The greatest difference between this channel and my teacher is that it doesn't try to cover the syllabus, instead it ACTUALLY HELPS.

I’m watching all your physics videos right before my physics gcse exams and you’re really helping me😭 thank you so much!!

My physics teacher is really not that good at her job so I used this before each test I have had. Now she has told us that she forgot a whole topic and so has set some paper sheets and made us just watch these! Thanks cognito for picking up for her!

This odd extremely helpful especially that each unit is in a different color

[marharding]

why did this video teach me more than what my physics teacher taught me in a year lmaooo

[Poncho]

Very informative video as always, good for catching up on stuff I missed in class 👊👍

[DrK-qigr]

I used this channel and it’s platform to cover up 70% of my syllabus and believe me I got an A

[thedataprofs]

This channel is underrated. It should get more views and subscribers :)
Very helpful video thank you

[sirkwamebota]

i have physics end of term exams tmro. thnx. u r helping me.
Edit: i got 90%. thank you.

Very informative; addresses the main idea in simple terms and cool diagrams to illustrate it better than my own teacher ! 😄

[alexandrmxox]

Great video! This topic is very confusing so thanks very much!

[lizella]

The way you teach is really clear to understand. It really helps me to do my gcse exams easily, Thanks for your teaching..! ❤✨

Thank you for the video, it’s really helpful. I just have a question: I don’t get how 1g/cm3 is equal to 1000kg/m3? I though that 1g is equal to 1000kg, so surely it should be the other way round?

[Dcrvuhnuhbygg......]

I don't know where else to report this error: In a physics practise question on density it goes like this:

"The density of sodium is 0.968 g/cm3.
What is its density in kg/m3?"

The two options are:

"0.000968 kg/cm3

968 kg/cm3"

And then it talks about dm cubed:

"Not quite! To convert g/cm3 to kg/dm3 you have to convert"

I think there is an error with either the answer or the question - maybe a typo.

Hope this was helpful!

Simple explanation is what matter in physics cognito is one of those who explain a topic clearly and simply not our school teachers who just teach and bah

[duaahmed]

Can you PLEASE PLEASE make videos where u Solve past papers u explain really well and most of the time the concepts are very clear to me but then when I open the past papers Idek where to start so pls, p.s this would be a great idea for u since you've run out of content to make...

In just 3-5 minutes, he imparts knowledge that would typically take a school teacher a week or more to cover.

Brilliantly explained ..World saving stuff right there
