30 minutes with u more efficient than being 2 hours in the class...this is what we called a TALENT
facts on facts
This is what everyone says. I suspect the majority of teachers are capable of this, and we just dont usually pay attention in class as easily, which is why we resort to this channel

@@chiralanomalous2904 maybe, but unfortunately some of us have teachers that are just really bad at explaining
@@chiralanomalous2904 especially in quarantine, but yeah he’s definitely good at breaking down the lesson
People love this channel because he tells us what we NEED to know. No beating around the bush, no extra fudge, it's just the main thing, presented in a form you remember.

Don't go to school 😂
I want to cry tbh
Lmao
same hre
same bitch. cant handle shit especially the projectile motion 2
My exam is tomorrow so same
Its not that hard
i got a test in 8 hours... let's make some magic happen
EDIT: I got a 90 :) Thank you brother.
David Sheppard congratulations
congrats

jæ zup i feel u
same here. This is the motivation that i was looking for. thx man
this man is a genius. physics, organic chemistry what doesnt this man know
I consider him absolutely unmissable! I use his youtube page a lot to educate myself, increase physics enthusiasm and get to know the real world more.
You forgot to mention Calculus
he also did some math, especially statistics.
Also bio.
you. he probably don't know you.
bruh the first 6 minutes was so much more helpful then three of my 50 min physics classes
lol do u hav tsai HAHAH

