Congrats to all lovely friends who have stepped into New year of ninth grade❣. Hope you rock in this year😇. All the best my dear friends 🤗🤗
Thank you so much you too Bindu 💕👊🏻😝✨

I don't know you bt thank you😊😊 and same to you👍✨
Thnx sis
Thank you so much mam
My teacher doesn't explains at all.. this numericals.
I thought that i will not be able pass the sci sub due to physics
I was having fear
But due to ur explaination ...
Now i have no fear because of ur explaination ....
Thanks... Once again ✨
👍🏻
Legend are watching before on day of Exam
Thanks you mam very nice teaching 🙏🙏💥
Mam we can 2nd equation s=ut+1/2at2 =3000m
The answer of example 8.5 Is definitely correct but to make the answer more simpler we can also do the multiplication of 72kmph by 5/18
yes
Thank you bro made you made it simple😊
Mam in example 8.5 we can also use second equation of motion.
Thank you mam 😊💖 ... I ve totally understand the concept as well as problems .... Keep on do videos to make students like us to be a topper 🏆🥇🎉
Thank you mam I have can't understood the concept before but now all doubts are clear in this chapter 💗🙏🏻💗💗
Mam we can also divide the number which is given in km to metre by multiplying it by 5/18, by this we can multiply any number.but when we have to change metre to km we have to multiply the number which is given in metre by 18/5.
Yes
Yess

@@syedshafi7899 🤣its okk bro
Yes
Better than our physics teacher
true mine also doesn't explain well
My sir say's that study at
home because he couldn't explain the chapter himself 🙄🙄🙄
More better than our physics teacher
M/s into km/h- multiply by 5/18
Km/h into m/s- multiply by 18/5
Short form to convert 👍
No from km/ hr to m/s 5/18
Exam in one hour 😫i hope I'll do it well
9:36 we can also use 2nd equation, because it's asking the distance covered in that time and 2nd equation is also position-time relation
Yes u can as u can see it example no 8.6
We dont? Its equation 3 that maam used
Thank you mam.. I understand very clearly.... Good class... I like it.. 🥰🥰❤️❤️
Mam, average speed and average velocidad is formula of speed and velocity
It is too useful thanks for to medam Mansi
Very nice explanation, it is understandable by everyone.
Excuse me maam in this one numerical can we use 2 equation.
If yes, I have tried but the answer is different
Thank you soo much ma'am kal exam he meri and muje ye topic bilkul nahi aa raha tha but all thx to you I have understood everything💖✨
Lots of good wishes from my side
East and West Mansi mam is best kaun kaun is Baat Ko agri karta hai

