he literally explained speed/velocity and distance/displacement in 20 minutes, I need him to be our physics teacher, right now
What is this hard in school or something?
@@thinginground5179 no it just takes months for them to teach one thing

glad it helped
@@Relic075 it help alot
You are the reason that am alive
Notes for this video i made:- use them for studying i only write stuff to memorize the concept but it just turns into notes after like 5 minutes
displacement = Pf - Pi
distance is scalar quantity
displacement is vector quantity
Distance = speed x time
(d=Vt)
but
Displacement = Velocity x Time
|Speed|
scalar + positive (magnitude only)
|Velocity|
vector + positive or negative (vector quantity/magnitude + direction)
.'. speed is always positive
velocity is positive OR negative
________________________________________________________________________________________________________________________
important formulas regarding speed and velocity
_______________________________________________________________________________________________________________________
Average speed = total distance
--------------------- .'. v=d/t (speed in this case)
total time
/
average velocity = displacement/ time
/
acceleration = ΔV / Δt OR Vf-Vi / t
anytime velocity is positive it means acceleration is increasing
anytime velocity is negative it means acceleration is negative
a=+ means V▲
a = - means V▼
[final velocity = initial velocity + acceleration + time
Vf = Vo +at]
gravitaional acceleration of earth = -9.8 m/s² (gy)
gravitaional acceleration of moon = -1.6m/s² (gm)
since its negative it means it either is in the negative quadrants
and its vertical so its y axis below

=========================
Newton's First Law of Motion
=========================
An object in motion will continue in motion unless acted on by a force.
{important forces- Tension(rope, string, chain XpullingX )}
[[best time stamp to learn this concept 48:00]]
=========================
Newton's Second Law of Motion
=========================
F = ma
\\Fnet means the sum of all forces\\
summation or sigma (pronounciation) :- ∑
net force in y direction ∑ Fy = m x ay
net force in x direction ∑ Fx = m x ax
L Fnet = m x a L
(m means mass and a means acceleration)
Note:- Always write acceleration m/s^2
with the square for s

Thank you
O my god, You are a W.
You literally saved me 40 minute of watching
Saved me a lot of time
You’re a GOAT bro.
This literally is the first time in my life I actually understand a physics class. Congratulations! You rejuvenated me!
and how would it figuratively be the first time?
@@sharky2675 Stop being a smart ass
Congratulations
This video is the very meaning of "not all heroes wear capes" because this mans is my hero and I APPRECIATE the heck out of this UA-cam channel. Thank you so much for all your hard work.
how do u know he is not wearing a cape?
Lol
@@manoloscheers5251 good question
you have taught me more in 53 minutes than my physics teacher has taught me in a year. thank you.
That's because you didn't listen to your physics teacher.
@@schmetterling4477 exactly lol
@@colewalker2916 That's what my physics teacher taught me about teaching: most high school students don't get it. It's not even a matter of individual motivation or intelligence. Physics has a tendency to "not stick". I have asked colleagues from other sciences (chemistry and biology PhDs) and they all told me that they didn't get high school physics. That's life.
@@schmetterling4477 .. or maybe you shouldnt assume someone's position/status because of your own experience
@@stikoes4057 What's my experience?
The existence of this channel made me question the purpose of our physics teacher.
Nice nice
This man taught me more in 20 minutes than my teacher did in 1 week. Huge applause to you. Please keep it up. We NEED people like you in the UA-cam community!
This will save someone's semester early if they see it right now.
That’s me I’m that somebody.
Aa m
You're so right, I will be one of those 'someone's'.
It did
I am that somebody
That moment when you learn more in UA-cam for free than your professors
Legit so true
Thats why college is a scam
@@randomcubing7106 no just a certification of learning
@@mjs2016 Yes that's it.
@@randomcubing7106 College isn't a scam. You pay to learn a structured curriculum which is learnt by everyone else who goes to college. It gives students a universal knowledge even if it could be obtained through other resources, sometimes being free like UA-cam
I never took physics at school but now I am interested to learn the basics of physics and this is the only UA-cam video I've watched so far, that uses simple normal day-to-day language, examples WITH VISUALS to help us understand. It's easy and everything makes sense. Thank you for being so clear and explaining everything step by step, you are an amazing teacher, thank you!!!!
