The Standard Model of Particle Physics - A Level Physics

This video introduces the Standard Model of Particle Physics for A Level Physics.

It's a long video! But this shows the fundamental particles as we know them (in 2016) and the force carriers known as Bosons. The Standard Model of Physics currently consists of 17 particles. There are 5 bosons (4 plus the Higgs boson), 6 leptons and 6 quarks. Quarks can form baryons (3 quarks) and mesons (2 quarks). Baryons and mesons are types of hadrons.

Thanks for watching,

Lewis

This video is recommended for anyone studying A Level Physics in the following exam boards:
AQA

This kind of material needs to be taught in a very understanding and comprehensive way. Many college professors, like mine, fail to get the concepts across or go to fast to teach to the masses. You sir, have made it very simple. Thank you!

4:28 I'm pretty sure the quarks are not kept together by the weak force. They are kept together by the strong force, the weak is responsible for radioactive decay

[ArrowProds]

Damn, Lego's quite versatile. Very straightforward and practical explanation, while being both simple and adequately detailed. Thanks for explaining what my physics teacher couldn't reasonably.

[Catsithe]

I can’t believe that this information was just a google away. My entire perception of everything has changed - mind blown!

[saraha.k.]

love the neat representation done by the legos! it's soo much more organised now, thanks!

Quarks are bound together by the strong interaction only. Quarks are constantly changing color by exchanging glouns. You can imagine the bond as a flux tube. The potential energy between quarks grows the more you try to pull them apart, forming another quark pair once the flux tube breaks.

Weak interactions are a million times weaker than the strong interaction and are not responsible for the binding of quarks.

Full complete standard model and thank you very much man.

[adriancoronel]

VERY GOOD EXPLANATION, I love it phisical, leptons, fermions AND bosons, excelente, greetings from México.

[sehrisha]

OMG This Video is Soo helpful for edexcel IAL A2 physics
Thank you so much .. i have tried so many videos ... This video covered the basic concept so clearly and also covered the concept effectively..

[sonialee]

thanks for describing it so clearly and it helped me a lot to start studying the standard model! ❤️

[sabrinaislam]

Thank you so much for making make it so easier (I literally went into depression after going through the textbook)

[drsteviejasengnsangma]

6 years have passed you uploaded this video on atomic sub-particles but till today I find it the best(simplified) video on the topic.
very well done sir...

[caledoniatardivo]

Thank you so much for condensing this and making it easier to understand! :)

[pikchassis]

Oh my God I love you A physics level online!

[andyclark]

Thank you for your great lesson. With a visual interpretation it made it far easier to understand elementary particles. 👏

[darrenanimatic]

Are you telling me that elementary particles are like legos of the universe?

[zainabm]

I think generations are set for more than one reason . First, the historical line of discovering these quarks matters.Also, the 2 quarks of the same generation are more likely to be transferred from one to the other via weak interaction. While transferring a quark from one generation to a quark of another generation has a really small probability

[revanthelegend]

could there be lighter particles than gen.1 particles, simply because it scales up so much it could also scale down a lot as well. Although ....?

[Ward]

For AQA, what do we need to memorise? I know we are given stuff in the formula booklet but some questions require knowledge of like what quarks make up each particle… is there a checklist or something of particle physics that we should memorise?

[lrd]

Iv done my quarks in physics, got a test for it in 2 days time, yay.
