Ok this literally helped me with my hw. I had no idea what my tr was saying.

THIS HELPS SO MUCH I FINALLY UNDERSTAND

I've been trying to understand this for 4 months. you've cleared it up in less then 10 mins. I'm so grateful.

searching for weeks to find the ONE helpful video and i found it, great because now i can pass my science class semester!

BRO YOURE SO GOOD THAT IM FINNA TURN AUTISTICCC HOW TF DO YOU EXPLAIN ALL OF THAT IN LIKE 4 MINS WHEN MY TEACHER COULDNT EXPLAIN IN 6 HOURS

It covers everything in a gcse portion...thank you SO MUCH!!

Man thats so easy understandable and will help me in my exams

When your teacher keeps talking whilst your watching the video

Simple and direct. Thanks

Great video! This topic is very confusing so thanks very much!

I understand but it won't be precise. As for the tangent, we won't know how long we should draw. So it will only come as average?

THANKKK YOUUUUU SOOO MUCH I AM SO MUCH FICKIHG STRUGGLING WITH PHYSICS ... YOU HELPED ME AGAIN COGNITO MAN

brilliant you kept it short and covered everything we need to know

Thank you so much have a physics test tomorrow and this really helped!

I’m on a zoom call right now while having to watch this, I can’t focus lol

Thanks this helped me in preparation for exams

Thanks for this

THANK YOU SO MUCH!!! I have physics final tomorrow and this saved me

CHINNIAH SIR IS THE BEST SIR IN THE WORLD

I did my mocks and hopefully went well cause of this

if only all teachers were like this.

That made me understand it very good (the best)😊😊

thanks a lot man this helped me alot

I love this channel!

Is a straight line and sloped line the same? Becuase sloped line shows movement and for a sloped line m is shallow

Your explanation is great, wish my teachers explanation was like yours

Thank you man 😎😎🥳

Omg soo useful vedio!!! I was literally searching for the best video, and now I have it💜

If it was in hours (let’s say an aeroplane was flying at 380mph for 9 hours and you would need to find the distance) would you make the hours into seconds so would you do 380x540?

this helped me SO MUCH in my ks3 assessment THANK YOU!!!!

THIS HELPS SO MUCH I FINALLY UNDERSTAND °THANK YOU

This video was very helpful, thank you 😊😊

this helped me so much cause in cgp they write it so unclear like i didn't even know what a tangent is anyways thanks (ps the world would be in shambles without you)

Literally you helped me in every paper and I scored A* grade in all!

Thanks mate i got my gcse physics on the 25th of may

so for finding the tangent on a line, you can pick any points? it doesnt matter which 2 points you choose?

An incredible video, surely, and I loved it. However, I still have doubts regarding the concept of tangents, and their applicability, and hence request you to clarify how it is used with a non-uniform gradient. Hope you'll be able to clarify that

Thank you sir it makes me easy to understand the concepts I hope it may helpful in my neet UG

🤗🥳 you are Amazing!

The problem is that i dont know English so much but I love science physics especially about the space

Epic!

3:14 onwards is summary

Thank you so much ❤️🧡💙💜💚

Grateful!

But doesn’t that mean that your speed can vary depending on how long you draw your tangent?

Literally the basics of calculus 3:00

best than our teacher

When you have a doubt in class😮 Teacher: how many times i am gonna taught this to you???!! Random man on youtube : i will teach you my son/daughter By the way this video helps me so much in exam that's why i am writing this.😅😅

Watching this at Morning, hour before exam.

But how long should be the tangent, how can we know the size of it before making it to find the speed for a curve

im on science class rn im watching this lmao help

THANK YOU

So a straight line is when the object stops. A diagonal line going up is acceleration, and a diagonal line going down is deceleration and a horizontal line is when the object is stationary?

❤❤❤❤thank you 🙏 very much now l have an idea about distance time graph please teach me all about graphs a video please

Thank you

Does the curve in a distance-time graph represent changing or constant acceleration?

that is very good

Bro im literally seeing myself in my graduation attire right now fr🥲

I understand these things well but come here for better understanding and great drawings for my notes... new subscriber

I have a question. In my textbook (and class) there is a different method of finding the speed out, but I don't get that one either. It says speed = gradient of distance - time graph. And then there are four steps which tell me to find the straight section of the graph and draw horizontal and vertical lines to complete a right-angled triangle. So can you please explain this?

help i have two questions how do we know what length to draw the tangent? and when finding the gradient from tangent like why at 2:42 the blue dotted line why did it start from where it did on the tangent line why not from like the ends of the tangent line? is there a specific reason why rose blue dots to find distance started at those parts of tangent line?

best video for kids

thank u so so much i was abt to fail physics until i saw this vid

What's the length of the tangent supposed to be? does the length matter?

Still using these vids to this day 😂

This is worth 5 science lessons ong

This was so useful, but I sometimes find the sound of his voice fades and some words are difficult to hear, not sure if that's just me!

Is the speed time graph the same as the velocity time graph?

Why is the gradient 0 at the stationary point

Very helpful thank you so much

make more than ever

can u please help me with the tanget part

ik Its too late okay but .. alot of pple in this comment section seem to be understanding what is done here but I can't really understand the part where uu calculated the 'tension' (if im correct with spelling) around 2:30 ...plz help 😭

I still didn't get it Like won't the speed cart bcz of the variation in the tangents length I mean it depends on us where we mark .

I am still confused and have some questions.

what does a square respresent?

This didn’t help, I’m really confused still

The true answer YAYY

my teacher in school was bad at teachin physics. so i will only took the topic and study here

i meant it's so understanduble

HELLO

Tomorrow is my physics 7th final amd i am studying from here

how did u find the 12 for change in distance?

❤️

I just wanted to ask that is it really necessary to draw a tangent bcz we can also find it normally by looking at the graph??

How much long enough should the tangent be

gosh i had to learn this at grade 7 bruh 😭

demostration

decweaseeeee

i dont understand the exam questions that distance and speed time graphs have, the questions are worded differently and confusing

Anyone els here from science at churchill

igcse board brother wrong title

wait isn't the change in time is equal to 4??

E

This helps I understand now

i have aa end of topic test so this is gonna help me for tmr skl

0:56 When the accent is too deep

I have exam tomorrow and ididnt understand 😭😭😃😃

In exams they ask u what is going on with a part in a graph, that is is a combination of acc and dec, it is pretty sad
