This actually blew my mind of how question based learning we do jnstead of just grasping the concepts to its real depth ...THANKS A LOT SIR these type of blunders really needed to be corrected hope u keep bringing such eye openers ❤
Yes sir...i was also in that 93% who didnt considered air friction .... Thank u sir for clearing this concept of air friction and would always consider situation given in question rather than based facts 👍
Air friction in general isn't even considered while solving similar problems. It's pertinent to ask when to apply if the air friction is imparted upon the object
There is another way of comparing T ascent vs T descent in such questions: In linear cases of constant acceleration starting or ending at zero speed, we can say that distance=ut/2 or vt/2 u is the initial vertical speed imparted v is the speed of striking the ground and since friction is at work, vt T descent > T ascent
I think we need to talk to our coaching centres about how they only teach us 'IDEAL SITUATIONS' which eventually becomes our habit to take every case as ideal situation... i honestly thought that the upward motion would be affected but i got the opposite relations
Sir its a humble request to please explain every brain teaser concept in this way .. please Sir its very helpful 🙏🙏🙏🙏 . Please Sir atleast 5-10 minutes a day ❤
Yes sir, I also at first attempt thought the case will be just like a normal projectile and forget to apply air friction. Thanks sir for your guidance, from now I would try to look at the question more clearly and deeply
commenting at 2:36 , as i have read that projectile is only affected by gravitational force and thrust is not considered . i dont think that flow of wind horizontally wont affect the motion of projectile
I didn't even consider air friction i couldn't think of it in the first place but now i will certainly consider each and every point in questions from now on.
Truly eye opener for me. I really thought there is nothing more to do in this problem other than simple projectile formula. ❤need to practice more such qs
Exactly manai first method sai hi socha tha Infact earlier i came across a similar ques where neglecting air friction was necessary and was wondering why was this sentence mentioned THANK U SIR FOE THIS WONDERFUL QUES❤❤
@@gatecse6032 hmmm, so you are saying that just as the ball is thrown vertically it will gain the same speed in x asix as of air instantly........ noice good concept 😂😂
Wow,this is really amazing Thank you Ashish sir for your innovative efforts,Ashish sir is going to revolutionized the era's by his creativity,efforts,and love for physics and physics lovers
@physics galaxy, sir im in 11th and this question is eye opner for me because i always neglect air friction and sir iam very grateful that you providing this type of material and your books for student and sir iam frequently following it.
Yes actually it never occurred to me like this we are so used to neglecting air friction in the questions until specially written not to that in this case when the actual wind was flowing it did not even clicked me
Horizontal component of friction aapne consider nahi kiya... jisse Horizontal velocity constant nahi ho sakti .. eske liye hame ek naya external force assume karna hoga...vo variable (equal and opposite to the friction) sothat har instant pe friction ko balance kare... tabhi Horizontal velocity bhi constant ho payegi... sir❤
Horizontal component consider karne ki jaroorat nahin hai because question has specified that horizontally wind is imparting a constant velocity v1 so it includes everything in horizontal direction. You don’t need to worry about anything else present or not. Sir has said that be careful about the language of question which you missed it here…😊
Thats why i also saying that in question we have given constant velocity in horizontal direction that means that friction , buoyant force or any other external source is acting such that the horizontal velocity is constant it means that we just have to apply only horizontal speed to that particle and not to think about the forces since it includes all forces .... yadi aap friction es taraf se consider karenge to friction ka horizontal component horizontal speed ko constantnahi rahne dega esliye hame ek new force assume karna hoga... jo eski horizontal speed ko maintain karen ... @physicsgalaxyworld
Yes sir I was also thinking the same reason that vertical component of projectile will remain unaffected due to wind, only the horizontal component will be affected and neglecting that if there is then there will be a component of air friction into account in vertical component of motion thank you correcting me sir...🙏♾️🛐
Sir i have a doubt, In this question there will be horizontal opposive acceleration then the path will still remains parabolic or not sir please clear my doubt , thank you sir for this fantastic explanation.
Yes sir . I also had this misconceptions that horizontal component shall remain same for both cases , thus time of ascent and descent shall remain same .
Thank you sir i am a jee 25 aspirant and just tomorrow i started projectile motion and this question made me again think to make my fundamentals strong thanks alot 🙏🙏
yes sir maine bhi ye consider nahi kiya tha, from all these experiece i can say that reading and understading the question is most important thing to solve it
Umm my opinion on this is that yess it will be 2u/g only Because we have maximized descend time so basically it means we have minimized descend time So the resultant answer will be 2u/g
sir agar hum air friction ko le rhe the toh jab wind nhi chal rhi thi tab bhi consider karna chahiye tha jab wind nhi chal rhi thi toh time of flight sidha 2u/g nhi ho sakta waha air resistance nhi use kara toh mujhe laga ki use neglect karna hai
One doubt if upar jaate wakt ffiction hai so a >g but niche aate wakt bhi toh friction oppose karega then time of ascent = time of descent hona chshiye na ?
When the projectile is going upward the net acceleration will be summation of gravity and retardation produced by gravity .But while it is coming down the force of gravity and viscous force is in opposite direction , so net accleration will be less compare to first case. Hence time of flight in first case will be less as compare to later part
Its range will get increase ...... Bcoz of acceleration. But however time of accent and descent should have similar relation as of wind with constant velocity. ( According to me ))
First I made a blunder by thinking it incorrectly ,then I reader the explanation on telegram given by physics galaxy which I didint understand a lot bcoz I never new about air friction in problems so yes my thinking got evolved I feel that to exponentiallly thanks a lot sir..and i undersatnd it now completely

