- Lets solve some numericals on motion class 9. Here I've explained you "How to solve numericals on equation of motion class 9 numericals ." Here we are solving numericals of chapter 1 motion of class 9 science. Equation of motion is very important part of your class 9 physics.
I hope you will understand how to solve these kind of numericals in easy and simple way.

Honestly batau toh mujhe apse samjh atta hai compares to pw teachers ❤️
Sab chapters cover kijiye sir please 9th ke liye jld 👍🔥
Question 2 ka (ii)
2as=v2 -u2
=2×12×s(120)2-(0)2
=24×s=14400-0
S=14400/24
S=600m
9:01 yha par acceleration due to gravity 9.8ms^2 hota hai sab 10ms^2 kyu lete hai?
Acc due to gravity ki actual value
9.81m/s² hoti hai isko usually 9.8m/s² liya jaata hai... Lakin kabhi kabhi calculation asan rakhne ke liye isko
10m/s² bhi le lete hai
Sir aap jaldi se ye chapter par video banaiye, mere school ke treacher bahut hi ghatiya padhata hai, class me kisi ko samjh nahi aata bas pit-te rahta hai. Usse padhane bhi nahi aata, lekin Aap sir super ho bahut hi aache padhte ho. Aapka har baat samjh Aata hai.
Baat to sahi h same which schl?
7:37 v² = u² + 2as
(120)²=(0)² + 2×12×s
14400=O+ 24s
14400÷24=s
600meters= s is ANS using 3rd equation of motion.
Sir pls aur v numericals me achhe level ka question krwaa dijiye. ❤🙏🙏
v²-u² = 2as
120² - 0² = 2×12×s
14400 -0/24 =s
14400=24 = s
600=s
Therefore, distance travelled is equal to 600 m
Bhai please write all formulas physics
Mila to meko bhi dena
Sir I am class 9 now thank you so much sir for us teaching ❤❤😊
You're welcome 🤗❤️
Thank you bhaiya😇 bauhat achi video thi
Please sir aur question ke video baniye please bhaiya😇
Nice numericals but sir paper 12 ko tha
And I got just 50/100 😢😢😢
Bhaiya science ka sara chapter ki video banaiya aap bahut simple way ma. Samjata hai aur jaldi isliye aap Sara chapter ka video banaiya 🎉
Sir "The Fundamental Unit Of Life: Cell" ka part 2 please upload kr digiye. Aapke video ke liye chapter aadha pada hai. Please complete video(s) upload kr digiye, next parts.
Sir please uplaod the biology part of fundamental life that you did in live stream kuch bhi samajh nahi aya please do it on the white board and then complete the chapter
Yes dear... I see aapko pentab wala method suit nhi karta hai...
Sure abse ham aapko whiteboard par hi apko padhayenge 😃
@@Science_by_Armaan video daloge na vapis jo live me padhaya tha
Sir 3rd equation se bhi 600m aa sakta hai
yes dear... good job
Sir please is matter arround us pure ka detailed video lana mujhe dought hein
Explained everything and solved all the doubts
Sir please more videos upload karo class 9th
Sir Sara samajh aagaya thank you sir 🙏 ❤
Thanks you sir 😊😊ap bahut Accha samchate ho thanks you sir please aur numaricals karvayiye na 🙏🙏
sir pls bring new lectures i want to finish half yearly syllabus in summer holiday
The fundamental unit of life part 2 please
Sir kuch kuch Intext questions mein bahut dikkat aa rhi h 😢
2. A farmer moves along the boundary of a square field of side 10m in 40s. What will be the magnitude of displacement of the farmer at the end of 2 minutes 20 seconds from his initial position?
Mera 2-3 baar alag alag answer aaya…
Dekh bhai/ bhehen
Iss question me square ki side 10m de rakhi hai aur koi farmer hai Jo iss square ki boundary pe ghum raha hai aur voh pure square jaise field ki Puri boundary ko 40s me complete kar Raha hai. Toh question pucha hai displacement nikalo 2 mins 20 seconds ki
Toh first of all boundary pe ghumna matlab perimeter bol sakte because farmer pure boundary pe ghum raha hai and perimeter matlab koi bhi figure ki boundary ka sum toh perimeter of square = 4 × side = 4 × 10 = 40m ab voh farmer total boundary ko 40s me cover kar rha hai toh hum yeh bhi toh bol sakte haina ki 1 round cover kar rha hai farmer 40s me kyuki Jo total boundary hai which is 40m usko hum 1 round le lete hai matlab 1 round voh kisi ek corner se chalu Kiya aur ek corner pe aa gaya so if 1 round = 40s toh 2 round me kitne seconds lega simply 1 round × 2 = 40 ×2 = 80m , aur 3 round karega 3× 40 = 120m aur vaise hi 4 rounds bhi ab displacement hota hai the shortest distance basically a shortcut toh ab question bolta hai ki displacement Hume nikalna hai 2 min 20s me toh sabse phela voh farmer 2min 20s pe konse point pe rhega uss square field ke?? Toh ek baat batao ki 2min 20s hota kitna hai?? 2min = 2× 60 = 120s and 20s = 120+ 20= 140 seconds matlab ki voh farmer kitna distance cover kara hoga humne nikala ki 1 round = 40m
2 round = 80m ,3 round = 120m and 4 rounds = 160m ab
140m voh kab pochega jab 3 se 4 round ke bich me ho toh let's check ki voh kitne rounds me cover karega itna distance 3.5 × 40 = 140 m toh manlo voh Point A se chala toh voh fir Point A pe aaya toh iska matlab hai ki voh 1 round cover karliya par isme toh sirf 40 m hua aur 2 round me 80m , 3 round me 120m par 3.5 rounds me voh 140m kar payega matlab 4th round hone se kahi bich me ruka hai specifically bolu toh adhe point pe ruka hai toh let the point Be C toh Ab question puchta hai ki 140m pe or 2mins 20s ki displacement batao matlab A se C tak ka shortest path batao basically A se C tak ki shortest length toh ek straight line hi hoga ab kuch triangle sa bana hoga toh. Hume vaha pe basically hypotenuse nikalna hai and the formula for it is H^2 = P^2 + B^2 ab base hai 10m perpendicular yaani height bhi 10 m hai kyuki square ki ha ek side is equal toh H^2 = 10^2 + 10^2 = 100 + 100 = H^2 = 200
Therefore H = square root of 200 ab 200 ke liye koi Aisa number nahi hai jisko ussi number se multiply karke 200 mile toh prime factorisation karlo so Hume milega 10×10×2 so H = √10^2 ×√ 2
H = 10 × √2 = 10√2m aagaya answer finally 😢😢 my fingers are tired
H= √10 × 2
Pls pura message padhna bhot mehnat lagi hai mene bhot basic se explain Kiya hai
@@devrajsingh5206 Thank you so much Finally mereko answer mil gya.
Glad to know🙏🙏
Acceleration me ans. Ke upar -1 or -2 kyu likhte h reply plz..
My first comment
It's good 👍🏻... Also try to solve the question asked in this video. I'm waiting for your answer
Sir please uplaod the biology part of fundamental life that you did in live stream kuch bhi samajh nahi aya please do it on the white board and then complete the chapter
@@Science_by_Armaan Sir please uplaod the biology part of fundamental life that you did in live stream kuch bhi samajh nahi aya please do it on the white board and then complete the chapter
@@ShivanshMishra-ni5ucYes!! Some distractions are always there in any live session for both the teacher, as well as the students. Rather, I always feel so confident when he teaches on the white board 😊

