I subscribed to you because I'm in organic chemistry and I found your videos extremely helpful, but I'm also in physics and just stumbled across these videos and I just need you to know you are literally the reason that I am passing any of my classes right now :") your videos are so much more helpful than my professors will ever be
@@steve4718 physics doesn’t change depending on where you’re at in school lmfao still gotta learn the basics in college (think abt the amt of people who haven’t had high school physics in years or at all)
@@yikes3442 yeah here in Germany they make us study these things and statistically 70% of the class has taken physics already in school meanwhile i come from a different country where the last time we had physics was in 10th grade during the lockdowns
this helped, my physics teacher doesn't do a lot of teaching (basically none at all) so having alternative explanations this simple and easily accessible is huge.
Thanks you so much for making this wonderful video. I failed the physic exam last week because of this. But I am not going to let that happen again. Which is why I am searching on youtube for it and I saw this video. This video teaches me a lot. My teacher don't explain the concepts as good as this. Then again, thanks you.
I almost got through my engineering major thanks to this guy. Then covid happened, and this mixed with all this stress building up just broke me. Since then I swapped majors to digital media, got my degree and now I'm just kind of stuck not knowing what to do with my life
Oh my fucking god YOU ARE GOD These r da first few problems/lesson in My fuckin physics class. And SOMEHOW you PERFECTLY timed your past 2 uploads to when i LITERALLY fuckin needed them You are an underrated educational yt channel and you DESERVE all our respect.
Hi, there's something I'm confused about. When considering the rotational inertia of the pulley and doing a problem with it, it becomes apparent that each side of the rope has its own unique tension that is not equal to each other. In this case, doesn't the method to solve problems without the consideration of pulleys violate this principle? What assumptions are made in order to solve it like this? If it's the existence of the pulley itself that causes the uneven tension, what exactly is the pulley doing to the string to essentially split apart its effects?
Great video, although, my main problem in understanding was when solving for tension. When we made the tension equation, why couldn't we plug in the value at that moment itself?
when he was solving for the acceleration he used T= to make two equations to set the whole solving part up. at that point we did not know the tension, which is what he solved for later
i have perfect grades, A+ in all A-level sciences and math, except for physics where I have a B because my teacher is full of shit. You're seriously a life saver.
No because they go in different directions T goes up and m2g goes down for exemple let's say you took 3 steps to the right and then 2 steps to the left the final spot from the start is 1 steps to the right because 3-2=1 so it should be T-m2g. Dont know if I explained it well hope you understood
so then a = (m2g - T)/m2 and a = (T - Mkm1g)/m1 also work if you have tension. That's pretty cool. But because we haven't found T, we're substituting the T instead.
My physics is a little more complicated than your videos, because my prof is a little wild. However these videos have helped me pass like 4 classes so far 😂
hello i appreciate your work here but my question in the first 01:00 is ,can we consider T as being greater than th force acting on the 5kg object? i have an assumption that because m1 weighs 15kg its tension on 5kg would be greater than the force pulling the 5kg object am i right?
It’s greater because the force of tension is a positive value while the force of the object is negative(5*-9.8 due to gravity acting in the negative/downwards direction).

You have made the living hell known as physics slightly more manageable and I thank you for your service 🙏
Literally saved me the day before my physics test, keep up the good work! You earned a subscription for this one!
I just had my first calculus test and aced it thanks to YOU Organic chemistry tutor!!!!

I'll never forget this again, thank you
I wish to meet this guy someday so that I can shake his hand. Utmost gratitude man.
bro you are totally a legen you got me thorught a lot of school prombles. God blesss you and your family
All this self-esteem-building knowledge! I think I ❤ you.
Solid video. I also used your videos to study for the DAT and have some interviews lined up. Thank you so much!
I was so confused with the positive and negative signs, but when u talk abt it using the x and y axis, it makes sm sense!
You sir are a god when it comes to explaining things.
Everyone remember to like their video. It means they will most likely make more of this and makes it easier for others to find them
The way he still inputs the values in the calculator , although he's sure his answer is correct...,👏👏
If I ever succeed in becoming a doctor, I will pay you a lifetime worth of appreciation and snacks. Thank you 💕
Sooo who r u now ? Still a student ?
Thank you!! Pulleys are so much easier with Sum of forces over mass.

Watching this 30 minutes before the exam
Congrats on almost reaching 3 million subs! But its about time you get a better mic no? Other than that your work is wonderful!

(the assumption made, by the rope being massless, is that tension is evenly distributed in the rope)
Frictionless pulley; massless and perfectly inelastic rope
Massless pulleys to be added to the assumptions
In 5:42, how come a_x is +, a_y is +, but m2ay -? Is it just becausethe m2g vector is pointing downward, or is there another reason?
Thanks a lot 🌸🌸😭

Thanks for awesome video.
I love this guy
Your video is always helpful tnx alot
isn't net force always addition so for the pulley problem around 3:29, net force for Y should equal T + m2g?
No because they go in different directions T goes up and m2g goes down for exemple let's say you took 3 steps to the right and then 2 steps to the left the final spot from the start is 1 steps to the right because 3-2=1 so it should be T-m2g. Dont know if I explained it well hope you understood
got it thanks@@ggmegagg
so then a = (m2g - T)/m2 and a = (T - Mkm1g)/m1 also work if you have tension. That's pretty cool. But because we haven't found T, we're substituting the T instead.
Thank you so much, life saver
Pardon me. 14:44 How the Fk=(constant) m1(g). How is that the force is accompanied with g? Isn't that it is some kind of (a)?
You are too good
God bless this man
Thanks you so much

hello i appreciate your work here but my question in the first 01:00 is ,can we consider T as being greater than th force acting on the 5kg object? i have an assumption that because m1 weighs 15kg its tension on 5kg would be greater than the force pulling the 5kg object am i right?
It’s greater because the force of tension is a positive value while the force of the object is negative(5*-9.8 due to gravity acting in the negative/downwards direction).
The tension force is the same for all rope right? that’s why we can calculate it with any one of the two equations?
Yes, same as the acceleration
yes. you can choose any of the two
