In question three... Loss in kinetic energy is to be found.... But we know that in elastic collision... Energy is not lost.....someone please clear my doubt
Sir in question 8th 1:02:30, ham wall ko rest pe nhi la sakte by relative velocity zero karke then m2 ki velocity ulta karke m1 me add then m1 velocity=3m/s vo same velocity se rebound ho jayegi?❓❓❓❓❓❔❔❔❔❔⁉⁉⁉⁉⁉⁉
44:10 par dekho waha minimum velocity nhi use kar sakte kyuki vertical circle complete karna hai aisa kuch nhi kaha hai Waha simply work energy theorem use kar rahe honge hum ✓3gR jab derive karte hai toh bottom par ✓5gR lete hai waha se nikalte hai

Easiest way to do this question 😀😀😀
Since Wall 🚪 is heavy, so its velocity will not change after 💥 collision.
🌍🌏🌎🌍🌏🌎
Hence we can use....
u1-u2 = v2-v1
2-(-2)=-1- v1
=> v1 = -4m/s

sir in Q3 if collision in elastic then there should be no loss in energy right?
Faltu ka doubt mat create kiya karo😢
Bro system ki energy rehti hai same
Wo ek ball ka bola hai
Sir aapka padana ka tarika bahut acha hai
Padhte padhte pata hi nahi chala kab lecture complete ho gaya 👍🏻👍🏻👍🏻
Thank you so much sir
For providing us best quality education 👍🏻
39:00 correction
c) 0.5m/s and -0.3m/s
Sir,que.no.5 was tricky,you misread it,the answer should be (c) because it has been asked about Vb and Va respectively ❤️
Great lecture sir🔥❤️
Yes, I was searching for this comment
Correct
Can someone please tell sir ne kya sirf formulae ratwayay ya pehle ki tarah feel dilaya
@@hitlerbaba4008 ye feel pane ka samay nahi hai...we have our neet after a month...less time..hence, ye quick revision ka samay hai! If u wanna get that feeling then visit sir's old lectures of class 11 as sir said.🙂
@@sohinisaha2609 that might work for you sister but mujjse formulae yaad nhi hotay mujhse koi trick ho yaad krne ki to batado.
Sir Kuch bhi ho puri syllabus apko hi khatm karna hoga. Teacher change mat karo yar plssss 🙏. Bhot sahi jaa rha hai and you're the only umeed I have in my life now. Please change mat karna. Please sir
1:33:06 is the formulae of change in kinetic energy right????

Rebounding of Ball after collision with ground ke question aate hai kya NEET MAI?
Aapko tough laga pad le bahii padne meh kya jata hai. Keep gaining knowledge
Chapter complete hai kya bhai? Last mein achank khatm hogya shayad
1:25:26 I watched it many times 😂😂in 2x speed
The best part is he doesn't waste a single second here and there. He is so fantastic, I can sit and study from him for whole day🤩🤩❤️
In question three... Loss in kinetic energy is to be found.... But we know that in elastic collision... Energy is not lost.....someone please clear my doubt
In elastic collision energy don't loose in system,right. but in the question,asked energy lost by individual mass
@@chaitu1276 OK I got it..... Thanks
Congratulations for 5M Subscribers.😱🔥🔥🔥🔥🔥
ua-cam.com/video/7qTL9AYEIG4/v-deo.html.
All those who skip the ques for which Alakh sir says "abhi tak aisa sawaal pucha nhi gaya"....
There are lots of good qualified teachers in PW..
But Alakh Pandey sir was is and will remain the teacher who explains even the hardest topics easily
Sir question 5 mein c option aana chaiye
Kyoki waha par phele B fir A ki velocity poochi hai
Yes I also was in search of this only
Yaa. It should be c
Hn mai bhi yhi kehne aaya tha cmnt dikh gya
We reach 5M subscribers mark . congrats to all 🎉🎉

Sir in question 8th 1:02:30, ham wall ko rest pe nhi la sakte by relative velocity zero karke then m2 ki velocity ulta karke m1 me add then m1 velocity=3m/s vo same velocity se rebound ho jayegi?❓❓❓❓❓❔❔❔❔❔⁉⁉⁉⁉⁉⁉
who is here watching it for AITS and NEET 2023 ??
Naa broo for compartment
how can someone teach physics very nicely so good alakh sir thank you dam helpful video
Practice sheet nhi mil rhi kha milega didi
According to minimum velocity required to complete vertical circular motion v=√3gh
44:10 par dekho waha minimum velocity nhi use kar sakte kyuki vertical circle complete karna hai aisa kuch nhi kaha hai
Waha simply work energy theorem use kar rahe honge hum
✓3gR jab derive karte hai toh bottom par ✓5gR lete hai waha se nikalte hai
Thank you sir

Thanks for 3 likes😎😶
Ans for the last question is e^4h ❤❤😊😊
Alakh sir legendary man who touches million of Indian students hearts ❤️
Sir,
At 39:09 , In that ques, they asked Velocities of B and A so the option will be "C"
ua-cam.com/video/NCtBnaoXW1Y/v-deo.html
Yes
Sir bhi jald baazi kar gaye meri tarah😂
In question number 15,we can also use Kinetic energy conservation rule.
Congratulations Alakh sir and team for completing 5M subscribers!
You all have been unstoppable. Thank you sir for being an inspiration for us
"Buy now" dekhe heart attack nahi aana chahiye 😂😂😂😂😂😅

Sir in case of inelastic collision.. Momentum remains const bt kinetic energy not.. How.. I mean velocity to dono me common h😐
2024 attendance here
Alakh sir ke alava khi smjh nhi ata
This is known as consistency of teacher but what about Students who always plays blame game
39:27 The answer To This should be c ,since The velocity asked in The Q is B is to A right ??
39:21 shouldn't it be C as it ask b and a ?
S
Concept totally cleared sir ... thank u very much😊
39:06- option ‘c’ is correct not ‘d'
7:07 sir distract to aap huye hm to prh hi rhe h😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂

Alakh sir is love.❤️
∆k/ki = (4m1m2)/ (m1+m2)²....... Mentoz method for fraction of kinetic energy loss in collision... Time saving... Should apply... Thank you..
