Great video, man!
Thanks man
Thx
Thank u
great work man!
You’re awesome
you deserve a peace prize for single handedly teaching every student on zoom university
To be fair, physics is the same whether ur in middle school or college level.
@@zachlol9701 what do you mean the same as 8th grade physics? This is ap physics 1 level dynamics. It might cover the same concepts but the questions are much more difficult.
This channel has taught me more than my AP Physics teacher ever will
This was taught in grade 10 but it is taught again in first year college
@@donwhite5180 lmaoo in Canada we don't even have physics as a choice till grade 11
Guys please watch the ads fully
This man deserves the ad revenue for how much he helps us all out
He's got a patreon and millions of views per vid i think hes good mate
How about you watch three times as many ads, while me and the gentleman above me skip them? 😂
@@The_Alpha_E nah he needs to watch 4 times as many ads
@@The_Alpha_E that pfp in 2024 is crazy dog 💀
@@nevermoresalt I wasn't aware profile pictures had expiration dates.
I never thought I could learn or understood physics problems but I must confess that you've changed that, now I am working physics problems and I have also been able to applied your method to other problems and I am doing it. We need people who can break complex information down and also explain things like you do. Thank you so much for doing what you right and God bless
That's awesome
I feel like everythings gonna be ok when I watch your videos. Thanks !
you can say that again
Ur MuM gAyE
Well put
@Sumit Singal Shanks In my opinion the parallelogram theorem is only good when learning how to understand components and how they work to solve an answer. Once you have that basic understanding then you can simply find the components and solve the problem. He has videos describing the parallelogram in his kinematics playlist if you need to use it.
lmfao same
No homo bruh, but i love you. thank god for ur existence bruh
I love him too lmao he helped me get a 92 in chem 12
lmfaooooooooooo. deadass, thank you god
Ong no cap
I've been spending two weeks listening to my professor but I haven't learned a thing until I watched your 3-hour video. You have no idea how grateful I am to you.
I loved at u
YOU ARE A LIFE SAVER! I got stuck with a pretty bad teacher and literally would've failed my exam if it wasn't for you!!!!!
Thank you
I HAVE EXACTLY THE SAME PROBLEMMM :(
Sameee😂
Same problem
i can relate
Dude this has *everything*
I'm getting 5 hours of sleep tonight, but thank you. You gave me an out for not paying attention for literally a month.
Edit: Nvm, two hours of sleep, but hey, at least I know stuff now
Edit: Alright, this has been amazing. I scored a 92% on my test while the class average sat at 75%.
wtf. I got 92% as well, and the problems we solved were unparalleled, but thanks to this channel I was able to apply the principles even though our quiz was a lot harder
A small price to pay for 92%
Set it to 1.5x speed. Makes the video ~55 minutes shorter.
@@AllMustJump Sure but are you really able to comprehend the concepts if you’re watching it that quick?
@@harshitgupta6856 If there’s a point in video that I didn’t take in a concept well then I just replay that part again at normal speed.
Bro I never ever commented to any of the videos on youtube in my LIFE! I live now in Germany and studying engineering. I completed my schooling 3 years ago, so its very difficult to recall the formulas and stuff. I should say that you are an amazing teacher I came across in my entire life. you are a SAVIOUR!!!!!!! God bless you. AMAZING SOUL!
You're like my academic oracle, your voice got me through high school and now it's getting me through university. The relationship I have with you fascinates me. You are the best!
I wondered why I haven’t made that many friends this semester..
I’m always hanging out with you!
Lol 😂😂 you made my evening
literally me
Nah that's a problem homie
💙
I am a Software Engineering student from Saudi Arabia, and I just want to say THANK YOU!
You have helped me excel in so many courses, you never fail to excite me about boring materials, you are the GOAT of teaching and I truly wish you all the best.
Friction starts at 1:25:00
thanks
I just want to give a big thanks to you, I signed up for my physics class and was so confused lost like I have never been in a class before, I had never EVER taken a physics class. So I went from knowing nothing in physics to getting a 100! On the first exam I cannot thank you enough
You do the best explanations, without skipping the steps. thank you so much for your time and work!
Birsen Doner man can never be hot
A great refresher from someone who can teach not just recite! Splendid work.
literally im struggling in every subject and when I look it up this man always pops up. HOW DO U KNOW EVERYTHINGGGG
Have a physics exam tomorrow and this clears up the material so well! I cannot begin to explain how much this channel has helped me with precalc, calc I and physics while studying to get an accounting degree.
How did you do?!
Your voice really soothes me. When I hear it, I know I'm going to be fine for whatever that's coming
I usually get nothing from these lectures.... I only depend on u guys!!! Keep teaching us.. Watching u from Zambia 🇿🇲🇿🇲🇿🇲
Zambia here 🇿🇲🇿🇲🇿🇲
True organic chemistry tutor
💯❤️
Most of us get nothing from lectures🇿🇲🇿🇲
I dont know what I would have become if you didnt exist. You tackle all the necessary problems that show up on my tests and I am greatful for you!
I hate watching ads but I let them play bc it’s what he deserves 😭😭 I have an exam in 4 hours
thank you for everything you’ve done to help all the students out there who’s stuck with a bad teacher. I really love physics but no ones there to explain to me, thank you for making such an effort that made such a interesting subject lovely again 🙏🏼 TQVM
You have helped me with most of high school calc, physics, and chem, thank you so much, and another thing that's nice about these videos is that people will always need them, this was posted 4 years ago but there are still people who need this kind of help, so thank you
yep , true
Having possibly my worst experience with a teacher ever and you saved me on the test for this unit and now I’m coming back to make sure I can do it again on the midterm. Thank you so much for the help.