what is the difference between 1st and 3rd case?
@@nurfaqihahridzuan8870 1st case the ball just rolls off the cliff, but 3rd case the ball is thrown up and then goes down.
You must be going to an elite school, all that knowledge compressed into one brain.
i'm an engineering student and i can honestly say you have been my teacher ever since i started school. Thank you so much for making my grades high
Hows engineering??
@@aurumstinger4479 Garbage.
Man thank you so much. You’ve helped me a ton in chemistry and already in the first few minutes of this video you are way more clear than my professor and textbook. God bless man, I hope you have a ton of success. Literally one of the best tutors on TH-cam
I had a hard time understanding this because we have online classes now and me and my teachers are still new to it. Thank you so much. You teach very well!
You have been helping me with Physics, Chemistry and Maths since high school and now college. Not sure how I would have passes without this channel.
i really love his voice it's calm and soothing
I agree
i mean mine is too ;)
@@Deimra wtf
I mean She wants me
lmao
You are actually the best physics teacher I have found in years. Thank you!
I have a test in 5 minutes and i dont know a thing about projectile motion
Monka S I have one in three hours and I don’t either
@@ru.e1072 i got through it with a 86 though just try and memorize everything
@@anthonybarr301 you're so lucky lol
hahahah me too
Brooooo 😜😜😜
You are really a genius man . I have been struggling to understand projectile motion for weeks and now watching your video I have completely understood it. Thank you verrrrrrrry much..
I really wish i could give you a hug right now. You're the best teacher I've ever had. You're so good.
Whoever u are, may god bless u with everything u need, and i effing love ya, this is amazing. I cant stress how grateful i am❤
Mr JG I cannot let you know my happiness after going through this video of yours Sir.The thing which I could not get into my head for the past 1 year, you got it into me within 1/2 an hour.Respects for you sir.
your videos are simple,good and well explained . i love when the small things you explain which i forget.
You make it all simple , A+ student , Thats what you made me
For those that want some practice on this topic with real life problems, my newest videos guides you through such exercises step-by-step. It might help :)
th-cam.com/video/qyIHtQ5NQ28/w-d-xo.html
So helpful, thank you! You make it so easy to see where the equations were derived from, which is something my textbooks don't do. I have an AP test coming up, and with your videos I grow increasingly confident!
It really bothers me because I use initial velocity, u, instead of Vo
It really bothers me when people use u, instead of Vi
I used to use u when I was in Jamaica
then i came to America and my physics teacher uses Vo
consider using Vi, Vix and Viy are more clear to me.
@@dervettehenderson9532 Same bro, moved from Trinidad to Canada and i had to switch from U to to Vi
Yes yes it does
Everybody talking about college while im 15 year old starting 10th grade with this topic im Ethiopian by the way
Omg sameeee
me too wth
Im in 9th grade with this topic smh
@@TheChosenOne1_ I Hate physics!
u better learn it well!
u r gonna deal with it again on grade 11
If you want to know you've mastered projectiles or want a good head banging challenge try to solve this: th-cam.com/video/g4fgQN9b0no/w-d-xo.html
Thank you for much!!!!
You saved me from my Chemistry course and now Physics course. I haven't taken any Physics classes for 4 years since I finished high school. I was completely lost in class because my Pro really didn't know how to convey the lecture (He's good but only for smart students). However your videos really saved me. I didn't even know a thing when I was doing those types of problem in 1D dimension before I discovered you had a video about this. I was able to finish all the problems in the video!!!!!
*BIG THANKS*
For me 30 minutes with you is more efficient than 30 days in the classroom. 🙏
I prefer your videos over a textbook. I learn more this way. Thank you for the great content!
I’m watching this while taking a shit. The grind don’t stop even even if you constipated
My channel was started by your inspiration sir and today I'm a huge pro at this.. Respect ❤️💯
This guy is just a miracle
Thank you very much for your work... you’ve really helped a lot🤝
thank you for your great videos, they always come with the clutch, anything that I don't understand, I look at your videos, and it becomes effortless.
keep it up!!
I'm always looking for tutorial guide and reference since I was under modular study. Well I'm thankful to mr. JG, all of your tutorial guide makes my comprehension better🤗.
Heads up! When he's reviewing the equations you'll need for each problem at the end, let me point something out to you. In problem 2, the symmetrical trajectory problem, he says that the final speed is the same as the initial speed. He writes Si=20 then S=20. However, keep in mind that this is SPEED. More often than not, you're dealing with VELOCITY, which can be thought of as the vector version of speed. In this case, Vi = negative V. They'll have the same magnitude but OPPOSITE direction.
So 0 velocity? 😢
good call mate
this is the first time ever I find his video not to be help full. I want to cry so bad rn. I was only shown 3 formulas and this guy brings up 5 formulas so I am even more confused now lol
In the past 2 years I have tried to learn this topic 4 times...and I had never understood it till this moment ..I am amazed by how easy this is now. Thanks!!😭😭😭
thank you so much for making me understand the concept behind how we got these equations
your voice is perfect, I like it and actually, I like everything about your videos. You are AMAZING!
aw
Thank you so much for being an excellent teacher. I'm trying to learn this to teach my daughter.
I literally feel like crying right now you're a lifesaver. Thank u so much :)
Very helpful video: clear and structured. Thank you!
nao tenho palavras certas para agradecer este magnifico professor que talento em explicar
que DEUS te abençoe senhor. parabens
Midterms tomorrow haha...thanks for saving my life!
Thank you!!
All the physics teachers in my school left and now we get a test we know nothing about from our long term sub.
I can finally pass!
Love this ♥️....I really struggled trying to figure it out using a textbook. I never imagined it could be this easy.🙏🙏🙏
I come to your channel before reading the handouts my teacher gave me. That way, I will understand what I'm reading better. Thank you for helping me for 3 years already!
why are you such a legend you're a chem teacher yet you can teach physics just as well
and calculus or in short math itself
Really?
Thank you for the wonderful tutorial! Beautifully explained!
i have been following this lecture my computer is full of his videos serious you amaze me in every module that I'm doing even if i miss the class i will still come to learn to your lessons thumbs up ....... give us more
Thanks for taking the time to this.

i so wanna hug you man, thank you so much, just saved my my text grade!!!!
this guy is so good, i would prefer him to teach me. just 30 minutes man!!!!i'm already feeling this good i have no confusion with this guy .... well done man please continue doing more vidz
This guy restored my confidence. God bless you.
i got a test in 2 hours lets see what i get
EDIT: even tho i studied i still got a 50%
What grade r u

hardest lesson ive ever took in physics
ps: i didnt understand shit and i lost hope
Same
What do you not understand mate, i can try to clear out your query

