Could you help a homeschool mom out? My son is 9, and we are doing basic physics. We were doing simple volume and density expirements, but got stuck on multiplying a fraction that had a prime number. A cube was 1 3/16, so we multiplied 3/16*3/16*3/16 = 27/4096... but I cannot for the life of me simplify this! Any help would be greatly appreciated 🙏
@@angelaearley1639 you can’t simplify 2 prime numbers by definition. 27/4096 is already in simplest form
@@meswag1233 thank you! I was feeling crazy and thought maybe I had missed something. We did end up using decimals to keep it simple.
@@angelaearley1639 wnsnjdnfbyby
thanks
You got me through highschool with a 100% in physics. I studied very hard chemistry and physics with your videos in order to get into med school. Now that I’m in college studying med you’re still helping me with them. I’m so grateful for it.

I don't know if you will ever read this, but I will deeply thank you because I am getting over 90% on my tests just because of you, without you, I would not survive math and chem and physics. I am sure you helped a lot of other students like me and they all benefit from your videos.
Do you have any account that has subscribed to his channel on Patreon? I need it but i Cant afford it :(
This channel helped me so much since my teacher can't explain anything properly so I always come back to the channel for help, Thanks a lot and Keep up the good work.

you are the best youtuber ever, I'm twelve years old and when I was 11 I got sick of being called stupid and dumb, and so I daringly said that I would learn calculus (I didn't even know what calculus was, lol). I began to search it up online and decided to start with algebra and basic physics, and while searching I found your channel. IT HAS BEEN A MASSIVE HELP. I am know learning trig, and also recently got into computer programming too (I'm making an 8-bit computer rn lol). I'm thinking of documenting my progress on my YT channel (idk if that would get views tho). Nonetheless you were a massive, and I'll repeat MASSIVE help in my journey. You've done so much for me
1. Now my friend thinks i'm gifted bc i'm gud at math ( i luv it)
2. My parents are EXTREMLY proud of me (that's one of the biggest things i'm happy about)
3. I know longer insult myself for being too dumb
4. It's helped a ton, bc now classwork is pretty easy
5. I can help my sisters with their math work :D
You are the MOST underrated youtuber ever!
@Luner Link ik, I'm trying to :D It's much harder to get everything set up than i thought it would be
Nice bro good luck with ur computer project and I wish u more success

Man, you're one of the best things that has happened to me since I was announced I had to take a Pre-Calculus test for my university. You've been an absolute savior, and all for free. Haven't taken the test, but I am confident that I will do a good job, better than if I had to take this journey of learning/refreshing math topics in general. Thanks a lot.
how’d you do on your test?
@@gabcooky he did not make it :(
jk idk.
Teacher is explains this lesson for 5 days and we didn’t understand
But u explained this for one video and we understand WOW
Hello everyone. My channel offers a lot of videos such as: limits, integrals, more difficult exercises. Please join all the students to learn. Thank you!
Hey man u okay it just past a month since u post your last tutor video
The short method to solve the problem is to use this equation
:v²=u²+2gh.Solving this equation :
v²=u²+2gh
v²=0×t+2×9.8×700
v²=0+19.6×700
v²=0+13720
v²=13720
Taking root of both sides.
√(v²)=√13720
v=117.132
Thus final velocity is 117.132...
hey man are you okay? its been a week, i hope you are just having a vacation or some free time, be safe ✌️
Good day sir, you have been doing well for we the Africans especially we that sat to Wassce exam but frankly speaking some of us can't afford to be part of your membership group 😢 due to the finance but I and any other guy like my type we are pleading for you to create way for us to be having free materials on topics like this. We pray God almighty continue to bless and protect you
you saved my physics
you are the god of knowledge
please keep up your nutritious work!!
I am about to take my interance test after a month I really hope that I will finish in time with the help of your videos😭
is he ok? im kinda worried he hasnt posted in a month
I'm also worried; he hid his subcount too
i miss you :c
I thought I comment on your most recent video as a cry for help: PLEASE MAKE A CONTOUR INTEGRAL AND DOUBLE/TRIPLE INTEGRAL VIDEO! no one makes videos as well or as understandable as you, I am in dire need! my calculus exam is in two weeks!