Sir, what will be the net effect of air friction on time of flight?
Sir , I am in class 11th and Love your lectures ... I wanna ask what should I do to increase my level of physics to Olympiad level
sir i have a doubt
i think air friction will act in opposite direction to relative velocity of ball wrt air
please corrrct me if i am wrong ???
sir 11th walo ko toh abhi air friction ka concept nahi bataya gaya
Sir can you explain if a accent>g then why velocity becomes zero at hmax
This actually blew my mind of how question based learning we do jnstead of just grasping the concepts to its real depth ...THANKS A LOT SIR these type of blunders really needed to be corrected hope u keep bringing such eye openers ❤

Air friction in general isn't even considered while solving similar problems. It's pertinent to ask when to apply if the air friction is imparted upon the object
Yes this habit is making us to exclude external situation which we must avoid ... especially for advanced
Me too
Sir AP please hme regular pdane lg jao kisi online batch mai
Yes sir
no need sir 😊
Sir teaches in offline... isn't it more than enough that a star batch teacher is teaching for free online
@@DeepanjanBaralJEEhume bhi star batch ke teacher padhate hai
25 cr per annum lene wala online kaha se padhaega
I come in that 93% who thought Ta=Td but I will consider air friction
Thank you sir
Be honest u didn't 😂
@@ProPeeps bro he said he was in 93 percent
There is another way of comparing T ascent vs T descent in such questions:
In linear cases of constant acceleration starting or ending at zero speed, we can say that distance=ut/2 or vt/2
u is the initial vertical speed imparted
v is the speed of striking the ground
and since friction is at work, vt
T descent > T ascent
Sir please keep uploading this type of educational content always.
I think we need to talk to our coaching centres about how they only teach us 'IDEAL SITUATIONS' which eventually becomes our habit to take every case as ideal situation... i honestly thought that the upward motion would be affected but i got the opposite relations
This is simple. Its because air friction is negligible we are ignoring it.
6:37 just loved the way he explained ❤❤

I pass my time watching physics in minutes from ashish sir and phd series from eduniti😂
Bhai tum shorts dekhne ke liye time pate bhi ho?
Yes sir,I also forget to apply air friction.
Abse dyan denge sir ❤
I didn't even consider air friction i couldn't think of it in the first place but now i will certainly consider each and every point in questions from now on.
Hi sir I follow your electrostatic book and it is very helpful
Truly eye opener for me. I really thought there is nothing more to do in this problem other than simple projectile formula. ❤need to practice more such qs
Yes sir I was unable to think about it but now I will surely think more about such types of questions
Yes sir I wan unable to think it but from today I will think in multiple dimension😊
Yes sir mai nhi soch paya tha phle but ab clear ho gya.
Thanks a lot sir ❤
sir this was so amazing! pls bring more questions for 2025. its a humble request. questions like these surely will teach to think in a broader manner!

