51:41 instead of asking like or subscribe He said padhai achhe se kijiega or kuch bhi nhi. What a personality 🥰

I'm from Bhutan and I could get admission in engineering college after 12th grade by watching your videos. Now I'm in my dream college yet I'm still borrowing your knowledge,sir. Thank you for everything, Alak sir.

(For the last question) For time : u = -20 m/s; a = 0 m/s²; s = -40 m. Therefore, s = ut + (1/2)at² -40 = (-20)t + (1/2)(0)t² -40 = -20t t = 40/20 = 2 s For position : 1) With respect to particle B u = 24 m/s; a = -g = -10 m/s²; t = 2s. Therefore, s = ut + (1/2)at² s = (24)(2) + (1/2)(-10)(2)² s = 48 - 5×4 = 48 - 20 s = 28m 2) With respect to particle A u = 4m/s; a = -10m/s²; t = 2s. Therefore, s = ut + (1/2)at² s = (4)(2) + (1/2)(-10)(2)² s = 8 - 5×4 = 8 - 20 s = -12m

It's 2023 till students are watching this evergreen teaching of legend wow just amazing❤❤❤

"Main thaira raha, zameen chalne lagi" ~ Relative Motion in a Nutshell.

They will meet in 2s , and position from ground where they meet is 28m and -12 from top

time of meet = 2s position from A = 28m postion form B = -12m

Answer for the question in the end... They will meet in t= 2seconds and at A = 28m and B = -12m (-ve since displacement is downwards from initial position.) Thank you so much Alakh Sir for explaining all the concepts amazingly and helping all of us JEE & NEET aspirants!

The only youtuber who never asks to subscribe or like his channel. If agreed like😝

Me: My reaction when I see ncert problem - 🤯🤯🤯 Physics wallah: ye to halwa hai halwa 😂😂

The last thing u said "agar vdo pasand aya ho to padhai acche se kijiyega OR KUCH bhi mat kariyega" that hit me hard. Sir you're really brilliant teacher. To be very honest I would never ever loose hope and show neglection to my studies becoz if the teacher is so honest and sincere then why can't students.ill be studying really hard . Hats off to you🙏

17:23 , in place of -14 there will come -13..🙂

Other teachers: I guess you didn't understand. Physic Walla: Feel Nahi Aaya 😂😂

Ultra legend watching this to complete there backlog

-12 m from top and at 28 m The time is 2 seconds they meet after 2 seconds.

lakho rupiya de diye, offline classes join bhi karliye, end mein to yaha pe hi aa pahuche 😂

Akash and Allen : Concepts get clear Physics Wallah : Concepts get crystal clear 🤗🤗💥💥

Most relevant lecture required for this topic....17:23 mein 13 aayega sir...waise toh aapko correct karna mere jaise student ke liye is no less than a sin as it's just a calculation error and you are such great teacher

it's now 2022 but The old lecture of alakh sir is still diamond ( precious) for us..! ,🙏🙏🔥

41:05 In this question UBG = 20ms ABG = -1 ms² SBG = 150 m S=ut + ½at² 150 = 20t + ½ -t² Multipky both sides by 2 300 = 40t - t² t² - 40t +300=0 t² -30t -10t + 300 = 0 t(t-30) -10(t-30 ) = 0 (t-30) (t-10) = 0 t=30 t=10 Put both values in the formula the distance will be same so boy catches girl at 10 and 30 seconds

Nobody has explained the RELATIVE concept with this excellence to me. Dhanyawaad shrimaan ji💗✍🏻🙏🏻

I think it should be -13m/s At 17:46.

😀

Who is watching in august 2024

Time does not depend on frame of reference is not always true.Only true according to Newton but according to Einstein's Special theory of relativity, time is not absolute.

