you said the force is inwards but then drew an arrow downards. why did you draw it like that and not narrow towards the nucleus?

[nirdeshkunwar]

you said wrong in 1:25 because when ever diresction changes, velocity also changes you must say speed remains the same or magnitude of the velocity stays the same.

Quantum Entangled Twisted Tubules:

Quantum Entangled Twisted Tubules: When we draw a sine wave on a blackboard, we are representing spatial curvature. Does a photon transfer spatial curvature from one location to another? Wrap a piece of wire around a pencil and it can produce a 3D coil of wire, much like a spring. When viewed from the side it can look like a two-dimensional sine wave. You could coil the wire with either a right-hand twist, or with a left-hand twist. Could Planck's Constant be proportional to the twist cycles. A photon with a higher frequency has more energy. (More spatial curvature). What if gluons are actually made up of these twisted tubes which become entangled with other tubes to produce quarks. (In the same way twisted electrical extension cords can become entangled.) Therefore, the gluons are actually a part of the quarks. Mesons are made up of two entangled tubes (Quarks/Gluons), while protons and neutrons would be made up of three entangled tubes. (Quarks/Gluons) The "Color Force" would be related to the XYZ coordinates (orientation) of entanglement. "Asymptotic Freedom", and "flux tubes" make sense based on this concept. Gravity is a result of a very small curvature imbalance within atoms. (This is why the force of gravity is so small.) Instead of attempting to explain matter as "particles", this concept attempts to explain matter more in the manner of our current understanding of the space-time curvature of gravity.

electron revolves around a circular orbit so the motion is an accelerated motion

[biosdaddy]

well i thought it was pion which is responsible for the strong force between protons and neutrons?

[GalaxiesWithJup]

Is this actually A level bc im 12 rn and im teaching myself abt this

[ellDiavolo]

I thought gluons hold together quarks not the protons

[guyguy]

Is it Gluon or pion because having a look it says pion in my book but apparently using a pion is a approximation and when looking at quarks its more accurate to say Gluon

[thrdel]

I understand that this explication is only a scientific model and it does sound better than "god holds them together.
Nevertheless, I find it hard to believe that this model can actually be tested. It may look great from the mathematical point of view but it kinda sound like we realized we have a problem and all of the sudden a new kind of force was born that explains it all . It had to be stronger than the electro-magnetic force so, shazam - strong force.
Same goes for the magic gluon, I looked up the definition of it and it goes like this :
" a hypothetical massless subatomic particle believed to transmit the force binding" !
So basically, even if this model is presented as a fact, it is merely a hypothetical possibility since we have nothing better for now, isn't it ?
