Work, Energy and Power | Revision Checklist 06 for JEE Main & NEET
Vložit
- čas přidán 13. 12. 2019
- One of the most important topic of Physics for JEE Main and NEET is Work, Energy and Power. This checklist video of this topic is for fast revision of all the possible concepts on which questions are asked in JEE Main and NEET.
Important questions in work and energy topic are based on static calculation of work, kinetic energy, potential energy and graphical analysis. In most of questions combined applications of newton's laws and work energy theorem are also asked and in problems based on such situations free body diagram as well as equation of work energy theorem both concepts are to be applied. Concepts of friction and NLM are very useful in solving questions based on work energy theorem. Questions based on power are asked in two categories - one is for calculation of average power and other on instantaneous power.
Concept of equilibrium related to potential energy of force field is also very useful in understanding this chapter as in many books students miss out the details of stable equilibrium, unstable equilibrium and neutral equilibrium. Relation of force as gradient of potential energy is used in determining the state of equilibrium using the potential energy graphs. Watch this checklist video to build your concept strength of this chapter to next level.
Ashish Arora sir is covering all types of questions expected for jee main and neet for the topic of work energy and power just about 45 minutes.

thanks @sense_storiess, this saved about 30 minutes for me
Sir physics checklist is awesome
Plz make this for chemistry also by any chemistry faculty.
No proper revision videos are available 4 chemistry on CZcams like physics
How many of you r agree with me
eSaral is best for both chemistry and physics revision
@@tusharkesavan8652 catalysis toh tatti hai...esaral is also ok but not great.I think you never prepared for jee advanced or have seen the questions....otherwise you would know.
Catalysis be vedantu is the best!!
Yes sir....ur revision checklist videos are the best in the whole world....Thank u for making this......🙏🙏🙏😍😍😍😍
Which is the best channel for chemistry revision guys? I'm lagging in chemistry, suggest me a channel please!
Fun fact: 90% of viewers haven't made their checklist from PYQs and are completely dependent on PG revision checklist😅
and you are one of them🤣🤣
@@shivamjain3450 That's why I commented
Same here
yes🤣😅
I'm among the left 10% 😅
Actually, I revised all topics from eSaral, but WPE, COM were not present there.
No Unnecessary Talk Only Straight To point And perfect explaining, Superb Teaching!!
unlike unakadmy channels
@@harshvardhan7600 unlike physics Wallah.
@@makundaram8035 I think both Alakh sir and Ashish sir are doing great job 🙂
@@makundaram8035 Yes physics wallah also sometimes sing sings jn between the lectures which irritates me a lot
@@sumitnaiyaa sarcasm nahi samjhoge tum dost ..
hello! I am FUTURE ,ashish arora sir congrats for winning noble prize in physics
Ah yes, a structural biologist being awarded a PhD in "Physics" for creating educational content. Yep. Seems legit.
@gameaddict Guy I am from future and u will change your CZcams channel name to gameaddict Gay after few years
9:30 , we can do it simply avoiding dot product.
Work done = Force * displacement in direction of force
horizontal displacement by taking component of string length is Lsin(theta), and work done is positive because direction of force and displacement are same
Hence work done is Flsin(theta)
Thank you so much 🤝
Sir I extremely thankful to you for these revision checklist.
I'm felling so much confidence after making the checklist.
Thank you so much.
That fulfils our target then. Subscribe to our channel to stay tuned for more.
Thanks
@@physicsgalaxyworld sir from where we can buy the previous 18 yrsjee main question containing book ?
@@architdeb1113 From Amazon.com
Good part of all these videos is that Pogi knows what to clear what to not😂
Why are you gai
Pogii kinda cute though
Bhai is this only for mains or advanced too??
@@narutosenpai2250 mains only
@@narutosenpai2250 I could solve many Advanced questions as these checklists clear the concepts from the root. But these are mainly for JEE Main and NEET
Honestly , deep revision experience !👩🎓
A bonus advantage coming at this channel is that there are no advertisements to hit my focus , to disturb my learning hours when Ashish sir teaches. 🙏

Pogii board clr krne k sath sath..next heading v likhdeta hai...amazing 😂😂🤩🤩
Pojee😂
Pogii nhi Og bolte hai sir
Extremely thankful to teachers like you who are so much dedicated to teach the subject with the best easier, simpler and obviously perfect way...god bless you always
@@pranjalsethi938 ya why not
The only teacher who says, itne se ho jayega jee ke sare Qns. And the level of confidence associated with it is unspeakable.
