Helped me through high school, now helping me getting my engineering degree.. The man is a legend .. Protect him at all cost ...
too bad you cant use him once you get into the upper level classes rip
This is used in engineering degree ? I’m 16 doing this 🥴
@@gurisandhu7354 AP Physics 1 is a college level introductory course so yea
… I’m doing this in high school
@@m26munk58 bruh .. we all did this in high school. Physics course for engineering is more advanced. We gotta review the basic
Soothing sound
Clear accent
Conceptually explained
Sequential
Alot of examples
Clear background
All tpoics available
To the point lessons
All sceince subjects available
U r awesome sir.God bless u
May you prgogress alot
For real. My physics teacher posts tons of videos instead of lecturing over zoom (which I completely agree with) but she posts videos of people trying to be as whacky as possible to make science.. fun? But it is just soo damn distracting. This is always where I choose to learn.
100% agree. If anyone reading this is an aspiring instructor, this is the quality of instruction you should strive for in the long run.
I thought this was a time stamp of everything covered. Boy was i wrong
Most importantly, dark mode
@@axelc6125 lmao true tho
I feel like you're at a point now where you shouldn't specifically have "organic chemistry" in your name lol
Yeah, but it might be too much to change his name now with all the subs he has gained
his name is organic chemistry probably because of the course of he studied
@@bee26103 ppppppppppp LLP p
ppp L LLP p lo LL Llp
True
wow. the difference one man can make on so many people is insane. ive been watching your videos for a year and a half and they NEVER disappoint.
hey if you're watching this the day before an exam... you got this ! i believe in you
Ommo ommo ....thank you sis,I'm feeling zat I will make it tho
Thank you!
true true
I'm watching this an hour before an exam
32:08 tension force prob
44:06 ladder
Thanks 😁
Tnx Bruh
bruh you saved me almost an hour thanks
What's A God To A Nonbeliever? More like, What's A The Organic Chemistry Tutor To A Failing College Student, thank you sir for your service. 1 like is 1 respect
WTF? We have this shit in highSchool!
@@Irioberzan first year uni includes high school review
@@Irioberzan a lot of colleges have a bridging (foundation) course for some undergraduate students as their first semester in college for those without a GCE A-Level, IB, SAT2, American Diploma etc... so that explains it.
@@Irioberzan Yep in university you get to take again things you've done in highschool... So i would suggest you to study well subjects you intend to pursue at uni (these were some of my regrets lol) and that will make your life much easier
A savior
your channel deserves more attention
It's beyond under appreciated. It's insane.
Agreed!
He has almost 3 mill subscribers
@@nemifjord7119 correction he got to 3.21 million subs
If one day he says he knows the secrets of the universe i'm gonna believe him
Thank you for helping me prepare for this Physics exam tomorrow that I need a decent grade on. You make everything sound so much easier than when I'm at lectures
As an engineering student, subjects like Physics, Calculus, and Chemistry are some of the important subjects in this course. But not all students can immediately understand what the professor teaches in only one sitting. This video gives a great introduction to static equilibrium as this topic is very important for engineers. It is essential since it is the engineer's responsibility to develop and construct a structure that is stable and does not fall, slide, or tilt.
Static equilibrium is not an easy lesson and there are many formulas that need to be remembered but the lecturer of this UA-cam channel gave an easy-to-understand explanation of the topic so that students could understand it right away. He also gave real-world practice problems to further deepen the students' understanding of static equilibrium. Furthermore, the ability to rewind a tutorial video on social media will be very helpful to learners if they are having trouble understanding a part of the lesson they are studying. The video is a guide for students to clearly understand those complicated topics. However, it is crucial that students have their notes from discussions with their professors that could be a big additional help upon reviewing the topics that had been tackled.

Bro your tutorials are freaking awesome. i literally could understand better after watching your videos. Dude legit speaking, please make more videos. Your explanations are so acknowledgeable man. Thanks a lot, truly appreciate.
"please make more videos" he took your advice and is making more videos 😂
Just want to say that your lessons are really good. The way that you explained everything makes me wonder why I even signed up for my physics class in university, when literally I could just watch your videos.
I love how every time, never fails...”according to SOH-CAH-TOAH” every time an angle comes up.
Nowadays I completely stop being stress when our teachers say "tomorrow u will take exam" pishhhh who cares ...I go home n search ur channel n knw u made a video abt ze lesson zen study wiz u n pass wiz a great grade zen I come to zis channel n start liking ol ze good comments zat u gate.
Thank you 4 making ma life cool n calm.
What the hell, how do you legitimately type like this
@jacobandyou
You couldn't read it but I did
I feel safe to say, I’ve understood more than I had known, I always thought this was hard but now not so really, I mean it has its complexities but it’s understandable with the right teaching 🤙🏾
Love how this guy is in depth while not being overwhelming in the slightest
true especially when your learning during the pandemic
thx bro, i finally understand the use of moment arm. Our physics teacher doesn’t even taught us…
honestly this guy is saving me in college lmao -- I'm taking an introductory physics course, and even though my high school teacher was great, college is just a lot harder with the content. plus, even though I'm a math major and I love calculus, I DESPISE physics and have never been good at it ! so this video is super helpful for me !!
also, my calc 2 class is online with a terrible professor, and his video on the convergence and divergence tests literally saved my quiz grade, honestly idk what I would do without the organic chemistry tutor ! the videos save me a lot of time since they're faster than studying, + I learn better with the crash course-style bc of my short attention span, not to mention everything is explained so clearly -- I can see why certain steps are being taken instead of simply memorizing how to do it, so I understand everything a lot more clearly. overall, thank you - these videos have been extremely useful to me and countless others :) !!
we all love you so much, you deserve everything that this universe can give you!
