I asked the same question to my physics teacher in 8th grade , and she just made a bahanna and told a speech which was completely opposite of my question. From that day onwards since 2 years I'm searching the answer to this !😔 Thank you very much sir , meri 2 saal purani doubt to samjhane ke liye 🔥😊. !

Ohk, so for Formula of momentum, (1-v²/c²) values approximately 1 since in daily life our velocity is very small as compared to that of light and thats why we assume the formula as just (mv) 😃
After hearing Einstein equation and momentum equation both are not fully proper I am like Oo bhai ekdum se vakht badal diya jazbat badal diye Zindagi badal di
Nice sir I like this type of video Sir make more video this type . And also make long video and this type of animation. Thanks Sir for this type of vide9
Today I got to know tht Momentum is not equal to mass×velocity😅 It was very informative session And you explainee it in a very fun way!!! Thankyou sir Peace✌
Sir you are awesome and your knowledge is also AWSOME and you are so cute . Plz teach cbse 9 at vedantu in long term batch plzzzzzzzz it's and request.
SIR REALLY SALUTE TO U FOR PUTTING GARGARTUAN AMOUNT OF HARWORK AND DEDICATION TOWARDS LEARNING AND THANKS FOR AROUSING CURIOSITY AND FACINATION IN OUR MINDS..LOVED THE SESSION..
4:27 😂😂😂😂😂😂 Being serious-But sir you are our current einstein of physics! And i appreciate your efforts as you give time for the 9th and 10th channel and even work more for spectrum by vedantu channel!🙋♀️😊
Sir its too interesting, Curiosity is the key of science you proved.... ✌mine fav physics teacher, I attend most of your physic session of class 9 thank u 🤗
WOW, SIR SO MANY NEW THINGS AGAIN I LEARNED FROM U AMAZING SACHI SIR MAZA AA GAYA...I NEVER THOUGHT MOMENTUM HAS THIS FORMULA ALSO .. LIGHT IS SERIOUSLY SUCH AN INTERESTING TOPIC MY ALL-TIME FAV .. THANK U SIR FOR MAKING SUCH AN AMAZING VIDEO ... FABULOUS ACTING SIR .. HUGE RESPECT FOR U ALWAYS .. BALLEE BALLE TARRRARARRRA PEACE
Sir I have a question If we drop water it would definitely come down and we can move through an cloud like an aeroplane but why can't the water fall from clouds until it get heavier. 🥰🥰🥰🥰🥰🥰🥰
Sir ek doubt h plss dekh lo ki agar rest me body follow E=mc^2 tab ye actually E^2 = p2c2+m2c2 tha but p ka formula alag bataya apne toh kya uske according ye p2c2 pura zero ho jayega?
Does light has mass?? I think it has no mass.. But to know the exact reason , eagerly waiting for this video sir. Ye ek informative video hoga , i hope Will be an OP Video for sure 🤩🤩
sir but agar app light ko as a paticle consider karo jo displacment kar raha hai to e=mc^2 kee hisab se koi bhi object jiske pass mass hai (photon) to usko light ki speed se travel nahi karna chaiye right?

EXAMPLE 1. ELECTRON AND PHOTON MOMENTUM COMPARED
Calculate the momentum of a visible photon that has a wavelength of 500 nm.

Finding the photon momentum is a straightforward application of its definition:

#Abhishek sir is best
. 🔥🔥🔥👍
Best Movement- When we tells the formula of original momentum! WHAT!!!! And Newton Dada narrating his poems!
Amazing VIDEO SIR!
Equations to bouncer gayi but maza bohot aya sir ji. Keep it up👏🏻💯🔥😎👍🏻💜
Mind blowing! It was my favouritemost video . Please make more on advance physics.
I loved this video sir. Especially the Einstein part was OP. You are really great sir 👍👍

Sir I have a question
If we drop water it would definitely come down and we can move through an cloud like an aeroplane but why can't the water fall from clouds until it get heavier.
🥰🥰🥰🥰🥰🥰🥰
Amazing session
Us - Wow so many things are hidden from us😮
AKR Sir - It wasn't hidden u should have tried to find it
😂
Thanks sir for this wonderful information. 😊
Learnt something new from this video...
Mind blowing session with Mind blowing Sir😘❤
Balle Balle 🤗✌✌
Session was amazing I always wait for your videos.😍
My great sir please make a video on how do cloths dry on windy days
I know that :- Anything with mass cant travel in speed of light
So, I thought light has no mass
Just awesome like ever!!!!
We must learn the lesson of hardwork by Abhishek sir....😊
Wonderful information sir 😄😊
Inspiration frm Akash Gupta 🤣😂
Sir u did it so well!!!✌️✌️..
Amazing 🌈
Sir ek doubt h plss dekh lo ki agar rest me body follow E=mc^2 tab ye actually E^2 = p2c2+m2c2 tha but p ka formula alag bataya apne toh kya uske according ye p2c2 pura zero ho jayega?
Loved the session sir..... Please make a video on how does a metal detector work.... 🙏🙏🙏
very good videos......sir, please give more such video
Amazing video with clear concept.. 😍
Abhishek Sir dono teacher aur dukaan daar ban sakthe hai😂😂Sach!
I am very exicited for the session !!
Balle Balle Sir ji!!
Abhishek sir op acting lgta hain bollywood me aag lgane wale Hain💥💥
Yup sir we want another physics video like this 😊
Amajjing!!!!!!!!!!!! Idk how i was able to understand this being in 8th grade
Does light has mass?? I think it has no mass..
But to know the exact reason , eagerly waiting for this video sir. Ye ek informative video hoga , i hope
Will be an OP Video for sure 🤩🤩
sir but agar app light ko as a paticle consider karo jo displacment kar raha hai to e=mc^2 kee hisab se koi bhi object jiske pass mass hai (photon) to usko light ki speed se travel nahi karna chaiye right?
Marvelous!!!!
Thank you sir for this information.
Peace
What's a fantastic 🤘😝🤘topic that no one can thin ever of such a topic that do lights also weigh 🤔🤔
An extraordinary topic 💕💕