Gazab! Teaching Skill with most convenient example!👌👌👌👌👌

17:25 Vap= -13m/s

30:12 he somehow always knows , when we dont get it . people in my school keep proceeding even after we say we've got doubts .they be like ' practice karo ho Jayega ' . ❤❤❤

This man is a perfect example for changing the mindset of people about UP and Allahabad waale

Answer of last question T=2 & position of meeting For A (ball of top) = -12m and For B (ground ball) = 28m

छोरो न्यूटन और आइंस्टाइन की बातें वे विदेशी थे लेकिन physics वाला चेनल और हमारे सर भारतीय है गर्व से कहो हम भारतीय है

Who are watching in 2024 july

17:32 Dear students there is a error it should be -13 as 7-20 is -13 plz correct it

when teachers were teaching in institute and not understanding the concept. others -- "yar ab kya hoga " Me -- smiling and thinking , ab alakh sir se samjhunga and kal sabke samne hushyari marunga... 😜😜😜😂😂🤣

51:27 time=2sec and distance=28m or -12m(Downward direction)

Who are watching in 2024 June ❤

Best faculty in physics If u agree hit like

Time of meeting- 2 seconds Distance- 28 metres from point of B and -12 metres from point of A

Police : why I want to chase him?.. I have a gun. Thief : pls sir.. Don't use gun.. We use relative velocity. Police : 😓

They will meet at t=2secs When the ball at the greater height is coming down and has covered 12m, and the lower ball going up has covered 28m

Watching this video in the time of Coronavirus. Hope everything will get normal soon🙏

From A : -12m From B : 28m and after 2 seconds.

Answer to homework question:- They will meet after 2 seconds From ground at a distance of 28m and from top at distance 12 m downwards (-12m)

Time of meeting 2s Dist 28m. B From A. -12

13:11 " Tum log humesha mera naam puchte rehte ho My name is ALAKH PANDEY " aaj sabko inka naam pta hai....sir ko btane k zaroorat nhi...... This is called GROWTH 🥺💗✨

A best teacher...in the world Who can qualifiy JEE, NEET, and alll type of exams.. Such a great teacher...

17:23 ans -13m/s ☺️☺️

i am in 3rd year of college now,watching it again and feeling nostalgic. So happy to see what alakh sir has achieved now. Epitome of dedication, perseverence and hard work.Proud to be a PWian ❣❣

Teachers: Let's Derive How This Was So!!! Alakh Sir : Chalo baccho Tumhe Feel Dete h!!😁😁

Sir u should publish ur own written physics book❤️...that will be too much helpful for us and future aspirants ✌🏻💫

Its 2024 still watching his videos which never gets old ❤❤

17:30 there Should be -13

Ans of last question is: U(ab)-u(a)-u(b):20 a(acceleration) :0 S:40 T:s/u:40/20 T:2sec Position : A:25m/s S:24(2)+0.5(-10)(2 square) 48-20:+28m B:4m/s S:4(2)+0.5(-10)(2square) 8-20 -12m

Alakh sir's way of teaching is very superb . Alakh sir is a legend of physics.

Finally understood sir thank you so much ❤

Ans. of homework question.👈🏻 (1) time = 2 seconds (2) acceleration = 0 (3) relative velocity = - 20 m/s (4) position where both meet is 28 metres with respect to lower end and 12 metre from upper ends....👍🏻👍🏼

ans of last question is 28 meter above the ground and -12 meter down from the top🤗🤗🤗🤗

everybody: he expained the concept in a very easy manner me: by mistake he wrote 20-7=14 like i do in the spelling of explained

51:31 t = 2s & they will meet at 12m from the top of the tower or 28m from the ground.

Sir you are super 30 of RU-vid 😉

शाबाश, बेटे ! ईश्वर तुम्हें स्वस्थ, प्रसन्न व आबाद रखें। आदर्श कार्य कर रहे हो। अपनी इस यात्रा को पवित्र बनाए रखना, क्योंकि तुम अवश्य ही एक मील का पत्थर स्थापित करने की ओर अग्रसर हो ! God bless u!