These checklist videos are so helpful! Thank you so much sir. I've recommended these videos to all my friends and they've found these useful too.
FAR BETTER THAN ANY ONE SHOT ON YT.
Sir, you are increasing competition by teaching this. Superb explanation. Thank You
I learned more through this 50 min checklist than I learned in 2 years about this chapter... this chapter is very conceptual (imo) but coachings mainly focus on its mathematical part and problems
thank you sir!
Couldn't thank you enough. I am in 11 and I have started watching the checklist videos for my 11th revision as well. The content is super. Thank you so much sir. You are indeed shaping the future of thousands of aspiring students. God bless you sir always
Thanks for your appreciation words for Ashish Sir...
Thank you so much sir... Revising from checklist videos within an hour boosts my confidence..
Thank you for your good words. Subscribe to our channel to stay tuned.
this rivison video is better than Jee Wallah one shorts and long leacture 😂
Hm..aap to baas dusro ko naam hi rakhte raho 😝😁
@@Deactivated_account2025 tuna kya kiya ha jee Wallah main padh ka
Such a great impactive effort thank you so much sir for this revision. You always provide that material to us which we want at correct time.
Dear Harshita, really thankful for your appreciation.
Hii
Sir made physics revision a piece of cake. Revised everything, this the best series. #PhysicsGalaxyIsTheBest
Hats off. You're doing a great job. God bless you
Sir, I m in love with posi (PG)😊😊.A very good whiteboard monitor.😉
Haha, he loves to help!
pw and pg are life savers
Very nice and smart presentation. Namashkar.
9:48 L1 is not in the direction of force so work done is not F * L1 but F * L sin(theta).......
here it shld be like that , 2Flsin(theta/2)cos(alpha) , where alpha is the angle betweeen l1 and f
0:15 watching this checklist is better or watching the PYQ revision series of Work power energy?
Both
This checklist helped me revise all the concepts quickly. Thankyou sir and thanks to your whole team.
These videos are just cherry on cake!!!!! made my notes from these checklists and they are helping a lotttt👍
Seedhi baat , no bakwaas !! 👏👏👏🙌 🙌 👌
2l sin(theta/2) Kasse aya 10:00
kaise??
Sir please upload checklist of all Class 12 chapters also especially Ray optics sir please
Sir is insanely awesome sir will definetly make it before jee mains January bro so don't worry he is awesome I mean I have never seen a teacher so organised and so well maintained he has made everything in points wow rather than teaching them without heading or teaching in one slide he has made points in different slides of board and he uses pojy as a board cleaner 😂😂😂😂😂 one of the most joyful teacher who teaches seriously with some marvellous kid technique like pojy so that the session does not become monotonous just wow and wow
@@asishbauri7433 Definitely bro Sir is the best mentor but it's just a request of mine Cause sir make you revise and recall all the concepts Instantly and in a very short period of time your chapter is prepared for mains level
@@aryankr427 sure bro u r correct
Dear Aryan, sir is squeezing out time from his busy schedule and recording videos in a systematic manner.
@@physicsgalaxyworldplease sir, required pyqs of jee advanced
Sir I am being Selfish but Can we please get twice video a day One for grade 11 and one for grade 12 please sir🙏🙏🙏🙏
It's not about being Selfish sir knows our emotions well bro
Ye Idea sahi hai daily one video for grade 11 and one for grade 12
Dear Kumar, sir is trying his best to take out as much time as possible.
@@physicsgalaxyworld sir, where is today's video
@@physicsgalaxyworld Sir plzz upload today's video . Sorry sir but upload it everyday , we need your help sir .
This is best channel for physics rather then wasting time in physics wallah 😊
Physics wallah is good for basics physics galaxy is good for advanced
A gem fr class 11 students also ......thnk u sir😇😄
After watching concept videos
Fundamentals on its peak 🔥💫💫
I am really impressed by this idea of checklist videos. I am really thankful to sir for this initiative. Even the content quality is top class. #PhysicsGalaxy

Amazing revisions videos very very helpful ❤️
Thank u so much for boosting our confidence I am extremely thank you for your support and encouragement
Sir please to provide guided checklist of all the chapters of Physics. it would be very helpful because we are having less time to prepare it, as we are giving tests also
Sir make a playlist of this checklist then I can save that playlist in watch later pls sir and I can watch in a jiffy in a sequence pls sir
@@saurabhsharma3125 at 9:30 how did sir got l1=2l sin ¢/2
Please help brother
@@karanvirsingh2830 draw a perpendicular from point of hanging it devide theta into two part ,and then take componant
@@PrakashKumar-mb6de can u elaborate
Draw 📐 with sides l , l and l1
We see that this is isosceles
Drop perpendicular
Use trigonometry
Top notch content sir🔥🔥🔥
INTRO seems like it's going to be a meditation session..😌
Variable force 10:10
Can anyone tell me how L1 = 2sintheta/2??
bring down the perpendicular. now we have 2 right angled congruent triangles with one of the sides being theta/2. see the image and you will understand what I am trying to say. Hope this helps!!