@Science Revolution who asked
Watching "Interstellar' sparked my interest in actually learning what I hadn't learned in school.
Nice
Never took physics in high school and I went to college as a chem major in 2015. They made me take advanced physics my first semester which I failed horribly. Ended up dropping out a month into the second semester. I wish I had this video back then. Your instruction is amazing.
kinda weird if ur gonna take chem but not physics like wut
@@uchiharat2922 Depending on where you are people usually only take 2 out of the 3 sciences, and Chem and Bio is an extremely common combo
@@tensaren how do u know they took bio
@@uchiharat2922 yeah you right lol
They fu**ed you over. Most people would fail under the same circumstance.
Usually a different way of thinking and the assumption that you understand the math. Just by not understanding something like fractions or trig you can be lost. Since it was advanced physics in college I am guessing you probably used some calculus so that makes it even more difficult.
Taking physics this upcoming fall semester. Have zero idea about what I'm getting myself into & I'm shaky in math. I figured I'd get a head start. Thank you!
I too am taking physics and calc 2 this fall… gonna be a roller coaster ride. Good luck!!! :)
@@doanerific9908 LMAO me 3. Good luck yall
@@Awesome999ification I've got a physics exam TOMORROW and I am not prepared, I'm watching this, and my exams is mainly about moments, principal of moments, momentum etc, will I fail? 😃😃
@@fmunited2487 how well did you do? Lol
@@MaruSurfs it's probably not a good sign if you haven't gotten a response yet...
Haven't even watched the video but I already know that this is gonna save some people.
its the same video uploades 2 years ago
Honestly, I'm not even in college or uni. The physics teacher at my high school basically convinced me that his class was too hard for me, and that I shouldn't take it. (clearly he was too judgemental to have any business working with young minds) so I never really pursued physics until recent years, studying and experimenting in my spare time. I don't mind if it's a re-upload of an old video, I'm just glad to see he's active!
@@masternobody1896
So! What’s wrong with that?
Bet there are a lot of people who is glad of it.
But thanks for the observation. It is good to know that also.
@@thecrazyfarmboy Your high school physics teacher sounds like an insecure psychological mess of a human being. The man obviously feels inadequate about many things in his life and needs to project feelings of inadequacy on to whom ever his position allows him the apparatus to do so. Sounds like passive aggressive bullying to me. I'm glad you didn't listen to him and started pursuing this knowledge on your own terms. Much respect!
@@demonlord8398 Thank you!! Much appreciated
Thank you for this, dropped out of college but I'm now getting more interested in science and physics. Videos like this are a great help getting back into it! Thanks for what you're doing keep up the good work!
I wanted to study physics and mathematics but I struggled a lot with understanding the basics of it and gave up, but these videos have been helping a lot. Thank you
I don’t know a thing about physics and I’m not the brightest when it comes to math but something about physics that really catches my eye 😭
same homie, same TwT
Same. I feel passionate about biology even though I dislike memorization.
Same!
Same 🙂
I am literally 12 years old and I can understand his content better than all of my books, textbooks, teachers, and schools. This guy is truly a legend.
I am 9 and I can understand this
I am not even in my womb yet and I can understand this
my parents arent even born yet and i can understand this
No one exists yet and I can understand this
I am T-Rex and i can understand it
I always try to study my lessons in advance to try and speed up my learning process when in school and your videos make it all the more easier! Been following for years now and your videos are still yet to fail me. Kudos to you, sir!
I was always afraid of physics. Now I’m learning. This is awesome.
Hello
wait until you found about calc 2 and 3
Physics killed every one you ever knew. Be afraid
Same 2 you
It's awesome
This person delivers lessons perfectly and smoothly like a programmed robot, if teachers were very competent like him, people would love science and consider it just like a cake eating
but i dont like cake.......

@@deyvidvalente1 who likes icing🥴
Im 13 and i really want to learn but im a slow learner so as my teacher teaches i ask question after question and i rigorously take notes but i never seem to be able to wrap my head around it so i have turned to extra steps in learning and i found this which allows me to rewind and take notes at my own pace, thank you man
You're 15 now
How did it go?
