Center of Mass | Revision Checklist 09 for JEE Main & NEET Physics
ฝัง
- เผยแพร่เมื่อ 5 ต.ค. 2024
- There are many questions from the topic of Center of Mass which are asked frequently in both JEE Main and NEET previous year papers. This checklist video on center of mass is best for quick revision of all types of concepts on which questions are asked in JEE and NEET. This is one of most prospective topic on which questions are asked in paper.
All the concepts like center of mass of subtractive objects, additive objects and combination of objects are important and Ashish Arora sir has very well quickly covered all such concepts in this physics video lecture including the cases of velocity and acceleration of center of mass and also on displacement of center of mass.
With the understanding of center of mass velocity and acceleration it becomes easier to gain an edge over conservation of linear momentum which sir has explained in the last concept of the above checklist video beautifully that also forms the basis of next checklist on collisions and conservation of momentum.

Hello sir,
I really like ur video quality. I want to start my channel regarding some informative videos. Kindly tell me which camera do u use?? And what lights u use. I will b really thankful to you
mera aa rhaa he ,,,,R/14 ,,,in that case of sphere
@@djking4907 mera bhi
when you say poG to clean your board and then you say thank you to him even if we all know you clean that board ..........you are one of the very true personalities...i respect you very much. You are an ideal for me. Thank you very much for this checklist series. Hope you will complete it very soon.

I was worried why there is no update today but after seeing the notification I had a big smile on my face. Thanks sir
Same here bro.
Same here also bro
hi
Rohit, did you crack IIT?
Yes what was the result
SIR NEVER LEAVE THIS CHANNEL
😫😫😫😫
WE LOVE U SIR .......
Fact: 98% people only dependent on Ashish sir's guided revision checklist.........and not making their checklist from previous years
Rest 2 percent go to iits
You got the reason wht IIT selection ratio is 1%...

Sir that's answer at 12:53 com of subtractive object in case of sphere is R/14. Is that right?
Yes
Yes mera Bhi R/14 aaya hai.

Now i understand how allenitie achieve AIR-1.
Only due to gem💎 arora sir.
Bro allen ke pass arora sir se 100 times achche faculty hai
Note- I am in class 12th in TTPS(star) batch in allen kota
and my name is Devendra
And best teacher of physics in kota till now for IIT Jee is D.B. Singh sir
@@DevXedits really how are ur classes going
@@ArunKumar-oi1vgat their best
@@ArunKumar-oi1vg but allen wale HOD's ko nahi bhej rahe class lene ke liye wo log aise teachers ko bhejrahe hai jinko bilkul bhi experience nahi hai
Sir as i m observing that views are not increasing on these checklist videos....
You should use some more attractive keywords like jee sprint or crash course for jee2020 to increase audience...also using allen brand name for your videos will have a significant effect on views....
Yes right
Sir is brand in himself....and views doesn't matters
If Views will be more , Competition will increase. So let it be a secret.🤫🤫

Sir I love the way you simplify the concepts and present physics in a very beautiful way.
Please start class 12th checklist also.
We are being benefitted a lot from your

If we took 3D sphere then ...
Shifted COM = -R/14
(-ve represents direction of shifted COM along -î )
yes
Correct 💯
Sir, I don't really know how to thank you thank u so much sir
Study well! All the best!
I am lucky that all revision checklist has been uploaded already
Thanks sir
Sir in the concept of COM of subtractive bodies -
The COM in the situation where a SPHERE of radius R/2 is cut from a larger sphere of radius R, the answer ----> x=R/14.
This was the homework you had assigned.
Please confirm my answer
It is correct
yes
Although if you do not get too much support but plz never stop,usually great things do not come in recognition too fast.Immense love ..
what are even talking brotherr recognnition...duhhh ppl call it pasion
Itne ache se toh mko apne class k lectures m v smjh ni aaya tha 😂😂 tqq sire 😃😃❤
ha yar thumne sahi bola
ha yarr sahi bole aap☺☺❣️ ashish arora sir is best of all time❤❣️❣️
Sir please upload lecture on JEE(M) Error Analysis.....
Plzzz Sir
very soon
Sir, Page no. 160 HC. Verma (volume-1) question no. 5
Solution is given R/3
But by your method it is coming R/4 please check it sir (Com of subtractive bodies)
points 3 and 4 were amazing... these types of questions are not really tough but demanded time which can now be reduced substantially
POJI is still a MYSTERY(:
Bro it's not poji it's pg and it's character that comes when slide change
@@mabhisitylive3606 mujhe pata hai bro already 😅
Sir the answer in the 4th checklist point that you gave in homework is R/14.
Sir, the answer for the COM of subjective objects of 3D sphere is x=4R/7.
And,the answer for the COM of flat geometric objects of the letter 'T' is x=5a/2.
Thank you sir, my result will be a great salute for you.
Thanks sir you're transcendent &, great teacher .
Thanks for your good words. Subscribe to our channel to stay tuned.
nice vocabulary
After this we can clear neet as easily as PG clears the board 😃

