Hey Factful thank you so much for the support and comment (really helps the vids get seen)! Hope all your work is going well 🙌

[@RodsterLIVE]

Agreed

@@Cognitoedu Amazing video! Clear, simple, and easy to understand. What I'm wondering now is: what happens to the "daughter" atoms that result from the neutron hitting the original atom? Are the daughter atoms able to further be split into more atoms if a neutron hits them (although that wouldn't make sense because they are already stable)? Will they keep gaining neutrons until they are unstable again and thus, make it so they can be split again? Or do they simply not matter after the atom is split? I'm also wondering where the neutron that splits the original atom in half comes from in the first place. Thanks!

Exactly

Agreed

[@fridah8523]

Amazing explanation. 10/10. Perfect. Concise. Clear. Would recommend for every GCSE physics student.

[@qwertyproductions4109]

Wow! I am literally awed by the animation, graphics, handwriting and most importantly, the explanation of this video. Can u tell me how you make the animations and stuff please?

No.

Sorry for the very late reply - these were made using sketchpad on an ipad and imovie. That method no longer works so we now use mainly After Effects and Procreate :)

Great, clear explanation. I am using this with my physics students as an introductory video (great for distance learning during COVID-19). I wonder if comments ! with lots of exclamation ! points ! help ! the algorithms? !!!!

Another really nicely produced video and well presented. Avoid saying nuclei for a single nucleus - try to avoid doing this in the exam. Much of the energy is also in the kinetic energy of the products not just gamma rays.

[@Jana-wp7ey]

Why not nuclei

[@dtr3197]

​@@Jana-wp7ey when you're answering a question on nuclear fission you need to be clear about a single nucleus splitting to form two daughter nuclei. If you use the wrong word you might not be awarded the mark as a CON (contradiction)

[@stustjohn]

Your videos are great!! I am a Physics teacher and have been using them for my classes, as part of their work during Lockdown 2020. The accuracy of information and quality of diagrams is nearly always 100%. However, every time I listen to this particular video I keep hearing the phrase "a nuclei" and it grates on me. I know it's a tiny thing (pun intended ;-) ) but it just bugs me, and I can't help it! [Singular = nucleus; plural = nuclei]

[@Cognitoedu]

Ah cheers for that, we’ll make sure to fix it in any re-releases or future vids!

[@uzma191]

So just to confirm , where he started off is it the splitting up of a nucleus or a nuclei ?

[@charlessota2323]

Thank you for such simplicity

[@carlmetcalf5629]

Fantastic graphics -clear simple explanation, thanks. A lot better than many of the you tube videos I have looked at. I am thinking of linking this video to my class during lockdown if that is ok with you? Couple of minor points - much of the energy released is kinetic energy of the products - not just 'in the form gamma radiation'. Also for AQA - our exam board - they emphasise large amount of energy from a small amount of fuel (energy density) and don't credit - large amount of energy by itself.

[@Cognitoedu]

Hi Carl cheers for those points - we’ll note them down and incorporate them in any future updates. Please feel free to link the video to your students!

[@carlmetcalf5629]

@Liang Aidan sorry - only just seen this - a slow neutron is more likely to absorbed - the moderator is there to reduce the kinetic energy of the neutrons so that they are more likely to be absorbed and cause further fissions.

[@maherischlong]

2:21 yes 🙂

[@ja_adam_]

So how in reality do you actually have a nucleus and put it into an atom? You cant see or grab them? Please explain

[@TBSCDood]

from around 1.10 it basically explains how a nuclear weapon is made, uranium235 which has neutrons fired to it, creating an ultimate fission that spreads like a very diameter