You're extremely unbelievable! What you captured in 20+ mins is mind blowing... I love you
Can I just say that you are a KING you helped me so much last semester with my Algebra class and now I am running back to you for my Physics class lol. Seriously you helped me so much and I wanted to let you know you have a new fan and supporter! Keep being awesome man "claps"
You sir, are a life-saver and im legit crying
i have been STRUGGLING with these basics and just assumed that i suck at physics.
THANK YOU and jesus somebody give this man a medal
For all those watching these guys videos to become great in any subjecr or for an exam this guy is just a saviour. I hated physics all my life but I wrote the medicine competitive exam without any knowlegde in physics 1 month before exam . Then i studied entirely with your vidéos and i passed with the physics scholarship. Really may god bless you so much guy. you provide such help to peoples that you cannot even imagine 😫😫
this video is one of the most important video in order to understand physics, u cant understand physics without knowing these basics. this video is a life saver and properly taught w out any complications unlike other professors or teachers, keep up the great work sir
THIS IS A LIFE SAVER!!! I'm skipping a physics year next year and I'll have to do it throughout the summer this is amazing!!!
Yayy you're back! We missed you.
Hope you're doing good. Thank you for helping loads of students, including me. ❤
You are amazing! I am a homeschool mom and my 11th grader is taking physics this year. Thank you so much for making videos that can help me teach him! You are so appreciated! I would recommend your videos to any homeschoolers.
The way you execute these lessons are second to none. Thanks, mate, for such detail and clarity.
You are very active now, and we love this💙
the dude has got me through my chemical engineering degree
فديتش
@@rafisanders he might be one of the only reasons i graduate from highschool
@@rafisanders I am an engineering student as well and he made it so easy for me to pass calculus and physics classes
Stop reading the comments and watch the dang video
OK!
im teaching myself physics because i’m bored 😞😞
Same
Physics can be fun to learn
im doing it because i never took it and have a physics class next year😓
@@KMondy93 It’s like dealing with a second math class
@@KMondy93ME RN!!! i can’t wait tho I wanna be an astrophysicist so this stuff excited me lolol and i wasn’t allowed to take it before but now i can and i’m PSYCHED
I wish I paid more attention in school because the older I get the more interested I become in physics and how the universe works. I’m 23 and have spent more time in the last 6 months learning every little bit I can about physics then I have in my whole life in school. It’s absolutely mind blowing when you really get into it
this video will go on to help millions of students in the following 10 years- fucking legend
This guy not only knows everything, but he can also teach everything so well. Keep it up and thanks for the hard work! :)
i dont know what kind of sorcery or whatever this is but this channel rlly helped me a lot. i could never understand a thing from my teachers but here ??!! in less than an hour ?!?!! DAMN JUST HOW COULD I LIVE WITHOUT YOU.
I had to take physics in the middle of my term 2, this video has been a life saver, thank you so much.

Hey a quick question....im 27 and i wanna know if i can still study physics...but im from the caribbean. Please some answer...because I really wanna be a astronomer...but I gotta study physics first in a foreign country
@@enjoylife1110 yes you can
i also wanna be an astronaunt man and im 13@@enjoylife1110
From somebody who just wanted to understand what velocity is I found this video very helpful. Have a much better understanding of physics, well done.
I'll have to say that your explanation is very very good. Every thing is explained so slowly, properly and clearly. Thanks a lot for this.
Homeschooling has been quite the stuggle for me lately, but when i found your channel, i've been having alot more fun learning, i truly thank you.
Im studying this video so that my Rec Room physics-based inventions are that much better. And they will be! This contains incredibly useful information, It's straight to the point, and you know how to work a mic. THANK YOU.
Thank you so much for this intro. I'm taking this class in the fall and I do not want to start off not understanding the material. You are the greatest......
My notes were all scattered and because of this refreshment , I'm getting new book. Thanks man👍
Dude, you are the best; I was terrified of my Physics class because I suck at Math. However, you have made it so much easier to understand Basic Physics; thank you so much...