Hello! I always watched this channel for all my math, chemistry, physics, and statistics classes. I wanted to get help with my biology classes by watching this channel but unfortunately this channel is incomplete with biology topics. Do you guys know a channel or website similar to this where I can find complete biology topics? I am currently preparing for my SATs
Maybe try looking in khan academy there you might find something
u might find ap bio vids from 2020 on the college board channel

Please upload a full session about sound it would be very helpful for my final exam.....
Thank u so much for ur help...
this guy is just an angel descended by God, I wish he was my wife.
and i wish I marry him so he tech me physics 😭.
Velocity did not decrease downward. The negative only indicates that direction of the vector is downward
Does anyone know why is he not uploading any videos? I really like his channel, he explains really well.

Truly doing the Lord's work. Finished with A's in gen chem 1 and 2. Taking gen. physics 1. You've been a blessing. Thank you for these straightforward, easy to follow explanations.
you have become my physics teacher at home
Why do you not teach Uniformly Accelerated Motion?
This is our topic before we have that and I wanted to atleast grasp the basic fundamental knowledge before we go on this topic tommorow lol
I like the way you teach more than the other TH-camrs and I'll say I learn more here than my teachers could (because I'm dumb asf and for some reason the way you teach isn't boring than some others I don't know why lol)
I know your not gonna see this anyway
So I guess I'll have some sort of advance watching on our lesson for tommorow XD
thanks for saving my life again
thank you for this very complete tutorial
plz add more video on biology course... like Genetics....
First
Oh thanks, my grade is safed❤️
He has disappeared again! It's been 2 months since his last video!
Please bring a discussion on the topic"first order exact differential equation"!
i have a question, my teacher chooses the direction of a falling object to be a positive and then the upwards direction to be a negative, so is the value (positive or negative for velocity) based on what we wish to choose or not?
Lets just praise this guy, without degrading others especially our teachers.
I don’t even wanna talk about my physics teacher at this moment tbh
Man I have my chemistry final tomorrow and you just helped me finally understand chemical equations. Thank you man
Ps because of you I got a 100, highest grade in class by two letter grades
But this is physics class!!!!
@Aniket Ranjan what does that have to do with this video
Where are you pls continue 😕😕😕😕
Take care always JG, we can't lose you. I still have 4 and half years to go through. I can't do it without you. You're a genius.

would be very helpful~!!!!!!!!!!
9:02 This is why i don't like introductory(?) physics. We can literally get different answers by using different equations in the "4th big equations".
If we use the formula s(t)=1/2(a)(t), we would get s(5)=(-4.9)(5^2)= -122.5. Since distance is a scalar, then we can just remove the negative sign and get 122.5. Since the definition of speed is distance over time (speed=distance/time), then speed=122.5/5 = 24.5. This SHOULD be true because all i did was using the definition. However, the video uses velocity final and speed interchangeably, which also make sense to me. So which one is correct then?
Can somebody explain it to me why i got different answers?
EDIT: I'm 101% sure mine is correct since multiplying my answer by 5 will give the exact distance, while multiplying the video's answer by 5 would give a different distance (feel free to correct me btw).
I think the flaw in the video's answer is that it uses velocity and speed interchangeably. While sometimes it can be used interchangeably, but as we can see here that it doesn't work for this problem because the answer shows the velocity at that exact moment (velocity final), not the avg velocity.
Nonetheless, i still believe he's more knowledgeable than me.
I have a question. Acceleration due to gravity should it not be positive if it’s downward motion
Do you know what do physics and I share in common :
1- we both hate each other
2- complexity; in other words we both find it hard to understand each other Like I literally watch multiple videos which can add up to like a 2 or 3 hours and after I really understand the concept well, I realize that the concept was really easy to understand and that it was only wasting my precious time
Physics is literally the only subject that I find hard to understand and get into my little head
But any way thanks to you organic chemistry tutor for making those concepts a more less complicated
Pls come back I need grades
عاااش والله ❤️
ههههههه اخيرا شخص عربي
What I notice is that the u took up as positive...
What's if the question say calculate using down as positive. 👀
Is the acceleration remain negative or positive.???
12 years old in age, and I have huge interest in science and maths! You are a legend, I just randomly scroll through your channel, and see cool topics which I want to learn. Even though most of your content isn’t taught in my year group, though, I still have giant interest, and take notes and save them in my notebook for the future when I need them! Your content has also helped me a ton in presentations in science, where I did a presentation on Charles Law. You are the reason my classmates question what I do at 2am. Thank you so much! You are amazing mate! Cheers! 💜
If I become, my dream job, a doctor in the future, it’s because of you man! THANK YOU KINGG! 👑
you must be hella smart. im 16 struggling with my physics class

