Hi I just got my gcse results thanks so much cognito I could never have got my 9 in physics without you!!

[isabellaelizabeth]

I just wanted to say thank you for this! My physics teacher did an online lesson on this for an hour I didn’t understand it at all, watched your two videos completely/ confidently understand this now! :)

[maxmarino]

Hello, your videos are so well made and I seriously appreciate the amount of effort put into them! Keep it up 🤗

[luxmeramesh]

6 mins and 14 secs did more to my life than 2 weeks taught by a teacher with a PHD. Your videos are so helpful thank you so much!!

Watching these with a gcse in two hours - I just wanted to say thank you for the hours of work to make sure we can all understand the world around us

[nemsis]

I've been using your videos for the past few weeks for help with all my science revisions for my upcoming end of year exams, they really do help me understand these topics a lot and sciences are usually my weakest subjects. Especially Physics.

[bakribhai]

Mate your gonna go down as a legend based on how helpful your videos are

[abdevil]

Such a nice videooo !!! My teacher could not explain this is less than a week but you did great. I understood everything. May God bless you

[ujycvwh]

Me here the day before m exam trying to learn the stuff my teacher has failed to teach properly thank god for cognito 😮‍💨

[jingzhao]

Quick question: "total work done remains the same" -- is that saying the total work done by the ENGINE doesn't change (isn't doubled), or the work done by GEAR A is the same as that done by GEAR B?

Great video, so thanks.

[mominaarshad]

Very good and understandable content, whenever i study from my books and notes, i always watch ur videos in addition ❤❤❤

[bqrjvyg]

I dont enjoy physics, but the illustrations make it much more interesting to learn about! Thanks for the simple explanations

[StrawberryS-vkmy]

Hi Cognito! I want to ask so the larger a moment is the object will turn into that direction right?

[guliiusmonova]

hello, your videos are really helpful, thanks

[paulward]
