When do we say that an object is accelerating? What happens to the velocity of an object when it accelerates or when it is in motion? Is acceleration scalar or vector? or What is acceleration?
Watch this video to know the answers!
Acceleration is the rate of change of the velocity of an object with respect to time.
Acceleration (a) is the change in velocity (Δv) over the change in time (Δt), represented by the equation a = Δv/Δt.

One question🙋:- that why we use velocity in acceleration instead of speed? We can use speed and if answer is for direction.. Then what is the use of direction in acceleration
If change in velocity per time is defined as acceleration then what defines change in speed? Please reply

Please explain why this channel is better than my physics teacher please.
JaylindenXX because your teacher is paid by the government
Lol
yeah
@M Detlef My physics teacher is an old man
This is multimedia
why i gotta spend a whole week studying about this when she clearly made me understand in 5 min
Same here
if you study this for a week it means you're stupid lmao
@@elgoblino7549 You're fucking mean.
@@TastyChevelle lol who tf studies what is acceleration for one whole week? 🗿 Anyways sorry I guess
@@elgoblino7549 Maybe for a test
Our understanding of acceleration is due to the work of two great scientists, Italian physicist Galileo Galilei and English physicist Isaac Newton.

Ok👍👍
Speed doesn't kill you, it's the acceleration that does.
true😅
Thank you so much I love your explanation make more vadio about this concept ok
True u play roblox right me to
Yo I luv ur name u bloody legend 💯
Idek why I'm laughing-
I used to think of acceleration as something I would never understand despite of my physics teacher all over us to understand the concept, but you have helped made a big change
Just tell me why this is soo understanding and I can't understand when teacher explains 5 times👩🏫❓🤣🤣
Bts army?
Just because of different concepts I guess💜🖤
Omg your teacher explain it 5 times ...😑
Otaku?
i guess because it's directly shown to you practically how it can be than just explaining on board .
After my recommendation my teacher has subscribed to this channel for clearing his doubts 😧 😂
😂😂😂😂

I wish you were my physics teacher......Thank you soooo much for this.....You are the best 😀👏👏
You deserve more than just 1.41 Million. If I had the power I could have made it 100M
This channel defines each and every single point so beautifully, which make us understand better. I wish that channel whould post more videos.
Wow thank you so much!!! I was stuck on my physics homework and watched this and then found it easy..... THANKS ALOT 👍👍👍👍
Am I only who is watching this video in 2024??
😂😂😂😂
No
No
No
I watching for 9 th class
Hats off to your team!!!
I watched so many videos and didn't understand velocity and acceleration and luckily is I would say fortunately I got ur video and it cleared all my doubts..
Thank u so so so much 😁
Can you please start uploading videos on the topic of astronomy where you will explain about the cosmos,black hole,neutron stars,general relativity etc. in a simplified manner.
I changed my comment so the replies make no sense.
Same and I still didn't understand the concept of acceleration until I discovered this channel
REALLY ,TEACHER NEEDS ONLY MARKS IN EXAM
Even in the US there is this problem in education?
@@humbleandsimple7903 yes , in many schools.
Now all the students are facing this problems only .what to do in front of this stupid society?
Wait, does that mean acceleration kills a person that jumps off a building? Or im just dumb?
Best thing about this channel is that it gives you knowledge with your visualising surrounding
Hello Don't memorise, I would like to say thank you to all of your videos I watched as it help me to pass my licensure exam here inn the Philippines. I am now a llicensed Electrical Engineer. Thank you so much and Godbless.