Mam ya 1000/3600 ka formula thorda confusing hai tou uske jagah 5/18 le sakte hai?
Q ki 5/18 yaad karne mei easy hai aur equal hai 1000/3600 ke
Yes, you can use it. It's easy
Mam how we can know that which is equation to use in question.like you use 3rd equation why not other equations??
Mam initial velocity is 10m/s
Mam to turn In meter per second we can also multiply km per hr from 5 upon 18
Mam mam pls pls very impoertant dbt pls tell that in Example 8.5 kya s yaani displacement nikalne ke liye hm 2nd equation of motion ka formula use krskte h pls btadeejiye mam
jaise aapne 3rd equation ka use kra h uski hi jgh 2nd equation of motion qki vo directly
S= ut+1/2atsquare h
pls mam btadeejiye
You are the world best teacher
Mam why did we use third equation of motion......
Same question
Bcz 1st equation says that -velocity-time
2nd=distance -time
3rd=distance -velocity
Here, they have given distance and velocity bcz of this we use 3rd equation of motion 😊....
Tnku soo much ma'am 👍♥️♥️♥️
Can anyone tell ki konsi equation humhe kb use krni h ?? And In first example for find distance we use equation kya hum normal formula nhi use kr skte please anyone tell me
You are best teacher you are God gifted 🥺
😂😂😂😂😂😂
Thank you for giving time for screenshot
Thank you mam in this video
Mam can we use the formula for finding distance (s)
S=ut+1/2 at^2
Jo mam ne use kara wo jaada easy hai
Are bhai mam ne bi to ye hi use kara tha 😂
Yes I have also think
Ma'am if we want we can also solve 8.5 2 part by s=it+1/2at2
Ig we can cuz in text this formula is used
Thank you ma'am
Who are the guys who watch this video before your Physics exam.
Tq mem this was very helpful to me 🙏
No worries when mansi maam is here
Thank uhhh... Mam you have the talent to make anything easy
In example 8.7 there is important to use second equation...plz answer this question tomorrow is my exam,😢
Please update the video of physics ch 2 also 🙂
Ma'am can we use 2nd equation of motion in Example 8.5? I tried using it but the answer is different from this
Yes we can use
Yes ma'am
Mam we can even use a=v-u/t ex8.7
Mam what is SI unit of acceleration
m/s
Mam example 8.5 mein (ii) part mein ..equation of motion ka 2nd equation (S=ut+½at²) kyu nahi lagaaya ...........
Dono lga sqte hai
3rd wala jada easy he but me personally 2nd use krta hu kyunki confusion kam rehti he
Ha
mam if the equation is different but the answer is same so is my answer wrong?
4:46 we can also use second equation of motion . Use second equation of motion also give same answer as third equation of motion
Thank you Akka I can understand clearly
Thank you ❤️
When to use which equation
Mam please discuss new syllabus of class 9th
Mam please
Mam please
Mam please
Mam please
Mam please
Mam please
Yes ma'am plz
Watching this video 20 days before annual exam . And I finally undestand this ch before 20 days remaining 😂😂😂
Mam please help in exemplar also
I am 9th std. Pricipal for physics so they explanation is too good
Mam*5\18 sa multiple hoga
In second part we have to find the distance but mam has written s which stands for displacement...why so??
Ohh man same question 😭
Thank you ma'am for your well- explanation
My exam is tomorrow it's already 2:57 pm and I have just started this chapter
0:30
I lobe uh ma'am 😅❤️
Mam hm log second equation s bhi nikal sakte the n
In ex 8.5 2nd part we can even take the formulae s=ut+1/2at^2
s=0x300+1/2x(1/15)300^2
=0+1/2x6000
=3000m
And when we convert it into km we get 3km....❤
Great 👍
U can also take third equation bcz there they have given distance and velocity bcz of this we use 3rd equation 😊
And once u read the equation of motion part there they have already given 😅😊
I really like your teaching man thankyou so much mam from the bottom of my heart.
Thanks ma'am ❤️
Thanku so much mam ❤
Mam 5 upon 18 me chats he km per meter
Mam 5/8 se bhi convert Karie sakte hai aur vo easy hai
Mam, can't we use second equation for distance
Exactly
Hum 72 km/h ko 5 by 18 se multiply nahi kar sakte hai kya
in 13:03 this part do we need to use bdmas for the answer? Bcz my answer is coming different. Pleasee help 😭
Mam why do you not apply this formula : 2as = v^2-u^2 in example 8.7
thank you mam you have understood very well
Mam app 3d equation be laga dijiye na please
7:14 2nd question start
Mam pls 9.1 to 9.6 ka video daliye
Mam Thank 😊
Ma'am ty 2maro is my exam itz very helpful to me
Ncrt question an artificial satellite is moving in a circular orbit of radius 42250km. Calculate its speed if it take 24 hours to revolve around the earth. Please mam solve this problem
Mama a S=ut+1/2 at-2 see bi kiya ja sak ta he na
mam pls science chapter ki videos bhi dalo
Ya
Bhai ye physics bhi science ka hi part hai
Why can’t we use the 2nd equation in the(ii) part...it says s= ut+1/2at(2)
Thank you ma'am ❤
Nice mam
thanks MAM, i can not solve the numericals problems but now i can do easily😄
Thank you mam
Thankyou so much ma'am aap concept kitni achi tarah se claer kar deti hai🥰❤️
Fuck it's clear
Mam hum meter pet second ma convert karna ka leya 5/18k ka muntiplied kar sakta ha Mam give the answer tomorrow is my exam
Thanks mam
Thank you! Mansi mam ❤😊

🎉🎉🎉
Ki points me answer kaise ata hai please define karke batieaa
Can we use 2 nd equation
Please answer😢
Mam why we don't use eq 1 to find acceleration in ex 8.5??
Equation 1 ko todkar hame
Akhir me a=v-u/t he karna padega
And acceleration ka formula bhi yahi hota hai so simple rehga sidha acceleration ka formula use karna
Hope you understand
Thank you..
Mam why are you not make video on chapter 2of chemistry
Effect 6:40
I am Sarina Verma . Like you and your video
U r great 🎉
Mam plz can you solve the example 8.7 by equation no. 3
🙏🙏