I had never studied this chapter in whole of 2 years of 11 and 12 but for AMUEEE it is important and I have studied from you and I really got it..

Sir Ji aap ko sat sat pranam .aap ka padanr ks tareka.( Point to point ) is best . You made us understand it easily . Now feeling confidence . Phod ke aana hai paper
Pure and raw teaching 😍
God of physics 🙏🙏🙏🙏🙏u r my inspiration..thank u for being our physics family
R/14 is the shift in a sphere of radius r with -ve mass of radius r/2
Answer in the case of sphere is R/14....
Sir your intro always make emotional I have extreme love towards science and maths (its amazing to consider how beautifully we humans are trying to understand our origin)
aiming for jee 2024?
Sir this is first time i watched your checklist video, I will say its best. It gives a lot of confidence. Thank u
Sir, you are amazing, if someone just watches only your PYQ without even doing anything else he can easily beat up to 35 questions
Did you crack it
Com of remaining sphere will be kr/2 = 7kx
...solving we get,
x = r/14
Sir please upload previous year IIT-JEE advanced subjective and integer ques
Only 8 days left it will help us in that approach
Sir in love with ur lectures. I'm imagining if why I haven't got to lectures earlier. Nicee explanation sir, keen to see every lecture of ur playlist. Thank uh so much sir for such awesome teaching 🙏❤️

kaash pehle dekh liya hota toh feb and march mei ache ajate :(
Yaya 🔥 ofcourse
Lo boards postponed.. ab to time bhi mil gaya dude..! 😂

PLEASE REPLY TO ME!! 🙏🙏🙏🙏🙏
BTW thanks fr the video series!!
Very very very helpful. We are blessed to have you with us ...sir
What u doing now bro😊
SIR COM of subtractive objects is (R/14 )
x = R/7 opposite to where the sphere is removed from, if radius of the removed sphere is r and the other is 2r.
Kabse wait kar rae thi sir lecture ka
I will recommend this to all my friends....
Thanks You for this initiative Sir 🙏🏻🙏🏻
U are th best teacher of physics in world🤩🤩👌🤑🤑🤑🤑🤑😍😍
wow best place to revise for mains in negligible time!!!
25:22 Center of mass of cone and sphere is 4(3r^2+h^2) /16(2r+h) got sir....
I love you very much sir.
Sir your looks are as dashing as your knowledge delivery is. Knew your channel for a long time but didn't paid attention now i am regreting.
Short and precise
R/14 is right for solid sphere subtracted object.
Sir please make chemistry checklist also from chemistry specialist teachers
30 minutes me sare concepts are Cristal clear
Sir Have you Uploaded any Detailed Explained video on Normal Reactions on inner and Outer wheal in circular Turn.
1) If you hv uploaded, then plz give link.
2) If NOT then Plz make.
Please 🙏 🙏 🙏
x=R/14 for case of sphere
Xcom= Mx-mx'/M-m can also be used but ashish sir's method is better 👍
Best teacher ever I have seen ❤️❤️
Thank you sir for butifful explain of concepts.
The c. O. M of left over spherical shell will lie at a distance of R/14 m from the centre of sphere
Awesome explanation of com in just 34 min all concepts are included in this checklist thank you sir ❤❤❤❤❤❤❤❤❤❤❤❤
21:55
COM shifted by distance R/14
Best for revision.
sir i am grateful to you as i have never got a teacher like you.
Sir a big request.pls make some strategy video for those also who r about to end their class 11 and start with class 12.if u r very busy right now,just make a video on books for maths and chemistry.thnx
Shifted R/14 towards left in case of sphere
Amazing revision material your are giving sir..👍🏻🙌🏻🙏🏻
13:04 R/14?
you are hope of rise for students like me
