      @@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!

    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.

    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]

    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.

      @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.