Sir , please make video on rotational mechanics concept .
Dear Badhil, you can watch PG concept videos from our channel/website/mobile app
Sometimes I am scared to share because my competitors will get to know about this checklist then they will easily beat me 😰😰
@Namit Sunilya 😂
1:44 video started 🇮🇳❤️
Sir these are very helpful I wish you cotinue this series
Sir please take Class 12th topics also sir very few days are left please sir 🙏🙏🙏
So what was your score does this video help you??😊
Awesome content 🙏🙏
Waiting for next checklist
Best teaching meets best concept
SIR U ARE DOING GREAT FOR US THANK YOU
Plz DO IT FOR ALL CHAPTERS
Sir at 4:05 am having too much confusion because everywhere it is written +ve => gain & -ve => loss (supply) of energy can u clarify further
It's 2024 and this video is like blessing for me thankyou so much sir ❤!your video helped a lot to revise complete physics for neet you must be honoured by national award 🙏🏻
true
Anyone can tell at 9:39 why l1=2lsintheta/2
Thank you sir
Excellent .. teaching...
Thank you sir for awesome video
But I think you missed out conservation of mechanical energy concept
Sir your on making checklist is really help a lot of students. Thank you sir for giving your precious time and teaching us how to solve questions with ease of understanding
Thank you for your good words. Subscribe to our channel to stay tuned.
My pleasure sir
Thank u sir.
.. Videos bhot helpful hai... Complete series banaeyega... Plzz thank u.
Sir I know I am being a bit selfish but please can you start a similar revision sort of course for Advanced as well with some good problems of JEE Advanced even if it takes a year or two it would be fine as I am a JEE 2022 aspirant xd...Btw thanks for ur efforts sir it was of great help...
U have commented in another video that U r a educator at unacademy and that U cleared iit jee and is currently pursuing cs at iit delhi. Then why r U asking for adv checklist
Also U say that U r a 2022 aspirant 😁😁
@@Realisation404 wtf 🤣
Sir, you have left the spring + chain concept...
Wow really great explanation...!
❣️
Why very much lesser number of advanced illustration of this chapter??🙄🙄
Pranam sir and thank you
Sir this physics checklist was very help full to me , thank you so much sir . Please make these type of checklist for every topic sir thank you
44:15 what does supply and gained mean?
You might have seen the same type of logic in thermodynamics
Best way to revise
Suprb lecture😊. Liked video before watching 😁
Sir you are a God for procrastinators like me!
Great work 👍
Very thankyou sir t u for this checklist .
Sir pls make strategy video for April jee mains and how to use these videos to get maximum benefit
It's really nice sir,the way you revise concepts upto the point.
Good sir 👍👍👍👍👍
What a super lecture
video baad m dekhta hoon ...phle like kr deta hu😊
17:28 how come sir have mentioned PE and non conservative force in one case
Sir, you work so hard. Thanks sir
thank you sir for these checklist videos...if only they were in english/had subtitles..........it would be more helpful
Leaving for future reference
9:00
Sir isn't 9:34 wrong we should take Lcos theta
no it is right
Sir in calculation of work how did we take out the L1 value and is the work done zero?
dont know y but..i just love the way sirs explains..nd wanted to know more abt phy nd poji also
Thank you so much sir... 🙌🥰
Thank you Sir very much
Sir if we supply(+ve) power to a body then energy will be gained(-ve) so how can I tell about sign...???
i had the same doubt. have you resolved it now?
Waiting for checklist of any class 12 chapter.
sir *47:30 * horizontal velocity is same but angle will differ right?
sir since many questions in neet are coming one liners , i request you to make a one liners q video
also
sir calculation of work mei block A ke liye l1=2lsin(x/2) kaise (x=thita)
Sir, which all chapters will be completed before jee mains
Automobile power = driving force× automobile velocity