Thank you. This was very easy to understand and it’s restored my faith In my soon to be 63 yr old brain. 🤯🤪
I’ve paid for online courses and gotten no where and lamented the loss of my hard earned money. This video, which was free thanks to your time and generosity has been great. 🥂👏👏
the lesson that I have waited for thousand years now is here thank you so much
My old school didn’t teach us the traditional physics for three years and now that I’m changing schools it’s very difficult cause They said they would put me a year behind if I didn’t know physics, this really helped and I hope I do well in my test so that I can stay in my grade, thank you !
Thank you good sir for this video. I have been so confused this semester. Your explanations of the basic concepts was just what I needed :,)
this is one thing that will never stop amaze me.
How is it that a physics teacher with years of teaching can fail to make me understand physics or keep my interest (and underline *keep* he didn't have to give me interest he had to keep it)
while the average internet teacher (be it on youtube, kan academy, or any other teaching platform) can increase my interest and make me understand complex things easily?
and lets not forget *for free*
luckily not all teacher are like that but lets be honest, we all have "that one teacher"
Amazing video!
Oh lord you're back. Thanks for making another one of these.
I missed all of my first physics lessons due to life and found all of them here summarized in 55 min and now I can even pause the teacher to take down notes. thanx
I felt the “pause the teacher to take down notes part”. Coz i be doing the same😂
@@ntokozomokwane1329 yea lol
Excellent video, and I really appreciate the timestamps!
Thank you for your channel! It’s amazing to realize what one forgets from 6 years of university. Well done!
You really are out here saving me from failing during quarantine! Thank you
Hey man, I am in a coding academy, and we are about to create games, and my teacher said I need to learn physics, and you covered it ALL. You need to be my teacher. Good job (:D)
Nice
we’re having physics third quarter in science, so i got really excited and decided to do some advanced studying but nobody would teach me because they seemed to hate physics. i’ll be able to answer once the lesson comes up, thank you!
This is the BEST class I have ever received. When I get paid I'll be your patreon.
I literally had a very hard time studying physics but this helped me sm , thank you
Very impressive, I have gotten what I'm looking for.
Thank you sir
YOU ARE AMAZING!!!! THANK YOU!! I was mortified of physics (never took it in high school and then had a few bad experiences) and you explained these concepts so smoothly. God Bless you!!! 🙏🏽
Just listened to my first Physics 1 lesson, and I didn't understand anything, and neither did anyone else, this is gonna be a life saver for when I need to study.
This method of teaching is amazing. I dont know if its something intrinsicly american but, here in Brazil they teach physics in a confusing form. I´m enchanted with this simplicity. Thank you very much!
I know, he is not from America, he is from heaven 😇😇😇😇😇😇😇👩🎓👩🎓👩🎓👨🎓👨🎓👨🎓
yeah its really easy to understand what he is talkin about cause i'm just a primary student and i was bored after the major exams nd started learning physics .have a lot of interest on this subject.Literally a free professor.Thanks!
I trust you with my career
Starting learning maths with you and it’s amazing
Now physic and every other
God bless you
I am so happy that you are going to teach us physics
Keep going you are so good ❤️
Excellent basic physics class. Thank you so much to sharing your knowledge of physics with us.
You are really the best! I bet none of your pupils get below 90% ,if one of your profession is teaching.❤
never ever learnt physics in my school i had to learn it for a college entrance exam and this video basically summed up most of the major things with ease and ngl it was, totally recommended and thanks very much to the creator all respect.
The problem with my prof. Are that they might know physics but don't know heck about how to teach it. They even themselves get confused sometimes about what they just wrote on the board. Well, this guy know both physics and teaching. Love you man thank you❤❤🎉
Right. Knowing and Teaching are two different things!
@@sharondavis3535Chris Evans home future would love it if you think you now would tomorrow people soon now my first day back next week we will talk back next week we will do that now that you can find out now if you be free and time we go back
You are a science communicator hero. Thank you so much.
Clear and concise. Not an easy work, but the ability to put big ideas in few words made it look so. Thank you.
