Strong Nuclear Force

057 - Strong Nuclear Force

In this video Paul Andersen explains how the strong nuclear force holds the nucleus together in spite of repulsive electrostatic charges acting on the nucleons. Mesons exchanged between nucleons keep the nucleus intact and gluons exchanged between the quarks achieve the same goal within the nucleons. The strong nuclear force accounts for the nuclear binding force in all atoms.

you taught me more in 4 minutes than my physics teacher could in 3 weeks. thanks!!!

[MatthewParkin-tylr]

This dude is a GOAT! He's helped my understanding of science explode throughout my high school and college career! Thanks Mr. Bozeman! You're the freakin man!

[siavash]

He's such an amazing teacher. He has great knowledge and even better explaining abilities. His IRL students are really lucky. This is a perfect teacher combination in my opinion and I'd been lucky to have a few of these teacher in my secondary education years.

3:49 - Its probably miss-stated that once a lot of nucleons get into the nucleus, that the strong forces are "not great enoguh".
They are great enough, but the nucleus gets bigger than the range of the strong forces.

Whenever I’m reading science for pleasure or studying for university, or just curious and don’t understand something, I get so excited when I search the topic and your videos show up! You are clear, comprehensive, and succint. Love your stuff!

These videos are saving my life in IPC. I'm in the eighth grade learning high school level courses and I think my teacher thinks we ARE in high school, meaning that I don't learn very good in the class. These are life savers, THANKS😊

I feel that you forgot to state that the strong nuclear force actually becomes a repulsive force at incredibly small distances and is why nucleons don't just collapse together to a single point.

I found this very helpful. I know it's extremely ambitious, but I would like to see a video which explains how quarks, gluons, and masons are involved in nuclear decay, and what their involvement is with the formation of beta decay or electron capture, and the production of neutrinos.

This vid was a water shed moment for so much.

[Baneslayer]

Great explanation, thank you! Simple and easy to understand.

[MindfulBytes]

Thank you Mr.Andersen for the wonderful video, it cleared a lot of my doubts. I was reading my text book and was having a hard time trying to understand how the strong force operates and how it is able to hold the components of the atoms together and why the average binding energy per nucleon decreased after iron. Your explanation was so precise and simple, that i have now understood this concept very well and my doubts are cleared.

[derrickmiller]

I've seen a thousand videos and you finally just simplified this for me

[stuartlunsford]

Excellent explanation giving some why to the forces. Thank you.

[BealsScience]

So I’m sitting here drinking coffee by the fire and researching how I can make a spinthariscope to show students radioactive decay with their own eyes and I stumble upon your video. Your explanation is brilliant! Simple, thorough and perfectly delivered! Thank you!
...now, back to my spinthariscope blueprints...

[akshaygupta]

Thankew Anderson sir I'm a std 12 student from India and no teacher was able to explain me from last two years.Thank you very much.

Most helpful video on this of a dozen I've just watched. So perhaps these statements are true.
1) It is the strong force within the nucleons that provides the strong force of the atom's nucleus.
Q: Do we know where in the nucleus the strong force originates, from WITHIN or from BETWEEN the nucleons?
2) When fusion releases binding energy, the amount of energy released has a correspondence with *excess* strong force.
3) The fusion that creates a nucleus releases binding energy when the full amount of the combined strong force of each of the individual nucleons is no longer needed 1) to hold each individual nucleon together, and 2) to stabilize the nucleus up to some level. This release of energy occurs because the strong force from within each nucleon is now overlapping to both 1) partially hold together its neighboring nucleons, and 2) hold together the nucleus, to some level of stability. So some portion of the energy of the nucleon strong force that is no longer needed (because some of its "territory" is being covered by the strong force of one or more other nucleons), is released (as heat energy).

[michaelmuller]

That was helpfull, I now know why iron is the turning point from fission to fussion if I understood correctly.

[superSHION]

Your videos are easy to understand, Subscribed!

[PoeticEquation]

And this totally explains why Iron (Fe) of all elements is so susceptible to magnets. Down to a molecular level magnets are metals that in a way have an electromagnet decay kind of like heavier elements that have so many more protons that decay and bleed radiation instead.

[sonamprasad]

thank you so much sir, you've helped me so much i could'nt understand it on my own, It is a great video.