I'm honestly struggling to my physics subject and this could be a great help.
Hey ,
Your video is very educative
In fact j understood much better than lectures in class .
Your pace is perfect and concept excellent ....
people in the comments section be crying in college while im crying in high school
im asian btw
yeah i’m a senior and i genuinely don’t understand anything. i wanna give up
#1 nice profile picture, I see you are a person of culture
#2 bro same I am dying but somehow miraculously making a 99 without knowing anything
Try being a sophomore in highschool & learning thisss
Senior high studnets 😫
Junior in high school
Halo.... sir u are such a great teacher.... easily you explain hard topics....☺
I cannot thank u enough for this video. This channel has taught me more than school.
Wow ... Understanding in no time .
This guy is a genius.
I’m literally crying just simply watching this
ugh mood
This is my favourite part of physics so far tbh
was crying while studying this lesson for a quiz. After watching this for like 10 mins only I already understand everything I didn't. Seriously, thank you. Lets see how much will I get on my quiz
Boy you are awesome. The way you explained every thing was excellent.Keep it up.
bro you are a life saver
Whhoooh thank you so muchhh my life saver my herooo ! I love youu so much and I love your videos the are the best I wish you where my teacher 😭💕💕💕💕💕💕💕💕💕
Meeeee toooooooooaaaahhhhhh😭😭😭😭😭😭😭😭😭😭😭😭😭Whyyyyyyyyyyyyyyyyhihihiheeeeeeeeeeeee?????😭😭😭😭😭😭😭😢😢😢😢😢😢😢😢
Thanks man, I was failed yesterdays quiz, it sucks me,but now I come back strong.
My teacher did not teach us about Any of these equations, we are given values for v and theta and we have to plug them into the original 5 kinematic equations and solve, which often leads to negative errors, or just wrong answers. These are just SO much more helpful, thank you so much!
you will never know how much i love you. gives you a lot of virtual hugs
Great tutorial. Thanks
20:05 I noticed that the formula you used for tB->tC is the same as the formula for the height for case no.1 (2:45).
I'm just wondering why you can use that formula because in Case 3, from point B to C, the initial velocity isn't equal to 0 like it is in Case 1.
So if use the same formula we derived from (d = Vo*t + 1/2(at^2)) we will no longer cancel out Vo*t because in Case 3, we have the value for Vo already.
I am aware that your comment is 2 years old, but for new viewrs who might have the same question: While it is true that Vo is not zero, Voy (the vertical speed or Vo * sin) will be zero after we reach the maximum height, as the object is no longer moving up, so for the distance B to C we can use this formula (2:45) to find the height. Meaning, this case 3 is like two cases combined.
Wow, great video. Just what I need for my class.
Beautifully presented and explained! Thanks.
I did this back in 8th grade, and I feel even more stupid now in high school, not knowing 100%, going over the same stuff as I did back then.
Next video’s gotta be reviving your asian genes
dapz??? why are you here??
@@Human-santhats what im wondering 😭
I got a final mark of 97% because of your videos, thank you!!!
i've come to the point where the two reasons i am going to the classes is so that 1- i am not kicked from absence and 2- its dedicated time to study and since the professors suck at their job i just watch this and use some other sources to study myself in class lol and it works like a charm. thank you for existing.
yo thank you so much you saved my life hope everything goes well for you
Video is good but it would make make it easier to understand if you used u for initial velocity and v for final velocity as it gets very confusing
Me: why did i take enginnering 😭😆
dude we take that shit i junior high school
@@ninaalmola6409 lol true
Nina Almola exactly why I'm here
@@ninaalmola6409 😆
lol saem
You are my Math, Physics & chemistry teacher😊😊
Your class is op level
Better sit down and just listen to this genius!
who else is preparing for World War III and learning it for their 120mm mortar ???
Hey I'm from India! Is there any standard formula for velocity while striking the ground in a proper projectile motion?
Thanks very much for your outstanding work. In class l don't understand anything. If being in class is part of wasting my time. I always understand yo work. Good explanation. Thanks a lot keep it up.
tomorrow is Exam and I learned nothing from the lessons, this channel is my only hope!!
Ill update tomorrow
Bless me luck!!

What did u get
Are you still with us or did the infinity stone flip flop dust you away...
Hey what did you get
@Swiperior Goodluck bro, hope you do good
To apply the equation dy= 1/2.g.d^2t, dt has to be the time interval between the instance of starting falling ( where viy=om/s) and the instance just before the ball hitting the ground ( where vfy= the negative of the maximum vertical speed), but practically we consider ti is the time the ball leaving the cliff, which means the time consumed horizontally is misleadng the resultant of the equation ( y-displacement or height)
Thanks so much for your videos they are the reason i am passing my ib hl physics classes!! amazing work
I'm too dumb for this. I wanna cry so bad
im crying already :')
The projectile has maximum value of time of flight, when it is projected at an angle of projection?
90 degree with the horizontal