What to say??!!!! Whenever I feel weak in a topic, I search the web and when find out you made a video, no matter how mlong, watch it completely. Thabk you so much. It helped a lot😊🙂
you are a blessing to us who are struggling. this helped me a lot thank you!!!!!
Well-explained topics and plenty of examples, this channel has helped me a lot especially on my physics in engineering. Applause.
I understand you better than my own professor that explains in dutch!! Thank u sm
Your explanation is excellent whether in math or physics or even statics, you're the best
the most coherent and concise thing ive seen in physics
Second hanging sign problem - I did have to watch it 5 times for it to really sink in, but now I think I finally understand the concept of Torque = Fr(perpendicular). I kept asking my professor how it relates to SOHCAHTOA in geometry because I knew there was a connection. But he kept telling me not to think of it that way. Your explanation is so clarifying. Thank you!
You're probably an engineer by now, but I'm sorta old school and don't trust the whole rFsinθ thing, so I definitely go the trig route. It's a little slower but I can see exactly what I'm doing.
You are the single most valuable resource I have for studying physics.
Just hearing him walk through problems has helped so much more than any teacher I have ever had.
Thank u.. at first its so hard to understand because its something new for me..but until the last example, I understood 👍👏💕
This man should be awarded a nobel prize 🏆
Why when I watch your videos EVERYTHING seems so easy to understand?!
Thank you)!
You clearly explained everything! Thank you!
Thank you for all that you do. you have helped me more than you know
you are helping me achieve my dreams by passing this class. i wouldnt be able to do it without you .
Thank you so much for taking your time to make this kind of videos. You solve the problems step by step and explain them well, I appreciate your hard work.
i literally go to uc berkeley and you explain this 1000x better than my professor
Excellent pace and very illustrative problems, thank you. However, in the first ladder problem, was wondering why you did not consider Fwy at the wall. Then, in the 2nd ladder problem which was the last problem, you mentioned to assume no friction at the wall. So I assumed the same applied to the first problem too. Would be interesting to solve with assumption of friction!
thank you so much for creating these video. literally a grade saver.
Thank you so much for this lesson, it's actually very difficult to find good physics teachers like you
I really understood everything 😊
Your videos helped me out so much. Keep up the amazing work
Your videos are the best!
I'm honestly not kidding on how helpful this was for my semester
Thank you so much! Your videos help a lot for my Physics class.
Honestly you cleared up Equilibrium for me, you are awesome
This man is a legend. He explains it 5000 times better than my teacher. Thanks, Organic Tutor.
kudo's to this guy to make me have confidence for the statics exam I have in 10 hours within an hour
Here I am again, Mister I cannot express how grateful I am for your videos , I genuinely love you
Came here and thank god for this video and your voice.
I don't have much words to praise you but I'll just say God bless you 🙏, you are a hero
Mate your a lifesaver, instantly subscribed!
i love all of your videos, it's attractive and easy to understand. thanks for the helps teacher!
Another great video! I learned plenty.

We know that:
Sum of forces = 0
Sum of clockwise tension= sum of anti-clockwise tension
T sin 30 * 2m = 200kg(9.8)(2m) + 30kg(9.8)(1m)
Tension = 4214 N
THANK YOU YOUVE SAVED MY ENTIRE LIFE
this channel help me so much , appreciate it thanks a lot for this video , this narrator deserve to get much money
Men, is this guy modern day Einstein? Damn cool , i love your tutorials ,
Salut 🙋🙋🙋
Perfectly understood thank you sir.😊👍
You teach at a perfect pace
Wow, thank you so much! These videos are amazing.
thank God I found someone who can actually explain it direct to the point
Thank you very much for all these videos. I had the unfortunate luck of getting a professor whos teaching philosophy consisted of "ill give you a minute to look at the board" without explaining anything. I would be failing if not for you and these videos.
Thank you very much for your hard work on this video.
the dude has explained theories that I haven't been able to understand for 3 years of my high school in the first 12 minutes
Thank you very much for what you do , your channel is really helpful
Organic Tutor ..ulikapondo Sana🔥..here in Zambia @ the University of Zambia you're helping a lot of Natural science students ✊🏾
quite useful for jee concept clearing too...was damn stuck on ladder and hinges
My man, keep up the good work.
Thanks alot. You helped me study for my mechanics quiz
Thank you very much for this well detailed and explained video
It really helps
You are better than my physics teacher. Thank you
Thanks a lot man...! That was very useful...
god bless you sir this video is why im passing my engineering class
You're still my best teacher 💓
your videos are the only reason I have passed all my college classes lmao ilysm
Same!!
Damn you guys do this shit in college? In Australia I'm stuck doing it in high school :(
@@stephanietrevisan7672 me too in high school lol why
@@stephanietrevisan7672 in high school AND college. And i still have to go back here for enlightenment
Me too in college
When I search for a topic, I feel relieved when I see your channel lol. I know I'm safe now😌
That was very helpful specially the last 2 questions ,thank u very much !
I like pausing the video and trying to solve myself. But if I don't get the right answer you do a good job of explaining the problem so i can find my mistake.
Which grade are you???
you are a life saver my god what would I do without you
excellent videos with unique charm!
This guy deserves noble only vedio enough before exam thank organic chemistry Iam from somalia
you have saved lives, thank you.
cool video, helped me out. Thx!
