honestly have my gcse in an hour and this has just managed to explain nuclear fusion in 3 mins that my teacher struggled to do with 2 years! THANKS

This channel is honestly so underrated! I tell all my friends about you bc. you have helped me understand so much content that our teacher fails to explain properly. I wish there was some way that I could support you because you have helped me gain a lot of knowledge and you have definitely improved my grades and confidence

lol, its weird when you think about it, "tonnes of energy" seeing as in fact its like 1 trillionth of a gram

These videos are seriously useful. Thanks a lot!👍

[Rachel-pcvr]

Love this! Thanks for the help and great drawing btw.

[femfm]

amazing video. I screenshotted the ends of the concepts and made them into flash cards for my test. It did well. Tysm you have really brought my grade up in science 10 from a fail to a B.

[Yorstruly]

this was way easier to understand than most videos and it's short too! thanks!

[meenakshibhat]

Bro i love your videos, they help me grasp concepts in a very simple and easy way, plus these videos are very short, yet so detailed. Thanks a Lot 👍

We have created fusion here on earth, but the total amount of energy in is greater than the energy we can get out so it's not useful as an energy source.

[Nebularzzz]

This was a crazy good explanation! Thank you!

This channel will soon hit 1million subscribers.. The content is so informative and easier to understand :)

Really appreciated this concise video and its sister on fission. Question: how do we know for certain that fusion occurs in stars? Is this fact or theoretical?

[prisgila]

Thank you for making this video :) appreciate it yay✨

[Jorjia]

I finally understand nuclear fission and fusion after watching both of the videos. Thank you so much

Hey.. can anyone explain pls. At one point in the video it’s said that two LIGHTER nuclei fuse to form one HEAVER nucleus, but at the same time they say that the mass of both the smaller nuclei is GREATER than the one large nucleus, as some mass is lost as energy. So... how does this make sense?

[MusixandRandom]

0:26 video said He 3 over 2 Periodic table He 4 over 2. Is the remainder one neutron wasted as energy?

[kevinthiele]

at 2:19 u described nuclear fusion as light nuclei to heavy nuclei... did u mean small nuclei to large... as in nuclear fission 2 small nuclei produce a larger nuclei with a lighter mass?

[anissbenthami]

How does nuclear fusion releases energy when that same energy is what makes the two lighter nuclei stick together to form the heavier nucleus?