Ddj bro
it's really magic all things she explained very well and fast.
It's really a genius.
True...
I like your vd because you come direct to the point and your explanation is wow👍
Exactly
Why velocity changes when it is travelling with constant speed in specified direction
can someone pls reply to this q.?
Velocity refers to speed AND direction. Because the direction is changing (despite the fact the speed was the same) the velocity changes.
While moving on road you can't move at a normal pace you have to move right or left to reach your destination and for that you will need to change your Velocity
Velocity=direction and speed
If direction and speed change then only the velocity can be changed.
Hence, the question is wrong the velocity hasn't changed if the speed is constant and the direction is linear
It does not change
Excellent channel for clear explanation and nowhere I found such a good teacher
Your videos have been really helpful in understanding the concepts of both math and science. I have been desperately looking for videos on physics: work and energy for class 8. Please upload. Thank you.
Wow your explanation is very clear to the core!!!👍👍 I am able to understand this concept easily now compared to last time when I struggled a lot in this basic concept.😘🤙 Kudos to Don't Memorise channel.
Thank you :)
Thank you so much for explaining me the meaning of acceleration
My physics teacher sent me this .
Each and every doubt cleared . amazing 👍👍
This is the best explanation I've seen on youtube so far. Thank you
You're most welcome and Thanks for your appreciation. We are glad that you understood the concept. We are happy that we could help you learn. You motivate us to do better. Keep watching our videos : )
That is so sooo good! Specially this example @ 2:25 . That's clean. Wow.
What a name yaar 'dont memorise' it is the principle of mine too that is the reason why do I get less Mark's in every subjects
Same here

Muhammad Usman shut up bro every country is good
@Muhammad Usman Ok muhammad
They means dont learn force fully , learn by heart
Love your explanation..
Thank you for helping us to understand better 😊
After watching your video no one need to view books ☺️
Thank you so much. Didn't understand anything from my physics teacher and now I understand everything!
Thank you! This video helped me A LOT
Your teaching is easy to remeber, understand
By demonstrating, i can understand for next Physics class
Glad you liked it! Happy Learning :)
I wish that in online classes you will be mine teacher because the topic clears like zup❤️❤️❤️❤️
Thank you, unlike most presentations your presentation is supported by animations. In conclusion I think the direction of acceleration is in the direction of change in velocity and not always in the direction of velocity.
Thank you so much
Please keep making videos for physics
Your explanation is wonderful ,I literally understand everything thank you so much 💜💜💜
army? me too😁
I can't explain your effort in words
It really helped me ❤️❤️
Outstanding explanation ma'am....😍 First time I was able to get about Acceleration.. Thank you so much for helping me.... 😇
Very good explanation!
Nice video
I wish if my teacher explain to us like this.
Thank you so much don't memories. no words to define.. your videos help me while studying... Just not me ... Your videos help millions of people ... Thank you once again 💕
thanks for your wonderful explanations , i can literally understand everything....
awesome.... helpful

Hey!!!! You got a new subscriber 🤩
This channel is awesome. I had missed many physics classes because of sick leave and missed the whole chapter. Tbh this channel explains better than my physics tr.
Glad to know you like our videos, Suraiya ! Keep watching and learning 🙂🙂
I can't explain my words this channel really deserve lot of respect
Thank you for the demonstration. This has helpmed me move from a purely intuative understanding to a more academic understanding. I cannot ask for more from a teacher. Much obliged! Now if you help me understand how the curvature of light is brought about by acceleration, I will name my next child after you.
Um, your going to name your child “Don’t Memorise”?
Honestly, it sounds weird tho