Bruh he hasn't posted for at least 2 months
I'm scared and crying rn
Hope you are ok
For those that want a substitute for this legend's uploads for the time being: I continue uploading at least twice a week! It might help some of you :D
Dude I just want to say thank you for making these videos that helped teach me Algebra Concepts and Pre-Calculus back in April 2019 until now. Also thank you for the various video tutorials on other subjects such as Physics, Chemistry and some Biology. You and Brian Mclogan are of great help to me and other fellow students.
OMG! you are such a blessing for all students!! Why can't all the teachers just explain the way you do? They make everything so complicated. Thank you for making me understand physics after so many years of studying it!!! Keep it up!
Like seriously, he's so calm 😢

When I gave this question to my students and I mentioned two balls, there was an uproar in the room, so I changed it to two stones in my next class....😂
Why is it -9.8 if it's acting in the normal direction of acceleration due to gravity
Hi! I know it's been 3 months but is the acceleration falling down always -9.8?
all need to) Repent, for the kingdom of Heaven is at hand. Jesus is coming ⏳⌛️. If we confess our sins to God, He is faithful and just to forgive us our sins.
I'm not gonna lie, I'm coming across your video for the first time, I can boldly say, this is my first time understanding physics without any doubt,I have really learnt a lot from here
How to be like you who knows everything in STEM subjects and also teaches them so well? Did you practice them a lot in college? Or are you naturally good at science and math subjects?

Which curriculum do you post on this channel US or UK secondary certificate or else or post high school topics??
I have a question, if anyone can answer. In the last question (question 5) why did he used the displacement -700 instead of the distance, 700? Cause I used distance 700 and got the wrong answer
I said it once and I will say it again....this is the best channel for learning Science and Maths...

Hello, I noticed that in one of your equations where the ball falls of from a cliff downwards, you said that the gravity is -9.8 which i think is wrong because the gravity is acting downwards in the direction the ball is falling which means the gravity should be positive
I hate this stupid class soo much
Can you make a lecture for MOSFET and feedback amplifier? thank you :)
for your biology series can you do "hardy-Weinberg equilibrium" questions
this guy has more videos than subscribers
Man you make my physics teacher look stupid
0:03 AYO
Omg I had my speakers full blast smh
In question 3,it says “and hits the ground”
If it hits the ground doesn’t that mean that vf=0
Bc if it hits then it’s gonna stop,right?
God bless this man
Hey... Why not do face reveal
Thank you so much! Your videos helped me understand everything in Physics❤️ You always make it easier to understand. Keep up your work!👏 God bless you sir 😉
8:46 In this problem you could do -9.8*5 and get the same answer without doing any other work. This won't work in all instances but the reason it's possible here is because if the ball accelerates -9.8 m/s^2 meaning the velocity increases -9.8 every second and there are 5 seconds.
I really hope you know just how much you are appreciated...thank you so much really.
um sir its actuallyyyyyy 9.81 m/s 😡
You are wrong
Amazing teacher that can cover physic, math, chemistry. The explanation is so clear and provide the examples right after the lecture. You should get the best teacher award. I wish I could have a teacher like you 40 years ago.
Plz Mr organic chemistry tutor I need a tutor about torque unless my whole life will be destroyed plz
I have a doubt in the last problem.
The second subdivision in the question states that the velocity of the ball just before it hits the ground ,but we have found the time 11.95s where the ball hits the ground
so free fall doesnt take into consideration of mass?
Yes free fall is independent of mass
THANKS MY TUTOR
Wont the 10gram ball hit the floor first since its heavier?
Dear Mr. Organic chemistry tutor,
Would you be able to do some videos covering vector calculus - topics such as stokes and green theorem and so forth?
You are very intelligent 🧠🧠.You made me understand a lot of things. I love you bro.
The force of gravity pulls harder on heavier objects,
but heavier objects need more force to be accelerated.
For gravity, these effects cancel each other out. :)
If ur 9th lets enjoy party on comment
