at 0:53 did you mean atom or nucleus is mostly empty space ?

There is an error present in the first section - it says something about the nucleus being mostly empty space with a concentrated mass in a small region called the nucleus. It should be saying atom is mostly empty space not nucleus?

I just finished my paper 2 for OCR A, feeling really confident, couldn't have done it without you!!

probably the best paced physics channel, all the others are either so slow you fall asleep or so fast you miss everything before you even processed it

Love this guy so much, thank you for making my revision so much better!

what software do you use? it looks pretty good for notetaking

Hi, firstly I want to say thank you for all the amazing videos you put out, they are really useful. I'm just curious to the absence of binding energy and E=mc^2 stuff in this summary video?

Awesome concepts!! Explained welll !!, Thanks !

Hi, is the size of the nucleus you calculated not the distance of closest approach since 'r' in coulombs law is the distance between the centres? @zphysics

Hi Z, why does mass of proton ~ mass of neutron mean that the mass of a nucleon is proportional to nucleon number?

Shouldn't anti electron neutrino be emitted instead of electron neutrino? So that the lepton number stays at 0 for both LHS RHS of the equation

hi at 5:26 how does that value of d give an estimate for the size of the nucleus isn't d the seperation?

I’m 14:06 shouldn’t the force between 0.5fm and 3fm be repulsive and below 0.5fm it should be attractive?

Hi, I was confused about the part where you worked out the size of the nucleus. In the electric potential energy equation isn't r the separation between the 2 particles?

Questions:
-when would you use atomic mass unit
-how do you use it
-is the radius constant 1.2fm required to be remembered (and is it the same for every element?)

hi, just wondering if the classification of hadrons and leptons is something that can be in a large mark question or whether it is more just understanding examples of hadrons and leptons. Is the idea of strange quarks important too?

hello sir does the weak nuclear force apply to all hadrons and leptons? or just baryons and leptons?

In my formula sheet my electric potential is Q/(4πεr) but you’ve put Qq/(4πεr). Is that right?

how can we make our own animation video?

can these videos be applied well to the AQA specification?