I can't believe you're just covering EVERYTHING that our class covered this week in one video. I was so lost. Fell a week behind work, didn't pay attention in my lecture, tried to do the questions my lecturer gave us and just wanted to cry. Thank you so much for making this. You're raising an entire generation of engineers with these videos.
When I saw the picture of your video... my heart just cooled down :)
I am really grateful for your video!!! I am currently studying in Korea, so apart from the language barrier I did 2 gap years and forgot a lot. Although the video is long its worth it!! Its easy to follow and understand. Thank you so much!!!!
Dunno why you'd want to be in Korea it's ether a crazy militaristic dictator or the plastic surgery capital
Dude, God Bless you. Hace my physics exam in two hours and I've been studying since 7 am, you've brought my grade from below a 50 to maybe passing lol.
I couldn't live with my fail in Physics, where did that lead me? Back to him...
On behalf of students worldwide who have benefited from your videos - thank you so, so much!!
I think you make one of best videos on UA-cam. I have so much confidence in my academics after watching you. You were even a recommendation by one of my lecturers. One suggestion though is that you should make the videos shorter with more frequency or make a video on each topic you would have in one video. Love you....keep up the good work.
this video has helped me alot. i started watching ur channel when i got to 10th grade and i havent stoped since then. i have been passing my class with high grades.i love u. NO HOMO
I REALLY REALLLLY REALLLLLLY love this video! I have absolutely no words to thank you!
Shoutout to everyone here because they're trying to understand what Mrs Wessels said.
THE BEST VIDEO EVER. THANK YOU BEYOND LIFE. THIS IS A LIFE CHANGING VIDEO WISH I COULD LIKE IT A MILLION TIMES.
This guy knows wat he is talking abt,he is really a great teacher.thanx a lot for the help,most importantly all the energy u sacrifice for us to understand physics better thanx
All throughout chemistry and so far through physics, this guy has saved my grade.
when ur teacher doesn’t teach so you watch a 3 hour video on everything before the exam 😆😆
Dawg Literally me rn
You know it😉
😂am with you right now
You sir are a saint, please keep the physics videos coming they really help!!!
I wonder how many engineers you have molded and created man. I would not have gotten this far in engineering school if it wasn't for you. So I owe you my life for that
I am watching and say to my self i wish i had a physics teacher like you through my 20 years of study. Makes you understand the fundamentals not save equations in mind and be able to apply on real life applications.
Really appreciated.

Your videos are always well done and you are an incredible teacher! Thank you so much!
thank you so much for taking the time to teach. Now I believe it involves passion. This video really helped me. Continue with the hard work and keep on progressing.
AP Physics teachers never seem to take the time to actually explain material to students. Thanks so much for carrying me this year you are le’GOAT
You are an absolute life saver. Doing the job my professor cannot seem to do.
"close enough, we can live with that", lol everytime man xD. Tqvm, u make it looks so easy. Gonna ace my exam now!!
You're a better teacher than most of the teachers I've ever had in my life
love your profile pic bestie
@@marianlo1933 Haha thanks!!!
Thank you! I knew nothing going into the week of my test and ended up with an A+ thanks to these videos.
The tutor on Newton's laws was excellent. Loved his way of explaining concepts.
thank you so much. i really appreiate the time that u spent trying to explain all the problems. i couldn't make it without. again thank you sooooo much sir.
I have a physics test in four hours and i didn’t know anything before now I know everything thank
same bro wish me good luck
@@noreadingrequired4346 good luck!!
writing tomorrow. All the best to whoever is reading
@@rahulrathod170 good luck !
@@noreadingrequired4346 howd it go
I don't know how to thank you, your videos have helped me concentrate (yeah the ads are annoying BUT YOUR VIDEOS ARE WORTH IT) and actually UNDERSTAND PHYSICS.
Thank you so much! ❤️
I was with you on calculus and look at me now , we get to meet once again, but now for physics. You will be my forever hero.
god bless you man. do you take donations? You have no idea how much this helped me man
Thank you in the comments for explaining WHY we need to watch the commercial...to give this Professional Educator full revenue stream income. Some of us didn't know that.🥰
I want to thank you for your video's , they are helping me understand a subject I never took in School and your tutoring style is easy to grasp. Much appreciated !!!!! from a single mom redoing Matric to get entry into my Paramedical Diploma.
We shall have you just in praise , good sir.
Sorry to say that, but you should have listed the time coordonates of every chapter's start point. I really want to know more about topic 10 but I can't find the spot on the timebar. Anyway, cool video!!! I appreciate your work very much!!!
Yeah, I just made one
Thank you so much! I watch your chemistry videos since you make things easy to understand so I was thrilled that you make videos for physics as well :) I don't know how I would manage to teach myself everything otherwise
i have a university midterm in two days and this has helped me tremendously!!!!
At the moment 2:15:26 , you've pointed purple tension of m2 upwards , though it needs to be downward so you can have f2net=m2g-T
Love your videos man you're literally a life saver.
No he’s right
Wow this has helped me tremendously! You do an awesome job!
Thanks.
This is just so helpful, i am in class 10th and i am going for competitive exams, this video is extremely helpful for me as i could not understand this only by reading and our chemistry tutor totally cleared all my physics doubts. Thank you so much!!!
Thank you so much for helping me in AP Physics I, I'm on the verge of dropping out of the class but your videos really helped me understand my worksheet, I really appreciate your efforts in teaching : )
Yo I've been studying for my csets this has been helpful!
YOU HAVE BEEN SO HELPFUL TO ME SIR... YOU DESERVE SOMETHING BIG..
BBC?
@@rickyscollegescene3484 LMFAO