Time 2s Position wrt to A -12 Position wrt to B 28

I feared relative velocity but this man is a magician he made me enjoy physics

Kids watch pradeep kstrapal Adults watch Walter lewin And legends watch physics wallah

At 18:00 [7-20=-13m/s] is the answer .. 🙂

unacademy : Don't tell anyone ,we also watch physics wallah for teaching others 😂 😂 😂

Sir a trolley moving front side with a speed 10 M per second, A man moving backward to 3 M per second, P person who is in the car moving forward 20 m per second (Answer = -13 meter per second)

Time =2sec Postion = 28m , -12m. Thank you sir for this lovely explaination❤️

The number of haters shows how many evil minded filty people are there in our society, how can you dislike someone who is not enjoying a luxurious life which he can get it in seconds and is working hard day and night for the underprivilaged students of the society, even bharath ratna award is small in front of the selfless work sir is doing.

hi bro.....thanks ...... ANS: time ::::2secs distance:::28meters above ground and 12 meters below the wall

It's end of 2023 but your lectures are evergreen..❤

I'm in 11th right now. Everything is new to me. Since 2 weeks I've been struggling with this topic. I always wanted to have a clear cut understanding of the topic. Finally I understood it completely and all thanks to you sir. You are that kind of teacher who everyone desires. Thank you sir, i don't have words to explain how your video helped me.

51:00 Time =2s The point where they meet is From body (speed 24m/s)=28m above From body (speed +4m/s)=-12m (means downwards)and if we sum the total length it will equal the relative distance b/w them

The displacement of ball from tower is - 12m And , Displacement of ball from ground is 28 m

Homework qs ....solution ....time A ND B MEETS= 2 SEC position they meet...accrding to A IT MEETS B whn it goes down to 12m Accrding to body B .WHN IT GOES UP TO 28m. It meets. Body A. Hence overal total dist given is 40m tht is 12m + 28m..= 40m Thank you alakh sir ...old never goes old... forever blessed❤❤

Only this teacher does not focus on teaching all the concepts but gives a feel in the concepts and relates in real life. bhaiya, yeh Alakh Pandey sir hai. Shiksha ki Alakh jagah hai, thay aur rahenge.

50:45 Ans : Time taken to meet is 2s and they will meet 28m from ground . 51:40 Agar apko ye vedio psnd aye to padai kariye aur kuch nhi ..😂❤️‍🔥

2015:- best book and teacher hc verma 2020:(sir)- hold my beer

at 5:48 ans will be -13m/s btw thankyou alakh sir u are best

sir,velocity of A with respect to p (car)observer is -13 m/s.

Sir i am an aakashian ... I didn't understood this concept there but what u taught is the very best..👍👍👏👏✌️✌️

really how he teaches........CHALO BACCHO TUMHE FEEL DILATE H..... the concepts he thinks are hard he repeat almost ten time we students are so proud that we have a teacher like you.............................. thank you so much sir O SIRJI TUSSI GREST HO.............

I had always heard the name of PW but when i entered 11th in april i realised that pw and alakh sir are not just a yt channel but an emotion for iit jee and neet aspirants Thank you sir ❤

they'll meet after 2s. at distance of 12m from top of tower or 28 m from bottom

17:23 -14 nahi -13 hoga.. Silly mistake 😅😅

If physics wallah taught ips preparation he'd be police wallah🤔

I AM SEEING THIS EVERGREEN TEACHING VIDEO ON AUGUST 😊

1st viewer! Ak love dedo!

17:34, Subtraction me mistake ho gya h( 7-20=-13) but concept clear ho gya

Ans of h/w quest is... t=2sec & S from B at ground =28m, S from A on building=12m. Is it correct???

5yrs old video gives me that knowledge that I can't get it from new videos with smart board ... Kuch to baat hai iss purane video me yuhi nhi ham bachhe fida huye alakh sir pe 😅

TIME 2 SEC POSITION 28M AND -12 M THANK YOU GURUJI!

Sir please upload the remaining concept of kinematics like parachute problem , rocket one and two balls at what time reach each other

When: 2secs, where -12m (from A), 28m (from B).

This lectures are still god gifted for us ❤❤ Like if are watching in 2024-2025

Our school teacher should go to Allahabad so that Alakh pandey sir should give them free tutions 😂😂😂

this teacher is so adorable! Like the expressions and affects he give in between the lecture. For eg that train sound chuk chuk chuk chuk 😂😂. Too adorable!❤

Time: - 2sec Position: - 28m above the ground!

Its 2024 still One of the best explanation of motion in 1-D