Ok sir kali jayenge running ka liya
Thank you sir ❤🎉
Sir please extra question krwa dijiye
THANK YOU SIR ❤
Mene ye video end tak dekha sir
very good.. it is actually good to end things that you begin! 😀

@@Science_by_Armaanthank u sir but sir ye formulas ko aur jyada practice krayo
Sir Maine complete dika or sir mujhe ( per meter squre or per meter) ko use ker na nahi aata kya sir aap explain ker sakte hai please sir 😢😢😢😢
Sir class 8 science ch Force and pressure please sir please sir
Your studying ideas 💡 are very good
Sir app online batch start karo
now I understand we have to solve numerical by the formula I am right or not
a = 12 m/s
Distance = 600 m/s
600m h ans third equation se
Sir kass app hmare school Mai ake teacher hote 😢
S=600m
Sir first questin samj nahi aaya
How can I score 90 + in science class 9
Sir mera 0 ans aa raha ha

PW teachers time kharab karte hai so I don't like pw teachers
@@anilaswal86 yup ! When it about small topic that we can do for 10 or 5 minute but a PW teach in 1 hours . time waste 🤡
Magnet brains wale bhi time kharab krte h.....
@@J_juhitha you got a point! I remember that I was in class 8 they upload 11 hour lecture for class 10 board exam 🤡