THANK YOU SO MUCH I HAVE A LONG TEST TOMORROW THIS VIDEO MADE IT SO MUCH EASIER
According to relativity the human wont go back the car comes to him but this is also correct in physics🤯
Very good concepts..
Do more videos
i was very confused until i watched this. u helped me so much in school,thank you!!!!!!!!!!!!
This makes more sense! Thank you so much!
This is valuble for my exam
You had told better than my physics teacher so, I have a doubt my physics teacher told countable quantity can you prepare video on this please
This was a great video. Can you also talk about lateral acceleration which we call as cornering.
Literally explained something's that took me 2 hours but still confused and now I understood it in just 4.40 seconds!!
I think you accidentally dropped this: 👑
Thanks a lot for explaining the concept of velocity. It was a bit confusing that if velocity changes then accilaration or if it is not. But this video cleard my doubt. Thanks
Plz write acceleration correctly...You have misspelled it...
because acceleration is rate of change of velocity, and velocity is dist. travelled per unit time in a specific
direction
U said velocity=displacement/time but when direction changes velocity also changes,how?
i think you didnt check concept displacement is a vector quantity so it has direction so when displacement changes velocity changes
See Velocity is a vector quantity so it has Magnitude as well as Direction.We Can say that Velocity has changed if either Magnitude has Changed i.e speed or Its direction . So in the video the there was a change in direction Thus velocity changes hence It was a case of acceleration. Hope this helps
The formula that you gave represents average velocity, not velocity. Velocity = Distance/Time, just like speed. But when you want to find the average velocity, you use the formula you just gave because displacement measures the shortest distance between two points, and that's important in finding the average velocity.
To the second part of your question, let me first define velocity. Velocity is speed in a direction. So, it'll be written the same as speed except with a direction. For example: 5m/s North. So when the direction changes, let's say the object moves to the west, velocity will change to 5m/s West. If it was speed, then there would be no change. But velocity has a direction with it and when that changes, velocity changes :)
@@raisinm7494 Velocity=Displacement/time NOT distance/time
I don't understand 2:40 the object move at the same speed no velocity changes so will it not be speed not acceleration.
Its incredible. Explaining it carefully.
I am ever confused by the term velocity and accelaration but, after seeing this video I am able to solve these problems fast from everyone so thx a lots ❤
Thank you

Is it possible when the velocity is zero though there have present any acceleration?
Yes e.g. when you throw a ball up
This is not possible. Velocity factors in where one ends up. If the velocity is 0, that means you are in the place you were first standing, stationary. And, it is not possible to accelerate your speed whilst standing still. So, therefore, it is not possible to have any present acceleration whilst your velocity is 0.
If you through a stone upwards direction, at the highest point, it's velocity will be zero,however it has acceleration 'g'.
Accutally I'm dumm in physical science... Due to this pandemic school is conducting online classes. When I am in the real class only I can't understand the topic what can I understand in the virtual.....😢 These videos made my physical science easy..... Now I'm love in this channel ❤️

Really a great video, I am just speechless.... , it really makes a sense by watching this video i.e., don`t memorise
Thank you so much.....
now i know it very well
I'm glad to hear that. Thank you for sharing and thanks for watching! :)
Thks a lot
Wow
Very precise but excellent explanation. Thanks for helping me to understand the concept of acceleration and velocity
How do you make this graphical representation?
Can anyone help?
Ur teaching is ❤️ I can't even describe it in words.. Thanks a ton for such a wonderful videos 😇
Excellent ,my teacher could learn from you 😋😋
off course not
Ahmed Tarek shut up
Best teaching with best examples thanks
I was not even getting by my teacher but by you i got that
You are the best teacher
very very wonderful explanation
But when the speed is constant and direction is changing , then there is a acceleration but acceleration is zero but how ? ,
i need a video to define this . Can you give video on this ?
same problem here
Because accleration is also a vector.
Hello Priya, I understand this concept and therefore will answer your question.
Speed and acceleration are two completely different things. Speed is constant. However, acceleration is not.
Just to recap, acceleration means getting faster. With acceleration, whatever body is in motion, its speed keeps increasing/getting faster.
So let's say you are driving a car and you keep the speed of the car at 20mph; the speed is constant. The direction does not affect the speed and acceleration here, because it doesn't change anything.
The acceleration of the car you are driving is 0mph because it is moving at the same speed and its speed is NOT increasing. If the car's speed was increasing instead of staying the same, then there would be acceleration.
I hoped I helped with this and that 'Don't Memorise' make a video about this if you still don't get the concept!
My dear because speed is constant
Because if velocity changes then there is acceleration. As the direction changes, velocity will also change which means there is accceleration
Your channel is toooo great, it's small videos explain a lot of topics
How the hell are you better than my physics teacher. Thank you so much 🙏🙏🙏