Infact earlier i came across a similar ques where neglecting air friction was necessary and was wondering why was this sentence mentioned
THANK U SIR FOE THIS WONDERFUL QUES❤❤
Data(93% people won't able to solve it) aisa bolo ki 4 log video par click karein
Air friction nahi socha sir usually in every question ....
Now understood
Your content is far ahead of time sir..Hats off
Actually the range will also change since the ball will accelerate in horizontal tiil it reaches the speed equal to the speed of air ❤
Why will the ball accelerate . It will just move with velocity of air horizontally from starting
@@gatecse6032 hmmm, so you are saying that just as the ball is thrown vertically it will gain the same speed in x asix as of air instantly........ noice good concept 😂😂

Mene ye socha hi nhi tha. Thank you sir
Sir maine Air friction ke baare me nahi socha tha lekin ab samjh gya.
thank you sir learned new concept
as soon as i read this que , first thing that came to my mind was effect of air friction on g
Yes sir honestly ye mis hua tha ❤
Ji sir.... In choti choti cheezo pe aur dhyan dena padega... Thank you for the wonderful explanation 🙏
Yes... Sir.. Mere ko initially yahi laga tha.. Par ab samjh me a gay
5:10 @physicsgalaxyworld But sir what can we say about the total time of flight? Will it increase or decrease?
Yes Sir, this was an eye opener question.
Yes sir, I also did not think of the air friction aspect. Thank you sir for giving the clear cut concept.
Sir e concept pata nehi tha .. thnks sir batane keliye
the real god of physics :)
Yes Sir, I made the same mistake before your explanation.
Sir I was one of those who marked the answer when saw time of ascent=time of descent. Thank you for the explanation.

Yes sir, great small concept ❤
Sir i have not thought this way
You absolutely great sir 👏 👍
Unable to think in beginning..but now I will pay more attention to this part
Sir friction ke baare me pehli baare me click nhi hua tha. But it helped right now. Plz upload more videos like this.
Yes sir , me bhi nahi soch paya air friction ke bare me
Question start at 1:50
Can be done geff for 2 case ... Case 1 ascend, case 2 descent

Sir i have a doubt, In this question there will be horizontal opposive acceleration then the path will still remains parabolic or not sir please clear my doubt , thank you sir for this fantastic explanation.
No it won't be parabolic because the acceleration is not constant
honestly couldnt thought of air friction , thank you sir
Sir main nhi soch paya😢
nhi soch paya tha sir but now i understood it thanks
Yes sir . I also had this misconceptions that horizontal component shall remain same for both cases , thus time of ascent and descent shall remain same .

yes sir maine bhi ye consider nahi kiya tha, from all these experiece i can say that reading and understading the question is most important thing to solve it
I also didn't think of considering air friction. Thank you sir
Btw Ta + Td will be still 2u/g right?
Umm my opinion on this is that yess it will be 2u/g only
Because we have maximized descend time so basically it means we have minimized descend time
So the resultant answer will be 2u/g
thankU sir
Yes sir it was truly an eye opener
Thanks sir for i made the same mistake but these very fundamentally important thing helps so thank you
Yes sir initially we used to ignore these things
Yes sir nahi soch paya tha
Yes sir maine bhi Ta=Td socha tha....but jaha aapne air friction ka namm liya ...mujhe chamka or phir sahi concept k sath sahi ans aa gaya ❤
sir agar hum air friction ko le rhe the toh jab wind nhi chal rhi thi tab bhi consider karna chahiye tha jab wind nhi chal rhi thi toh time of flight sidha 2u/g nhi ho sakta

I will improve my thought process.