I finally don't struggle in Uni. I saved this playlist for my upcoming exam after acing the chemistry exam (I hope) which I also do study with this channel. Idk how but I'm from germany and the german youtubers don't explain that well like it's always something missing and than I'm left with questions but in this channel he also do explain why we do what we do so everything makes sense hehe 😅
JG knows everything this man is fire 🔥❤
indeed
Thank you very much, sir. I'm studying to be a physics teacher, I love physic but I'm no good at it, I love experiments and when the problem came from physic, I would love to solve it. That's why I'm truly want to be a teacher to teach people. This video helps me a lot since I can't found a book or a website that can show me all the basic in physic with text and demonstration, it's always shown so little on these simple, basic makes me can not fully understand. And again, thank you for making these videos, I'd love to see more of them. All the best wishes to you.
Sorry if my English was bad but I have tried my best :D
Check out a few apps on the Google play store. Although they are in english they do have good sources to learn from. I've also heard a lot about MIT open courseware, I'm just getting into physics too lol. Look online for a class syllabus and try to follow that at your own pace.
I think that it's a great thing that you have an interest in physics. You'll need to try a bit but I'm sure you can do it. Good luck on your journey
I'm glad to know that a lot of people here found this content useful. I just want to add that Physics describes physical phenomenons, that means the real world, and we use math only to calculate variations on them. For example if you walk in a circle, your distance will be calculate using the formula for perimeter: 2πR and if you want to calculate displacement, that's is even easier, IT IS ZERO because you can walk as much as you can, in any shape you want but if you return to the starting point then your displacement is always zero, YOU DIDN'T CHANGE A BIT. The moral is LEARN CONCEPTS FIRST THEN USE MATH TO DO CALCULATION. HAPPY LEARNING TO EVERYONE.😃😃
I just found this channel, what a gem of information thank you!!!
i thank thee, as a student interested in taking physics, this has helped out a ton!
wow I didn't know, I could learn so much from 1 sitting. Always saving my life! Thank you organic chem tutor. Atleast now I appreciate physics because I can understand a bit of it. Will do problem sets later to review!
Don't you sit in school?
Seems fun
@@cutiemeowie8352some schools don't teach it like this and every learns different
Wow, just wow, next year I'm learning physics in grade 7 and I gotta say I'm impressed I've always wanted to learn physics but since I was so impatient till next year I decided to watch a physics video and I understood everything!!
Good job
so im gonna pop on here and comment now on a different video, you have literally been saving my life for YEARS. i just started physics this week and for whatever reason the first lesson made absolutely no sense to me, like i missed a prerequisite nothing made sense that he was talking about. And the first 5 minutes of this video are helping me connect all the dots from the things weve talked about during lecture. im still panicking but i feel better now knowing teach physics too lol
University professors on their way to get paid while this guy gives you the class for free..
JG, do you have any plan on a live streaming? I have tons of questions on how you have learned all of the physics, chemistry, electronics. I am still waiting for your live show
Dude you need more views, this would seriously save so many people, thank you so much!!!
I love this man. That why I buy whatever he sells. Please show your support and keep this man helping all of us!!!
Aww man I needed this video Last year
I watch this to relax thanks so much. Physics makes me feel safe and comforted. Thanks
I didn't have physics in high school and wanna study CS in uni and i have 1 semester of phyiscs, this is where i start my preperation, thanks for the free video!
Im taking honors physics this year, I'm a freshman and it was KILLING ME, thank you for being clear in this video!!!!
Very well explained ! Thank you ❤️
I’m studying for my science teacher certification exam and this is such a helpful review video!
Good luck!

Luxury lecture . Alot of hurduls cleared in this video . Thank you sir.
this will save my life and I haven’t event watched it yet
These are the lectures which students needs to clear their doubt 🙏
Million of thanks for making this channel and especially for subtitles
Thanks for the video. I forgot or didn't learn this well enough. My life now has a lot less options to fill up my time. I plan to learn more than participate in activities I physically can't, financially dig deeper in debit with, and need more than myself to do. It feels like a blank check for me to wonder about, use these understandings in theory that a pen pencil and loose leaf paper and similar tools for a good use of time. I do really appreciate the help you can consider me if you doubt ever about was anyone truly helped.
I’m so happy I found this video!!! I take physics next term and I’m so not ready 😩😩 I have to learn r because I’m applying for the Sonography Program so it defeats the purpose of going into Sonography if I can’t understand Physics
