Fusion, Fission, and Energy in Nuclear Equations - IB Physics

[@phosphor6531]

ive been searching around for how fusion works, and almost every video is just some 7th grade explanation, finally i found a video like this!

thanks i got a test in like 20 mins im cramming so hard lmao this was helpful

God bless people like him who don’t yap

[@AndyMasley]

I used a lot of video lectures when I was a student and got so frustrated when people took a lot of time in the videos yapping about unrelated stuff. Was a big motivation to try to avoid that

[@griefinnub3745]

This is such a good explanation with easy to understand visual presentations. Thanks a lot for this video!

[@manitverma4425]

good ib questions my man!

[@willnelson3167]

Not sure if I understand completely, but definitely helped a bit!

[@CompCode-Central]

This was amazing thanks so much

[@prathameshrumde2811]

Awesome lec sir

[@yushidos]

i dont understand example problem 2. The energy is being released, so why not add the released one with the energy after the decay to find the energy before the decay? Because the energy before the decay is before the energy was released

[@marcomori317]

fantastic! Thanks 🙏

at 0:43 you mentioned that " the binding energy is the energy individual nucleons have released in order to bond". i think that is incorrect. what you said is true for the binding energy per nucleon. binding energy is the energy that holds the nucleus together which is proportional to the mass defect. binding energy can also be defined as the minimum energy that is required to separate the nucleons. please correct me if im wrong

[@Music_Creativity_Science]

I think what the video creator also is trying to say is that the binding energy isn't in the form of a spring (an analogy), with energy waiting to be released. Then we wouldn't have any use of these nuclear reactions... just mass transforming to energy in the form of bindings. If I understand it right the binding energy is always released as kinetic energy among the new created particles/molecules, released thermal energy (heat), which is the principle of an atomic power plant (heat creating electricity). So you have to think in three steps, mass -> binding energy -> kinetic energy at atom level (heat), not just "stored" binding energy doing nothing.

[@doiklee6060]

Me too I dont get it if the mass defect is converted into binding energy to hold the protons and nucleons together, then the reaction shouldnt be releasing energy at all, which we would use to create electricty. I am so confused. Have you understood what is going on?

Few sites like this video describe why iron atoms are the dead end of star core fusion to produce heavier atoms.

thank you so much!! this was so helpful

Tbh ur not that good of a teacher but still u gave useful information(i think) its just thay u went very quickly and didn't explain in detail about some of ur steps but other then that ty for this vid

[@AndyMasley]

Appreciate the honesty brah mad respect

[@egghead3418]

@@AndyMasley ty fam I hope ur vids helped some poeple tho pls try to add even the tiniest bit of steps all wishes stay well sir

[@daiyankarim9137]

@@AndyMasley dont listen to that clown, your vids are the holy grail of physics lectures. I was sick and missed an entire month of school and your videos have allowed me to finish this unit in a few days. Truly revolutionary
