oh my days, god bless u. My teacher is so trash at explaining and u literally made me understand everything in one video, i love you. ❤❤❤❤❤❤ i will subscribe and rely on ur videos, and i will get a 9 on my igcse cuz of u. ur students r so lucky
Thank you soo much sir!!! You made this topic 10 times easier to understand. Once I understood the concept, I started having a lot of fun in learning topic instead of thinking it was deadly and extremely difficult. It's all thanks to you!!
I have mine on wednesday next week and I was about to sacrifice this topic bc i didnt understand it and thanks to him i now fully understand it and btw if u dont mind was the physics paper hard?
@@shaizamaryam2002 imma give an overview, it was like my paper was on fire then my hand was on fire and then everything else was on fire and then i got cancer and died. Thats how it went (kinda hard)
@@shaizamaryam2002 dont be scared bro just dont commit the same mistake as i did, i played the whole school year and studied the whole syllabus like 1 week before the exam, as long as you understand the syllabus fully one month before the exam u are goos
omg no wonder i got so confused with the current direction stuff because like they literally said electrons but then the direction is the opposite?!?! like it was literally contradicting themselves... luckily i found you teacher omg i finally get it
Sir, you really are a life saviour !!! You just explained all at once in 2 hours which I've been struggling for two years... I'm so glad that I found you earlier before my final exams is getting close and you kinna make me love Physics now which I've been considering as my archenemy loll... Thankyou so much Sir! May God bless you Sir!
I just want to thank you so muchhh..... this channel helped me a lot .I never really liked physics but had to do it anyways and i finally finished today and i used ur videos to revise.Helped a ton !
you are a phenomenal teacher and i am so grateful to be able to have access to your lectures, you make learning entertaining and effective. always keep teaching!
thank you so much sir It helps with grasping the topics easily and developing an understanding which helps in revision or practicing in your terms Thank you so much !!
Sirrr, i have my mid term exams tomorrow and due to shifting schools, i am not done with the syllabus which is coming out in the exam, your videos helped me learn all of the concepts super fast. You are the third teacher i have met in my life so far who teaches physics with so much enthusiasm. Thanks a lot sir, u aint got the name mohammed ali for nothin. W
Thanks mister, like in school my teacher is bad, Im pre- IG though, we were studying these things at school, although Im the best in my class, I still understood almost nothing. But I heard about your channel from a friend who had the same problem before me, your videos really helped, especially this one. I will watch the next chapters' Videos too. EVERYBODY SHOULD SUBSCRIBE, AND MAKE THE PHYSICS A LOT EASIER
Thank you so much for making these videos man. It helped me and my friends a lot and made our final paper very easy. I appreciate it man. One small recomendation, you should start making videos on past papers too.
Tr why did u say the higher the temperature the higher the resistor and the lower current in 48:38 even tho u said if the temperature is increased the resistance will decrease in mentioning the thermistor
In the graph, the resistor was a metallic conductor that's why when the temperature increased, the resistance also increased but before that he was talking Abt thermistors which are non metallic, which decrease the resistance as they gain temperature
Mo Ali, I can't thank you enough! I have been struggling with physics, especially space and general topics, because of bad teachers, but your explanations made everything so clear and easy to understand. You stick to the syllabus without all the extra content that just confuses me, unlike my textbook. Plus, your funny jokes make learning so much more fun,your videos never get boring!! I have my exams next month, and I am aiming for an A* in physics, and if I get it, it’s all thanks to you! LOVE YOU TEACHER! Please consider making videos for A Level physics as well, It's going to be really helpful for me in the future. ♥🥰
Hello sir, I have been enjoying your teachings 😊 everything you have explained in a very simple terms and comprehensible. I would like to request if you could also have a video on college physics 😊 would be very grateful. Thank you
Allah bless u brother v good media u have made mashallah i watched complete 3 hours. v impressed by your skill set, everyone watch this video i greatly recommend it and it has a special space in my lil tinsy binsy heart
I literally wrote a mock today against next month exams and the last question you asked about why voltage is increased came out, and I just smiled thanking you so much in my heart. That was just one among the numerous other questions your videos helped me answer.
mr can you please do waves, they added a bunch of things about communications which i don't really understand. thanks a lot for this video, literally the only physics teacher i understand
i.swear.to.god you have singlehandedly saved my physics grades. I just know that ill manage to get above B in physics JUST by watching your videos. I thought i was so done for electricity but you just saved my LIFE! sir, i seriously dont know how to contact you personally for thanking you, but omg thank you so so so much.
