Heyyy! Just wanted to say that I'm in my mock week and these videos are really really helpful!! These videos are the only thing getting me through triple science hahahahahahah, anyway, thank you Cognito for these extremely helpful videos! :)

Cognito can really be an awesome professor but he so kind, empathetic and helpful that he provides all of us the privilege to learn 100 % efficiently
He said right
No devices can be 100% efficient except cognito ~~~~

Btw thanks a lot for teaching ●_● ~~~

Has anyone realised the order of these videos matches CGP's card and revision books? It's actually a good idea- I don't know what I'd do if I had to make a channel on everything physics. Great video :)

Ayo last minute science hw due in tomorrow check ✌️😍

[joynwajei]

i've been using your videos for my revision of ap's and seriously understanding it.

i’m doing a renewable energy project in physics so this helped me a lot thanks :) 🙏

Sad that Nuclear power is still seen as a huge danger and not the thing which could save us from fosil fuel reliance.

[mysticxray]

Hi with all due respect, I just wanted to say that you mentioned 40% of energy used for transport and 29% used for domestic uses but what about the remaining 31% ?

If you don’t mind…

Who else is here because of online learning?

[Heatherisbetterthanuu]

Thank you so much I have my year ten mocks tomorrow and you really helped me

The thermal energy in heaters are transferred to the air by convection?

[GraceMahaffey-wyik]
